Growth and prosperity of a nation depends on the search,
development and management of its mineral resources. Minerals constitute
an important raw material and a valuable natural resource in the industrial
development of the country. Due to increased competition, liberalisation
and globalisation world-wide, the markets for minerals have been growing
both in diversity and magnitude terms.
The minerals and mining industry is a key segment of the
Indian economy, with India being highly endowed with vast mineral resources.
The country's accelerated growth rate warrants a rapid development of
the mining sector, on which most of the basic industries in the manufacturing
sector depend. Extraction and development of minerals are closely interlinked
with other natural resources like land, water, air and forest. Hence,
the management of this precious resource and its optimal and economical
use are matters of national importance.
Three kinds of mineral concessions are recognized in Indian
law. They are:-
- Reconnaissance Permit (RP) - granted for preliminary
prospecting of a mineral through regional , aerial, geophysical or geochemical
surveys and geological mapping.
- Prospecting License (PL) - granted
for undertaking operations for purpose of exploring, locating or proving
mineral deposit and
- Mining Lease (ML) - granted for undertaking
operations for winning any mineral. The main opportunities in the mining
sector are in the development and production of surplus commodities such
as iron ore and bauxite, mica, potash, few low-grade ores, mining of small
gold deposits, diamonds, platinum group of metals and other rare metals,
Under the Constitution of India, management of mineral
resources is the responsibility of the Central Government and the State
Governments in terms of the Union List and State List respectively. The
Central Government is the owner of the minerals underlying the ocean within
the territorial waters or the Exclusive Economic Zone of India, while
the State Governments are the owners of minerals located within the boundary
of the State concerned. The Central Government, in consultation with the
State Governments, formulates the legal measures for regulation of mines
and minerals in order to ensure basic uniformity in mineral administration
as well as to maintain the pace of development of mineral resources, in
consonance with the national policy goals.
At the Central level, the 'Ministry of Mines' is the nodal
agency for overall growth and expansion of minerals and mining sector.
It is responsible for survey and exploration of all minerals (other than
natural gases, petroleum and atomic minerals); for mining and metallurgy
of non-ferrous metals like aluminium, copper, zinc, lead, gold, nickel,
etc. as well as for administration of the 'Mines and Minerals (Regulation
and Development) Act, 1957' in respect of all mines and minerals (other
than coal, natural gas and petroleum). At present, the Ministry is having
two subordinate offices, namely:-
- Geological Survey of India (GSI), Kolkata - is one of
the biggest national survey organisations of the world and one of the
largest scientific organization of the country. It has been functioning
as a vital arm of the Ministry, providing basic and specialised information
on mineral resources as well as contributing to their development and
management. It seeks to collect, synthesize and update the data about
the sector on a continuous basis as well as refine the nation's geoscientific
information and knowledge. Such database is the basic source of accurate
and specialised geoscientific inputs to a wide spectrum of end users
covering Government/semi-Government agencies, multi-national and private
organisations involved in resource exploitation, research, education,
- Indian Bureau of Mines (IBM), Nagpur - is engaged in
the promotion of scientific development of mineral resources of the
country, conservation of minerals and protection of environment in mines,
other than coal, petroleum and natural gas, atomic mineral and minor
minerals. It performs regulatory functions, namely enforcement of the
Mineral Conservation and Development Rules, 1988, the relevant provisions
of the Mines and Minerals (Development and Regulation) Act, 1957, Mineral
Concession Rules, 1960 and Environmental Protection Act, 1986 and Rules
made there under. It provides technical consultancy services to the
mining industry for the geological appraisal of mineral resources, and
the preparation of feasibility reports of mining projects, including
beneficiation plants. It functions as Data Bank of Mines and Minerals
and publishes statistical periodicals.
The public sector undertakings (PSUs)
under the Ministry are:-
- National Aluminium Company Limited (NALCO),
- Hindustan Copper Limited (HCL), Kolkata and
Exploration Corporation Limited (MECL), Nagpur
While, there are three research institutions, which are autonomous bodies of this Ministry, such as:- Jawaharlal Nehru Aluminium Research Development and Design Centre
, Nagpur; National Institute of Rock Mechanics (NIRM)
and National Institute of Miners' Health (NIMH)
, Nagpur. The Ministry's science and technology programme
covers the disciplines of geology, exploration, mining and environment, bioleaching, beneficiation, rock mechanics and ground control and non-ferrous metallurgy. During the current year, 15 new projects have been received for consideration and there are 6 ongoing projects.
The Mines and Minerals (Development and
Regulation) Act, 1957, (MMDR Act) and the Mines Act, 1952, together with
the rules and regulations framed under them, constitute the basic laws
governing the mining sector in India. The MMDR Act, 1957 lays down the
legal frame-work for the regulation of mines and development of all minerals
other than petroleum and natural gas. The provisions of the Act and the
Rules are reviewed from time to time and harmonised with the policies
governing industrial and socio-economic developments in the country.
The Central Government have framed
the Mineral Concession Rules, 1960 for regulating grant of prospecting
licences and mining leases in respect of all minerals other than atomic
minerals and minor minerals. While, the State Governments have framed
the rules in regard to minor minerals. The Central Government have also
framed the Mineral Conservation and Development Rules, 1988 for conservation
and systematic development of minerals. These are applicable to all minerals
except coal, atomic minerals and minor minerals.
In pursuance of the reforms initiated
by the Government of India in 1991, the Ministry had formulated the National
in 1993 and offered several incentives and concessions
to the investors. The policy recognized the need for encouraging private
investment, including foreign direct investment and for attracting state-of-the-art
technology in the mineral sector. The basic objectives of the mineral
policy are to:-
- Explore for identification of mineral
wealth in the land and in off-shore areas.
- Develop mineral resources taking
into account the national and strategic considerations and to ensure
their adequate supply and best use keeping in view the present needs
and future requirements.
- Promote necessary linkages for smooth
and uninterrupted development of the mineral industry to meet the needs
of the country.
- Promote research and development in
- Ensure establishment of appropriate
educational and training facilities for human resources development
to meet the manpower requirements of the mineral industry.
- Minimise adverse effects of mineral
development on the forest, environment and ecology through appropriate
- Improve the investment climate for
mining in the country and
- Ensure conduct of mining operations
with due regard to safety and health of all concerned.
In furtherance of the objectives of
the National Mineral Policy, the MMDR Act, 1957 has been amended twice
in 1994 and 1999. The Mineral Concession Rules, 1960 (MCR) and the Mineral
Conservation and Development Rules 1988 (MCDR), framed under the MMDR
Act, 1957 have also been modified. Salient features of the amended mining
legislation are as follows:-
- There is no restriction on foreign
equity holding in mining sector companies registered in India.
