The Kennecott Flambeau Mine process documents provide researchers access to the documents that relate to the permit process for the mine. Approximately 25 documents describe the mine and its natural and cultural environments. The documents contain numerous color maps and illustrations. Access to approx. 130 drawings from a series of original blueprints will be available in the near future.
All the materials in this collection were made available to the citizens of Wisconsin at the Ladysmith Public Library during the life of the mine. They were donated to the Kurt F. Wendt Library, University of Wisconsin-Madison after the mine closed. Wendt Library holds the print copies.
This summary of the history of the mine and the permit process is based on the website "Reclaimed Flambeau Mine" by the Wisconsin Department of Natural.
Beginning in 1974, Kennecott Minerals Company initiated the process to obtain a mining permit in accordance with the newly adopted Metallic Mining Reclamation Act. The project as proposed in the mid-1970s involved mining the ore body in two phases, an 11-year open pit phase followed by an 11-year underground mining operation.
Flambeau Mining Company, a subsidiary of Kennecott Minerals Company, formally restarted the permitting process for the project in 1987, starting a three year process of baseline data gathering, negotiations with local communities, and project design and review.
The Wisconsin Department of Natural Resources issued the Final Environmental Impact Statement for the project in early 1990 and the permit hearing was held during the summer. The independent hearing examiner issued all necessary permits in January 1991 and construction of the project site began in July 1991.
Ore shipments from the site began in May 1993 and continued for just over 4 years. Backfilling of the pit took about 1.5 years and reclamation activities at the site were generally completed by the end of 1999.
The 181-acre mining site located about one mile south of Ladysmith, Wisconsin, is bounded on the east by State Highway 27 and on the west by the Flambeau River.
The Flambeau deposit existed at very shallow depth. Depth to bedrock at the mining site ranged from about 15-40 feet. Glacial sand, gravel and till overlaid sporadically occurring Cambrian sandstone which in turn sat above the weathered pre-Cambrian metamorphic rocks containing the Flambeau deposit.
Mining of this shallow ore body was accomplished through a 32-acre open pit. The pit trended in a northeast-southwest direction and was 2,600 feet long, about 550 feet in width, and reached an ultimate depth of about 220 feet.
Over the course of the mining operation, about 1.9 million tons of ore containing about 8.9% copper and 0.10 ounces of gold per ton were mined and shipped from the site. The mine produced about 178,000 tons of marketable copper and 328,000 ounces of gold.
The approved Reclamation Plan for the Flambeau Project specified that the open pit, upon completion of mining, would be completely backfilled with original rock material that was separated from the ore (waste rock and glacial overburden). Reclamation of the pit began in early 1997 and was completed in late 1998.

Western miners are beginning to process their metals in Africa in an effort to create supply chains for electric-vehicle batteries that bypass China. China currently dominates the production and processing of critical minerals like cobalt and lithium, which are crucial for the energy transition. This has raised concerns among Western governments about their dependence on Beijing. Despite the risks associated with operating in Africa, Western companies and investors are increasingly willing to build processing plants on the continent. These investments not only address the demand for local processing from African governments but also provide an alternative to China for Western auto manufacturers.
One example is Australian mining giant BHP Group, which has invested $100 million in a nickel mine in Tanzania and plans to build a processing plant in the country. This facility, expected to be the first of its kind in Africa, will produce battery-grade nickel for the US and global market by 2026. The trend of investing in processing facilities in Africa is likely to continue due to the growing demand for battery metals and China’s current dominance in the industry. London-based fund Vision Blue Resources has invested in a graphite mine in Madagascar and a processing facility in Mauritius, both of which are touted as the first of their kind outside of China. The company is also backing a cobalt refinery in Zambia, which is set to become the world’s third-largest and the largest outside of China. Western companies are willing to pay a premium for materials that meet environmental and labor standards, are traceable, and are produced outside of China. Despite the challenges, many Westerners believe the opportunities in Africa outweigh the risks, as they seek non-Chinese sources of battery metals.
Pressure on Western Miners to Process Metals in Africa as China Dominates Battery Supply Chain
Western miners are facing increasing pressure to establish supply chains for electric-vehicle (EV) batteries that bypass China, as Beijing dominates both the production and processing of critical minerals such as cobalt and lithium. This dependence on China has raised concerns among Western governments, prompting some companies and investors to build processing plants in Africa. By processing the raw materials they mine on the continent locally, these companies can export the refined materials directly to Europe and the U.S. This move also aligns with the demands of African governments for more local processing of metals and minerals extracted from their soil.