- There is a greater stability of tenure
of mineral concessions, since the minimum period of a mining lease is
twenty years and a maximum period of thirty years. A mining lease may
be renewed for a period not exceeding twenty years and may again be
renewed for a period not exceeding twenty years in respect of minerals
specified in Part C of the First Schedule of the Act (MMDR Act). In
respect of minerals specified in Part A and B of the First Schedule
of the Act, such renewal may be granted with the previous approval of
the Central Government. The period of prospecting license now is three
years, with possibility of renewal for a further period of two years.
- Thirteen minerals like iron ore, manganese
ore, chrome ore, sulphur, gold, diamond, copper, lead, zinc, molybdenum,
tungsten, nickel and platinum group of minerals which were reserved
exclusively for exploitation by the public sector, have now been thrown
open for exploitation by the private sector.
- With the 1999 amendment, a concept
of reconnaissance operations, as a stage of operation distinct from
and prior to actual prospecting operations, was introduced. The period
of reconnaissance permit is three years. A reconnaissance permit holder
enjoys preferential right for grant of prospecting licence.
- In 1994, fifteen minerals were removed
from the list of minerals included in the First Schedule to the MMDR
Act, 1957. With further amendments in 1999, the mineral limestone was
deleted from the First Schedule, and permission of the Central Government
is now required for grant of mining lease, prospecting license, and
reconnaissance permit in respect of only ten non-fuel and non-atomic
minerals. These minerals are asbestos, bauxite, chrome ore, copper ore,
gold, iron ore, lead, manganese ore, precious stones and zinc.
- State Governments have been delegated
powers to grant mineral concessions even for areas which are not compact
or contiguous. They also have been empowered to permit amalgamation
of two or more adjoining mining leases.
- Time limits have been prescribed for
conveying a decision on applications for mineral concessions, such as
six months for reconnaissance permits, nine months for prospecting licences
and twelve months for mining leases, etc.
Such policy framework and its subsequent revision has further opened up the sector and increased the inflow of domestic and foreign investment. Foreign Direct Investment (FDI) policy in the mining sector has been gradually liberalized over the last few years. FDI cap for exploration and mining of diamonds and precious stones have been increased to 100% under the automatic route. Also, FDI in the mining sector for all non-atomic and non-fuel minerals have now been fully opened upto 100% through the automatic route, including diamonds and precious stones.
After the introduction of the concept of reconnaissance permit, 263 reconnaissance permits covering an area of 3,62,217.322 square kilometers have been granted till 31.12.2007, of which 56 reconnaissance permits for an area of 76482.58 square kilometers were granted during the year 2007-2008. The States for which reconnaissance permits have been approved are Rajasthan (48), Andhra Pradesh (47), Karnataka (43), Chhattisgarh (29), Odisha (24), Madhya Pradesh (41), Uttar Pradesh (14), Gujarat (4), Jharkhand (3), West Bengal (3), Haryana (1), Kerala (1), Arunachal Pradesh (1), Maharashtra (3), Manipur (1).
However, the demand growth for metals and minerals, domestic as well as global, is continuously pushing up the prices. In India, the Wholesale Price Index for non-fuel minerals (base year 1993-94=100) stood at 429.8 in August 2007 and the corresponding index for August 2006 was 424.5. The minerals included in the Wholesale Price Index are bauxite, chromite, iron ore, manganese ore, asbestos, barytes, dolomite, felspar, fireclay, fluorite, gypsum, Kaolin (china clay), limestone, magnesite, ochre, phosphorite, silica sand, steatite, and vermiculite. The Wholesale Price Index for metallic minerals was 622.7 in August 2007 as compared to 618.2 in August 2006 and that of other minerals was 125.2 in August 2007 as compared to 118.7 in August 2006.
In order to encourage greater investment
in exploration and mining as well as remove bottlenecks which hinder the
productivity and efficiency of this sector, the Planning Commission has
set up a 'High Level Committee' under the Chairmanship of Shri Anwarul
Hoda, Member, Planning Commission. The Committee aimed at reviewing the
National Mineral Policy and recommending possible amendments to the MMDR
Act, so as to attune them to the present requirements of the world economy
for evolving of mining code adapted to the best international practices,
streamlining and simplifying of procedures for grant of mineral concessions
to reduce delays, strengthening the infrastructure for mining activities,
etc. Some of the other terms of reference of the Committee are to:-
- Suggest the changes needed for encouraging
investment in public and private sector in exploration and exploitation
- Review the procedures for according
clearance to mineral exploration and mining projects under the Forest
(Conservation) Act, 1980 and Environment (Protection) Act, 1986, and
suggest ways for speeding them up.
- prioritise the critical infrastructure
needs of the Indian mining sector and make recommendations on ways to
facilitate investment to meet these needs.
- Examine the implications of the policy
of mineral-rich States to make value addition within the State a condition
for grant of mineral concession and make appropriate recommendations
in this regard.
- Examine ways of augmenting State
revenues from the mineral sector and
- Examine any other issue relevant
for stimulating investment flows and inducting state-of-the-art technology
into the sector.
As a result of all such incentives and measures, the index of mineral production, excluding fuel and atomic minerals, (base year 1993-94=100) for the year 2007-08 is expected to be 170.39 as compared to 163.21 in 2006-07, showing a positive growth of 4.4 per cent. The total value of mineral production (excluding atomic minerals) during the year 2007-08 is estimated at Rs. 99,533.10 crores. During the same year, provisional value of fuel minerals account for Rs. 68,229.40 crores (69 percent of the total value), metallic minerals are estimated at Rs. 19,755.66 crores (20 percent of the total value); and non-metallic minerals (including minor minerals) are valued at Rs. 11,548.04 crores (11 percent of the total value).
The provisional value of export and import of ores and minerals, during the year 2006-07, was Rs. 80,912 crore and Rs. 3,05,028 crore respectively. Diamond (mostly cut) was the principal item of export during 2006-07, which accounted for 59.2 per cent, followed by iron ore with a contribution of 21.8 per cent, granite with a contribution of 5.8 per cent, alumina with a contribution of 2.3 per cent, precious and semi precious stones with a contribution of 1.0 per cent and chromite with a contribution of 0.98 per cent. Building and monumental stones, emerald, coal (including lignite), marble and bauxite were the other important minerals exported during the year 2006-07. While, petroleum (crude) was the main constituent of mineral import during the year 2006-07, which accounted for 69.9 percent of the total value of import of ores and minerals, followed by diamond (uncut) with 10.8 percent. Coal, coke, copper ores and concentrates, rock phosphate, sulphur and iron ore were the other important minerals imported during the same year.
Thus, mines are integral part of India's
industrial set up. They offer innumerable opportunities for exploring
and discovering various sub-surface deposits using modern techniques.
They are useful for the investors the world over for manufacturing several
value-added products. Therefore, it is imperative to achieve the best
use of available mineral resources through scientific methods of mining,
beneficiation and economic utilisation. Also, it is essential to keep
in view the present and future needs of the country and take all possible
steps to ensure indigenous availability of basic and strategic minerals
for meeting the global challenges.

Actively seeking a new JV partner
Cradle Arc – 100%
About the project
The 137 km2 Kossanto West Gold Project in western Mali, comprises two primary permit areas, Kobokoto Est and Koussikoto.
The Project is located over a substantial area of the regionally significant Main Transcurrent Shear Zone, which is considered to be one of the major controls on gold mineralisation in western Mali and eastern Senegal.
Kossanto West has been subject to soil geochemical sampling, pitting, trenching and scout drilling since Cradle Arc acquired the project in 2013 and the results have been extremely encouraging, demonstrating high-grade gold mineralisation.
The project was formally being advanced a part of a JV with Randgold Resources (Mali) Sarl who confirmed soil anomalies identified by Cradle Arc and identified NW-SE striking lithologies in the area in addition to several major geological domains that are interpreted as basal sediments and clastic rocks intruded by a range of different plutonic rocks in the east and a mélange of volcano-sedimentary rocks in the west.
In accordance with the terms of the JV Agreement, Randgold has provided a comprehensive database of the results from their field activities over the past two years. This data, along with the Cradle Arc’s historical data, will be available for review by potential future partners as Cradle Arc actively seeks a new JV partner for the continued exploration and advancement of the project.

Florence Copper is possible because of a rare copper deposit located in the Historic Copper Corridor of Arizona – a region steeped in copper mining history.
The deposit is large, and it lies 400 to 1,200 feet below the surface of private and state-owned land in Florence, Arizona.
The natural features of the deposit allow the copper to be extracted without disturbing the land and with minimal environmental impact. The deposit is porous and naturally shattered – this allows the copper to be recovered using a water-based solution in a process called in-situ copper recovery (ISCR). ISCR requires no open pit, no tunneling, no waste dumps, and none of the large equipment typically associated with traditional mining activity.
The extraction process occurs deep in the bedrock. It involves a simple combination of physics and basic chemistry to dissolve and then pump copper-rich solution to the surface. Once at the surface, the solution is converted into large sheets of up to 99.999% pure copper cathode.
During its lifetime, Florence Copper is estimated to create close to 500 jobs for Pinal County and generate $3.4 billion in economic activity for the State of Arizona. The project already has completed a successful Production Test Facility, during which over 1 million pounds of copper were produced. Florence Copper now is in advanced permitting stages to expand to commercial operations.