Australian mining giant BHP Group has invested $100 million in a nickel mine in Tanzania, along with U.S.-based Lifezone Metals. The companies plan to build a processing plant in Tanzania, which will be the first of its kind in Africa. The plant is expected to deliver battery-grade nickel to the global market, including the U.S., by 2026. London-based investment fund Vision Blue Resources has also invested in a new graphite mine in Madagascar and a processing facility in Mauritius. The company aims to establish the first graphite processing facility outside of China. Additionally, Vision Blue is backing a cobalt refinery in Zambia, which is expected to be the world’s third-largest and the largest outside of China once completed.
According to Jacques Nel, head of Africa Macro at Oxford Economics Africa, investments in processing facilities in Africa are likely to increase due to the expected boom in demand for battery metals and China’s current dominance in the industry. Western companies are willing to pay a premium for materials that meet certain environmental and labor standards and are traceable, as long as they are produced outside of China. This presents an opportunity for African countries to become alternative suppliers to Western auto manufacturers and other green-tech manufacturers in Europe and the U.S.
Despite the growing interest from investors, there are significant challenges for companies doing business in Africa. Some countries, such as the Democratic Republic of Congo, Guinea, Namibia, and Zimbabwe, have implemented resource nationalism policies, seeking a larger share of mining companies’ revenue. Zimbabwe, for example, banned the export of raw lithium, forcing foreign companies to process it within the country. Chinese competitors also have an advantage due to their established presence and appetite for risk in Africa.
However, many Western companies believe that the opportunity in Africa outweighs the risks. Chris Moorman, Chief Commercial Officer at U.S.-based refiner ReElement Technologies, stated that doing business in Africa is not as daunting as some people believe. The company recently signed an offtake agreement to process lithium mined in South Africa and is building a processing facility in the country. They are in talks with four Western automotive manufacturers interested in purchasing African-sourced lithium. This shift in attitude reflects the growing demand for non-Chinese sources of battery metals.
In conclusion, the pressure to establish supply chains for EV batteries that bypass China is leading Western miners to build processing plants in Africa. By refining the raw materials they mine on the continent locally, these companies can export the refined metals directly to Europe and the U.S. Despite the challenges and risks associated with doing business in Africa, Western companies are increasingly willing to invest in the region. This trend is driven by the expected boom in demand for battery metals and the desire for alternative suppliers to China in the Western world.

Platinum production at Shurugwi based mine, Unki declined by 16 percent to 35 700 ounces in the first half of 2020 from 42 400 ounces recorded in the comparable period last year. In the same vein, second quarter production was down 40 percent to 13 900oz from 23 100oz in prior period last year.
The Anglo American (Amplats) owned platinum producer mine, is one of the country’s three platinum producers in Zimbabwe, along with Zimplats and Mimosa Mine. The southern African country, is home to the world’s second biggest known deposits of platinum after South Africa.
Palladium production at the mine fell 16 percent to 31 700oz year to date from 37 900oz previously. In Q2 2020, palladium production went down by 42 percent to 12 100oz from 20 900oz in the comparable period.
The mine, previously, warned that conditions required for miners to reopen operations at the start of Q2 2020 will have a negative effect on production. Zimbabwe government allowed mines to restart full production, provided they first conduct mass testing of staff and confine workers to mine accommodation. Also, miners are required to observe social-distancing, which could slow production.
“Covid-19 lockdowns across southern Africa affected De Beers, PGMs, Kumba and Thermal Coal, with lower refined PGMs production due to the repairs and ramp-up of the ACP,” said Amplats in its latest production report.
In 2019, Unki commissioned a US$62 million smelter, which now processes platinum matte for Amplats’s base metals refineries.

Elkhorn Goldfields has four known deposits: Golden Dream, East Butte, Gold Hill, and Carmody. Since acquiring the property in 2000, we have focused our analysis, design, planning, and permitting efforts on Golden Dream.
An internal feasibility study of Golden Dream conducted by our staff engineers indicates probable underground mineral reserves of 1.17M tons containing 258,000 oz. of gold and 8.5M lbs of copper. Following successful production start up at Golden Dream, we will expand our focus to other deposits in the immediate area with the objective of bringing additional deposits into additional production.