More than 52,000 mine and quarry workers attended 1,197 Safety Reset sessions - to refocus on what it means to be a safe industry, free of fatality and serious harm. An online survey of mine and quarry workers who attended a series of Safety Reset sessions was conducted by the Queensland Department of Natural Resources, Mines and Energy (DNRME). It was conducted over six weeks ending in late August 2019. Survey respondents answered five questions to provide general suggestions on how safety outcomes could be improved in the mining and quarrying industries.
In addition to providing analysis of the collected survey data, Ronan Analytics conducted targeted telephone interviews with industry stakeholders and Safety Reset attendees from mining and quarrying sites to identify themes and sentiment following the Safety Reset sessions. The purpose of this data project was to extract the most value from the survey and interview responses and to formalise the results into a report providing insights into the themes and issues raised during the Safety Reset initiative. It is intended to be read by industry workers and stakeholders including worker representatives, industry leaders, and government to highlight areas of concern, and to inform further actions.
The findings are generally consistent with those of the more formal reviews and highlight a desire for improvement in three areas:
- Safety leadership
- Workforce practices
- Training and procedures.

Bulk loading filters, also called rock catchers or de-rockers, are used to keep oversized lumps of material from entering the bulk loading system onboard ships or drilling rigs, potentially resulting in damage to equipment or piping. The bulk loading filter is fitted with a heavy duty mesh (mesh hole size of 10 mm), located inside the package, which crushes oversized material or traps it into a small collection area for removal.
The package is fitted with Weco Wing quick connection couplings (fig. 200 or equivalent, other options can be identically accommodated) as well as pressure indicators located upstream and downstream from the mesh, allowing for easy visual identification of the operational condition of the filter. The package is also fitted with a pneumatic air connection (ball valve and check valve) which can be used to clean the interior.
The bulk loading filter package has been designed accounting for design pressures of up to 16 bar, and minimum design temperatures of -20ºC. Its introduction into the bulk loading system will impose a minimal head loss which can increase as the filter gets clogged, hence the importance of keeping regular readings of the local pressure indicators to ensure the package is operating in optimum working conditions. The size of the collecting mesh can be adjusted to other mesh hole sizes as preferred by the customer.
Besides bulk loading filters, we can design and supply other types of equipment such as bulk tanks or cyclone dust collectors.


Lynas, which mines its rare earths in Western Australia and ships the raw material to Malaysia for processing, had previously set a target to boost its output by 50 per cent to 10,500 tonnes a year by 2025. However, the speed of the global push to decarbonise has led the company to increase its output goals.
The US government has also signed a $120 million deal with Lynas for it to build a processing plant in Texas, with geopolitical tensions fuelling concerns that China’s control of more than 80 per cent of global rare earth supplies could harm energy security.
“Demand for magnetic materials is forecast to double by 2030, but this demand is within a market which is structurally ill-equipped to meet the increased demand,” Lacaze said at the Diggers and Dealers forum on Wednesday.
“In a nutshell, China has leveraged its resource and processing know-how to develop a dominant position in the supply of essential materials for green future-facing industries. And that is why you will be hearing from so many project proponents in this space.”
Meanwhile, fellow critical minerals miner Pilbara Minerals announced on Wednesday it had sold another shipment of its hard-rock lithium concentrate known as spodumene, with prices remaining high as clean energy needs drive demand for the essential battery mineral.
Pilbara said it had accepted a bid with an implied price of $US7012 ($10,114) a tonne for 5000 dry metric tonnes of its product in its eighth auction – $US5 shy of its record price per tonne achieved in June and up from its last auction in July.
Lithium prices have sharply increased as global electric vehicle sales rise, with automakers increasingly investing in supply chains to secure the scarce mineral, which is essential for electric batteries.

The Dolaucothi site in West Wales's represents one of the few worked gold mines in Britain and, to our knowledge, is the only one open to the public today. Evidence suggests that the Roman's first worked the Dolaucothi Gold Mines on a large scale, although it is not impossible to assume that some activity occurred here even earlier. This being the case, it would undoubtedly have been on a much smaller scale and those workings would have disappeared in the massive Roman operation.
Normally to obtain gold from deep-mined ore requires the removal of various waste products, like arsenic, before the gold can be released. As the Romans' almost certainly didn't have the technology to treat ore in this manner, they concentrated on open-cast mining of so-called 'free' gold. This operation depended on nature's natural weathering processes to remove the waste products for them. Only high-grade material would be selected from the surface, crushed with a mortar and pestle, and finally ground down by rotating quern stones, similar to those used in flour milling. After some sieving, the fine gold particles would be collected from large terraced washing table's, cut either into the natural contours of the bedrock or constructed from timber. Water was obviously very important in this process and evidence of large water tanks and water channels can be found above most of the open cast pits. This process of gold abstraction was generally very inefficient and was probably only profitable because of the abundant use of slave labour.
After the Roman withdrawal, the history of the Dolaucothi Gold Mines becomes very sketchy, and it is uncertain whether mining activities continued in Saxon or medieval times. Again, had they been worked during this time, it would probably have been on a relatively small scale, and any evidence would have blended naturally into the former Roman works. What is known, however, is that considerable interest was shown in other West Wales mines during the 16th and 17th centuries, and it seems reasonable to surmise that the Dolaucothi Gold Mines would have attracted the attentions of these same prospectors.
Certainly, during the late 19th century and first half of the 20th century, numerous workings continued at this site. In 1844 the eminent geologist Sir Warrington Smyth rediscovered gold here, and in 1853 three Australians set up a water- driven stamp mill for crushing ore from the open cast pits. This operation was short lived, but some small-scale workings were recorded to have commenced again by 1871. These increased in magnitude, and concentrated on underground mining of the ore rather than the open cast method previously adopted. Many different companies successively ran the operation at Dolaucothi until Cothy Mines Ltd. ceased workings in 1912.
Abandonment of the gold standard in 1931 created renewed business interest, and a new company, Roman Deep Ltd. was formed in 1933 to assess the feasibility of continued mining at the Dolaucothi site. Having proved viable, mining continued here until 1940 when the mine buildings were finally dismantled, and 500lbs of weeping explosives detonated.
In 1981 the National Trust (owners the estate) embarked on a trial with the University of Wales to provide guided tours of the site. Realising the educational benefits, coupled with the potential as a major tourist attraction during the summer months, the site has steadily been developed. With the closure of the Olwyn Goch lead-zinc mine in 1988, all the surface buildings and equipment there were moved to Dolaucothi and re-erected. Now able to provide the visitor with a more realistic experience, the Dolaucothi Gold Mine makes a great family outing. Adults and children alike get a thrill from 'sieving for gold', or donning a miners' helmet and lamp to take a guided tour of the underground workings. As an added bonus, the scenery is fantastic with spectacular views across the estate and beautiful woods, heady with the smell of Bluebells, in the spring. Plenty of information is available in the visitor centre, and there is also a shop and a cafe on site.


CAIRO, Egypt, February 13, 2018-Australian Ambassador Neil Hawkins is delighted that Australian mining companies are showing increased interest in Egypt\u2019s mining sector. \u2018Egypt has huge potential in mining, as the dozens of Australians working at the Sukari mine near Marsa Alam can attest\u2019, he said. \u2018We look forward to increasing cooperation between Australian and Egyptian mining officials and companies in 2018.\u2019 To kick-start that cooperation, the Australian Embassy in Cairo, in collaboration with the Western Australian Department of Mines and the Egyptian Mineral Resources Authority, will be coordinating a two-day capacity building workshop on best practices for sustainable mining governance in Cairo from 14- 15 February 2018. Egypt has strong potential to develop further its mining sector and attract significant international investment. Australia is an international leader in mining with years of experience and many strong, successful mining companies active around the world. The Australian Embassy is proud to be supporting the visit to Egypt by two experts from the Western Australian Department of Mines, Industry Regulation and Safety, who will share their expertise with Egyptian officials from the Ministry of Petroleum and Mineral Resources and the Egyptian Mineral Resources Authority. The Australian Embassy views this as a valuable opportunity to facilitate exchanges and further cooperation between mining and resource ministries from Egypt and Australia. The workshops were made possible by the kind support of Australian mining companies Allied Gold Limited and Resolute Mining Limited, both of whom are actively engaged in Egypt, as well as the Egyptian Council for Sustainable Development. \u2018Sukari is one of the top ten gold mines in the world. It shows what can be achieved here in Egypt when Australian and Egyptian miners come together and go for gold\u2019, Ambassador Hawkins said.