In November 2011, we posted the $591,474 Reclamation Bond and the Montana Department of Environmental Quality (“MDEQ”) approved the Golden Dream Operating Permit (#00173). Golden Dream is now fully permitted and bonded for mining operations between 500 and 1,000 tons a day.
As of April 2013, we have developed 650 feet of a 14’ X 14’ main underground access tunnel and 350 feet of a 12’ X 12’ underground ore access tunnel. In Q3 2012, we completed underground and surface water treatment and disposal infrastructure necessitated by our Operating Permit. The main underground access ramp will be used to transport mined ore to the surface. Ore will then be transported by road to the Mill Complex at Montana Tunnels for concentration; concentrated ores will be sold and shipped to a smelter.
Our initial production plan targets the main pyrrhotite zone. Beginning in Q3 2013, we plan to extend the Golden Dream primary access ramp to reach deeper ore zones. A “bore” raise will be completed from surface into the main access ramp as a secondary egress. We expect to achieve initial ore production by Q4 2013 and full production by Q2 2014. Concurrent with development, the Mill Complex at Montana Tunnels will be re-commissioned to allow for processing ore shipments. We anticipate production of 55,000 oz. of gold in Year One.
We believe that Golden Dream mine life could be extended beyond ten years at anticipated peak production levels. We have identified an additional 250K oz. on the current mine level and drill intercepts suggest ore grade mineralization to depths of 1,200 feet below the surface (the current Golden Dream Plan extends to a depth of approximately 850 feet below the surface).
$30M of prior exploration data will guide future mining programs across Elkhorn Goldfield. The Elkhorn property consists of a collection of patented and unpatented mineral claims totaling approximately 4,500 acres. Our team and the property’s previous owners have completed drilling on an array of sites across the Elkhorn Goldfield, including:
- East Butte: 55,000 oz. of probable gold.
- Gold Hill: 75,000 oz. of probable gold.
- Carmody: 45,000 oz. of probable gold.
- Additional Inferred Resources: 1,191,000 oz. of gold equivalents.

Padež pri Laškem
Nmv: 510 m
Osnivanje rudnika : 1763.g
max. dubina okna: 264 m
Status: neaktivan od 1967.g
The abandoned lead and silver mine Padež is located east of Laško in a forest stretching above the Slapšak or, as locally called, Povh Farm . The currently known historical written sources do not specify in what period the Padež Mine was active, but it is believed to be in the Middle Ages. A military map from 1763-1767 shows Padež, but contains no indication of mining activity. Furthermore, the Mine is not mentioned in the Mining Manual of the Austrian Empire, which was issued from 1838 to 1861. Hence, the Mine is mentioned merely in Zollikofer’s records of the time he visited these places . Furthermore, expert institutions do not dispose with archival photography that would directly and credibly show the Mine operations and therewith related mining lifestyle in recent period.
Geologically, the Padež ore deposit is found in Carboniferous rock and represents one of the lead ore deposits in the region of the Posavje Folds. It falls within the group of lead and zinc lode ore deposits strung between the Ljubljana basin in the west and Laško and Sevnica in the east, none of which, however, is currently in operation.
Today, access is provided to some 264 metres of pits in the Padež Mine. The primary ventilation and exploration shaft with an entrance at an altitude of 510m is 113m long . In the north, i.e. the left side of the ventilation and exploration shaft, two side exploration shafts branch off at 50 and 78 metres from the entry, with raises and inclines to faces No. I, II and III. In the side exploration and ventilation shaft 50m away from the entry to the primary shaft, there are two, floor and ceiling, intakes 25 and 30m from the primary shaft. The total length of accessible shafts, raises and inclines to faces I, II and III, which are located north of the primary shaft, amounts to 139m. In the south, i.e. the left side of the primary shaft, there is a 12-metre-long side exploration shaft some 50m away from the entry.
The ore-bearing rock is micaceous-quartz sandstone with intercalations of feldspar and siltstone like in the Sitarjevec Mine. Mineralisation occurred as a result of tectonic movements that caused quartz sandstone to crack, thus allowing the penetration of hydrothermal solutions enriched with ore minerals and silica into the cracks. There is a thick bed of quartz conglomerate amidst the ore-bearing quartz sandstone, with slate, feldspar and siltstone beneath it. There is no mineralisation phenomenon in the beds of quartz conglomerate, shale, feldspar and siltstone, which is why they are considered to be spoil section of the ore deposit. Based on geologic mapping of the surroundings of the Padež Mine, it was established that there are beds of slate, feldspar and siltstone under quartz sandstone in the area of the planned educational forest trail, which are covered by a bed of quartz conglomerate representing the hanging wall of ore-bearing beds like in other lead and zinc deposits in the Posavje Folds (Figure 4).