Sable Resources Ltd., is a Vancouver based mining and exploration company engaged in the acquisition, exploration and development of mineral properties. The Company has focused its’ efforts on the development of precious metal deposits hosted within British Columbia.
The Company has been involved by way of investment in Consolidated Barrier Reef Resources Ltd. (Blackdome Mountain Mine), Skyline Gold Corporation (Johnny Mountain Mine), Taurus Resources Inc. (Taurus Gold Mine), International Taurus Resources Ltd. and International Shasta Resources Ltd. (Shasta Deposit) In 1989, the Company acquired the Baker Mill and Mine, which are located in the Toodoggone area of B.C. from Dupont (Canada) and made an agreement with International Shasta to mine and mill a part of the Shasta Deposit, which is located 11 km (7mi.) away from the Baker Mill. Sable has since acquired a 100% interest in the Shasta Mine, and are currently engaged in underground development of this key asset.


Devil is located on both banks of the Kuskokwim River, at the mouth of
Red Devil Creek. It lies 75 air miles northeast of Aniak, 161 miles
northeast of Bethel, and 250 miles west of Anchorage. It lies at
approximately 61░ 45' N Latitude, 157░ 18' W Longitude (Sec. 06, T019N,
R044W, Seward Meridian). The community is located in the Kuskokwim
Recording District. The area encompasses 24 sq. miles of land and 2 sq.
miles of water.
The village was named after the Red
Devil Mine, established in 1921 by Hans Halverson when numerous
quicksilver deposits were discovered in the surrounding Kilbuck-Kuskokwim
Mountains. By 1933, the mine was producing substantial quantities of
mercury. Although the mine changed ownership twice over the years, it
continued to operate until 1971. The mine produced some 2.7 million
pounds of mercury during its operation. A post office was established in
1957 and a state school opened in 1958.


Aru-Lõuna limestone quarry was opened in the 1960-s and at this moment it is the biggest limestone quarry in Estonia. Limestone from the quarry is used as raw material and aggregate for cement. The size of the land is 411.58 ha, including extraction permit area- 317.34 ha.
Aru-Lõuna limestone quarry is located in North-Estonia, West-Viru County, Andja village. Toolse river is about 500 meters west from the mining claim and Kunda river is about 300 meters from the east. Through the western border of the mine runs Kunda-Rakvere railway. The mining allotment and the mine service area is not located in a nature reserve or Natura 2000 area. There are no natural objects or cultural monuments, no limitations on the protection of cultural monuments. Nearest Natura 2000 area is 500 meters away from quarry, around Kunda river.
Quarry is located under the groundwater level, that’s why there should be waterbody after restoration. Since the quarry is not opened to the lowest point, all the resources near the border areas has not been excavated yet. At the moment, restoration can be done only in areas, where mining is finished.
North from Aru-Lõuna quarry is located old limestone quarry, where the mining activity is ceased and quarry is restored many years ago. Now, it is a very popular among fishermen, there are also a lot of waterfowls and reptiles that inhabit in the flanks of the rocks near the water.
About 12 million m3 of water is pumped out of the quarry to the Toolse river in a year. The pumped out water is clear and oxygen-rich, therefore there is also diverse fauna. Due to constantly moving shallow water, where vegetation grows, there’s the habitat for common ringed plover (Charadrius hiaticula) and little ringed plover (Charadrius dubius). In the bottom of the quarry, there is a considerable size lake (about 1 m deep), which is a stop for migratory birds. This stop is also found by white-tailed eagles (Haliaeëtus albicilla). Also there are old sifting heaps, where sand martins (Riparia riparia) build their nests.
In a quarry territory, there are also a lot of rabbits, foxes, it’s often seen lynx and traces of bears, elks and wild boars. There are counted over 250 different species of vascular plants during flora inventory. Among others there are also some protected and endangered plant species like military orchid (Orchis militaris), early march-orchid (Dactylorhiza incarnate), board-leaved helleborine (Epipactis helleborine), marsh helleborine (Epipactis palustris) and bristly bellflower (Campanula cervicaria).
Ongoing nature projects:
- Biota inventory
- Bird Life project about sand martins

Fluorite Recovery from Ores Tailing by Using Flotation Technique
The purpose of this study is to recover fluorite from ores tailing which derived from fluorite processing plant in Thailand. Flotation technique was undertaken to improve the concentration. Oleic acid, Methyl Isobutyl Carbinol (MIBC) and sodium silicate were optimized. pH condition was also carried out to find the best condition. The experimental results show that the effective performance when Oleic acid and sodium silicate were utilized at 800g/t and 500g/t respectively. Weak alkaline condition at pH 9 indicated the best effective condition. Therefore, the optimal condition could probably recover fluorite from ores tailing which is great for fluorite flotation in order to raise economic profits.
Keywords - Fluorite Ores Tailing, Froth Flotation, Oleic Acid, Sodium Silicate, Methyl Isobutyl Carbinol (MIBC)


Heavy machinery is synonymous with mining. It’s used in every aspect of the sector from exploration and development of sites to break down and removal of rocks to processing and reclamation. The total number of mines in world is upwards of 25,000 producing industrial minerals and almost 100,000 quarries that produce aggregates used in the construction sector. Regardless of those impressive numbers, mining equipment manufacturers have had some fairly substantial ups and downs over the last several years. In the recent past, the trend was towards decline, but it looks like the market is about to change.
The major mining machinery manufacturers that took some huge revenue hits last year are cheering the upbeat forecast. According to a study by the industry market research firm, The Freedonia Group, growth in this sector is about to blossom. The study they conducted predicts that “global demand for mining machinery is forecast to expand 8.6% per year through 2017 to USD $135 billion.” And that’s good news for everyone.
The study goes on “to highlight the Asia Pacific region and both Central and South America as the fastest growing markets for mining equipment.” According to an article recently published on the Pit & Quarry website: “The study also forecasts strong gains in South America, as mining companies look to develop the region’s sizable deposits of bauxite, copper and iron ore. The dissipation of copper oversupply issues that existed in 2012 and 2013 will allow prices to recover and boost associated mining equipment demand in areas rich in copper, such as Chile and Peru. The Africa/Mideast region will post the next fastest advances, followed by Eastern and Western Europe and North America.”
Steel and aluminum production has also seen growth so the demand for metals mining equipment is keeping pace. Studies show this sector of mining will rise at the fastest pace over the next three years. In addition, construction spending is increasing and global agriculture output is on the rise. Therefore, it will be important that mining equipment manufacturers and all the vendors that work within this sector keep step. Hydroswing® plans to march to the front of the line.
Ironically, the process which is powering the USA and many other parts of the world’s mining, exploration and heavy plant machinery along is a hydraulic process is called “Hydraulic fracturing.” This “fracturing” has made it possible to tap in and release huge oil, gas and other valuable reserves. The shale oil industry has seen the growth of machinery for this sector in both size and numbers, all of which are dependent on hydraulics for power, strength and load bearing.
The use of hydraulics is nothing new to the mining sector. The technology is a standard consideration in their processes. Understanding the magnitude of the market, mining is quickly becoming a strong focus for Hydroswing®. Large and extra large hydraulic doors are making an impact in the marketplace for storage and maintenance of heavy machinery. With Hydroswing®, mining equipment manufacturers can easily house bulldozers, grading equipment, drilling rigs, the latest CAT tippers and a plethora of other machinery in easy-to-access sheds, and ISO shipping container shelters with openings which easily accommodate the latest CAT/TEREX/DEERE/KOMATSU/JCB and SANDVIG machinery. With 70% less moving parts than a bifold door and enormous strength, the Hydroswing® hydraulic door is a simple and cost effective solution that will successfully fit into the ever growing demand in the mining sector. Hydraulics are well known to the mining industry and now mining door systems are following suit.

Collection of History
The area known as Nelson was originally called Eldorado in 1775, by the Spaniards who made the original discoveries of gold in the area that is now Eldorado Canyon. The town was the site of one of the first major gold strikes in Nevada and one of the biggest mining booms in state history. Gold and silver were discovered here around 1859. The rush to the canyon began in 1861, several mining camps were established in the canyon, and a steamboat landing at the mouth of the canyon on the Colorado River, called Colorado City.


Lithium is also known as “white gold” because it is an essential element in the production of the batteries used in electromobility, energy storage and portable electronics. Most of it is mined far away from Germany in countries such as Chile, Argentina and Australia, but this could be about to change.
Scientists from the Karlsruhe Institute of Technology (KIT) have patented a cost-effective technology for extracting the element at geothermal energy plants. In the German and French upper Rhine region, lithium is found in abundance in salty, subterranean reservoirs. “According to our findings, it can be up to 200 milligrams per litre,” says Dr Jens Grimmer from the Institute of Applied Geosciences (AGW) at KIT in a . “If we consistently use this potential, we could cover a considerable part of our demand in Germany.”
Dr Grimmer explains the process he developed with KIT colleagues: “In a first step, the lithium ions are filtered out of the thermal water and in a second step they are further concentrated until lithium can be precipitated as salt.” Their technique has a number of environmental advantages over traditional extraction: it is non-invasive and uses the existing infrastructure of geothermal plants, the element can be continuously extracted there (unlike many conventional extraction techniques), and the water is returned to the ground after use and no harmful substances are released. Furthermore, other valuable elements such as rubidium and caesium can be obtained.
The KIT team are working with industry partners to build a prototype plant capable of extracting several kilogrammes of lithium carbonate or lithium hydroxide per litre. If successful, a bigger plant is planned which could produce thousands of tonnes per year.

Capping abandoned mine shafts
Abandoned Mine Shafts in Australia
According to Mining Australia’s publication, approximately 80,000 abandoned mine shafts are scattered across Australia. Abandoned mines can have significant risks from both public safety and environmental perspectives. Unmarked or poorly blocked mines present a falling danger for both humans and wildlife, and some abandoned mines leach toxic materials into surface water and groundwater on-site and into nearby waterways.
Capping mine shafts with inflatable plugs
Low-pressure inflatable plugs combined with concrete serve as an effective solution for capping abandoned mine shafts. The process begins by inserting a deflated plug into the opening of the shaft. Once positioned, the plug is inflated with an air pump until it expands, creating the formwork on which to pour concrete.
Subsequently, concrete is poured into the shaft around the inflated plug, filling the space and providing structural support while further sealing off the area. As the concrete sets and solidifies, it forms a durable barrier that effectively closes off the abandoned mine shaft, enhancing safety measures and preventing access.

Don’t be fooled; it’s not all gold, gold, gold in the mining business. Other resources such as steel and tungsten are making significant profits for a variety of mining companies – some of which are sure to be using the technology available from industry leaders such as IVolve to assist them with their mighty, mining projects. Indeed, industrial mining technology has never been more in demand. Check out five of the most successful mining projects across the globe.
The Nui Phao Project
This Vietnamese polymetallic mine is rich in deposits of tungsten, bismuth, copper and gold and has been identified as one of the largest tungsten deposits outside of China. With open-pit mining and a low strip ratio, this will be one of the lowest cost producers of tungsten in the world. With its close proximity to local infrastructure, this booming mine just keeps on giving.
Lumwana Copper Mines
This Zambian mine is pumping out copper, cobalt, gold and uranium in the north-western province of the country. Combining an open pit mining method with processing via flotation and/or crushing, this mine is expected to run until at least 2044. The mining project has two major copper deposits – in 2013 alone, the mine produced approximately 260 million pounds of copper!
Delcarmen Coal Project
This one’s about to go boom as a prospective mining project with two EPCs (Exploratory Permit for Coal) granted to the north and east of Kingaroy, Queensland. With an assessment predicting between 30 and 140 million tonnes of the coal, initial exploration will be based on rotary chip holes, followed up with down-hole logging using the usual geophysical tools such as density, gamma, sonic and caliper. A number of potential strategic partners have already made enquiries about getting on board with this project so time is running out if you want to get involved with this one.
Situated 120km north-west of Kalgoorlie, Western Australia, this mine is rich in gold, both ‘in situ’ and potentially viable via exploration and prospecting. As an established mine, its processing infrastructure is already in place and prospects are looking good for this magnificent hole in the ground. A secondary mine at Mt Ida looks to be as equally promising as the Davyhurst Hub.
This Papua New Guinea project may well be having some issues getting off the ground, what with the area being a significant wildlife reserve. Rest assured, though, as long as the right paperwork can be filled out and the right people satisfied, this project will be a sure-fire winner as Papua New Guinea’s next big copper and gold reserve. Stakeholders estimate that the mine will only take up one and half square kilometres of the nature reserve’s estimated 2000 square kilometres.

Scarce gems on Earth! What are rare earth elements form and what are they used for
These two elements are commonly used in various electronic devices and industrial applications.
The 15 elements in the periodic table of elements are known as the lanthanide series. Although they are not truly rare earth elements, the yttrium and scandium can be considered as part of this group due to their similar properties
The 15 elements in the lanthanide series include praseodymium, holmium, terbium, and gadolinium. Also, scandium and yttrium are found in various rare earth element deposits.
These elements are often found in geological deposits. Due to their chemical properties, they can be commonly found in these types of deposits. However, their magnetic and electronic properties are unique to each metal, which makes them incredibly versatile.
Where are they found and produced?
Despite the abundance of rare earth elements, only a few countries have the necessary reserves to produce enough of these metals for their production.
According to estimates, the global reserves of rare earth elements are expected to reach around 120 million metric tons by 2020. China is currently the world’s largest producer of rare earth elements with 44 million metric tons of reserves. Other countries such as India and Russia have around 6 million and 7 million respectively.
Some of the other countries that have significant reserves of rare earth elements include South Africa, Malaysia, Thailand, and Sri Lanka.
Are they really ‘rare’?
Although their names imply that they are rare, the elements are actually relatively abundant in Earth’s crust.
According to the USGS, the more abundant rare earth elements are similar in their crustal concentration to common industrial metals such as lead, copper, nickel, and chromium. The USGS also noted that even the two least abundant rare earth elements, which are known as Lu and Tm, are more common than gold.
The main difference between rare earth elements and ordinary base metals is that the former is more difficult to mine. This is because they are less likely to be found in high concentrations.
What are they used in?
The demand for rare earth elements has been growing due to the technological advancements that have occurred over the past two decades.
Aside from being used in the production of various electronic devices, such as smartphones and computers, these elements are also widely used in the production of other common everyday objects such as glasses, magnets, and televisions.
These elements are also widely used in the production of electric motors and batteries, which are used in hybrid and electric vehicles. Because of their low-carbon properties, they are regarded as an important component of the future of low-emission technologies.