The preserved technical documents on similar ore deposits of such type reveal that veins were several centimetres to 2 metres thick, whereby primary veins exceeding the thickness of 0.3m were exploited. The main ore minerals emerging in the veins were galenite, sphalerite and tetrahedrite with accompanying minerals, such as pyrite (iron ore mineral), chalcopyrite (cooper ore mineral), cinnabar (mercury mineral), elementary mercury and baryte. Production was generally low in terms of quantity and irregular, and most ore was extracted from the Sitarjevec Mine near Litija, where no more than 3,200 tonnes of lead and 2,000 tonnes of silver were extracted from some 20,000 tonnes of ore at the best of times.
Inspections of accessible shafts and the surface above the Mine revealed that geological conditions and mineralisation at the Padež Mine were similar to those identified in the other Carboniferous lead and zinc deposits in the Posavje Folds. All shafts on the map were excavated from micaceous-quartz sandstone with siltstone intercalations. No vein mineralisation was identified in the micaceous-quartz sandstone at the examined faces I, II and III on the macro and micro level, but it may be assumed that thicker veins were exploited at lower levels than those accessible today.
Walls and ceilings of abandoned shafts were frequently lined with secondary ore minerals, such as epsomite, aragonite and calcite, which represent a wealth of natural resources at the Padež Mine. Crystals of epsomite, known as hydrated magnesium sulphate or bitter salt, emerge in the form of white tuberous aggregates, which can be found at the Padež Mine most often in the entry shaft (Figure 5). Deeper in the Mine on the rims of shafts, there are frequent branching aragonite special stalactite shapes, scallops, stalagmites and stalactites, and short flowstone draperies (Figure 6) (Majcen & Golež, 2010). There is also beautiful fauna in the Padež Mine (Figure 7).
A geological pillar was erected in front of the entry to the ancient Mine with the rocks used for building in and around Laško Municipality (Figure 8). Next to the pillar, there is an information board explaining the type, age and structure of the mentioned rocks. With the arrangement of the Mine for the purposes of tourism, natural resources at the Padež Mine were mostly physically secured with a fence that prevents their further destruction while allowing an uninterrupted process of their development into forms not yet known.
Most lead mines in the Posavje Folds were abandoned at the beginning of the 19th century. Exploitation at Padež most likely also ended at that time. Mine shafts hence gained a new meaning that can only be properly evaluated today, particularly through the contribution of the work invested by former miners. The abandoned shafts bear an impression of human labour, friendship and solidarity, i.e. rich intangible heritage that is transferred to today’s visitors to the Padež Mine. It touches each one in its own way, i.e. through research work, DNA of miners’ descendants, memories of cleaning collapsed shafts, hanging out in galleries and chatting with the Mine caretaker, on a walk along the educational forest trail or merely by looking at the photos taken upon a visit to the Mine.


Silver-toned is a metal with a variety of applications. It is technically classified as a precious metal, but it has many industrial uses and is used in a disparity of technologies and products that most people in the developed world use on a daily basis. In 2020, silver production go pasted down globally to 25,000 tons versus 26,500 tons in 2019. Below are the top global rankings of silver production by surroundings, based on estimated data by the US Geological Survey.
10. United States
Ranked tenth on the list of top silver-producing countries is the Common States. In 2019, it produced 980 metric tons of the metal, mainly from three dedicated silver searches and nearly 40 other base and precious metal mining operations around the country. The two top silver-producing states are Alaska and Nevada.
With lustrous production at 1,200 metric tons in 2019, Argentina ties with Bolivia for the crowded ninth-spot on this enumerate. Last year saw its silver production increase by 17.6%. The total silver reserves for the country were not determined.
The South American political entity of Bolivia ranks ninth on the list, tying with border country Argentina. It produced 1,200 metric tons of silver-tongued in 2019, a little more than its 2018 production of 1,190 metric tons. The country has many silver depositories, especially the Cerro Rico de Potosí which is estimated to still have large deposits of silver inside. The San Cristobal depository in Bolivia has the third-largest silver deposits of any single mine in the world.
Chile produced 1,300 metric tons in 2019, up from 1,370 metric tons in 2018. Chile is comparable in size to Texas and has an assessed 27,000 metric tons of silver reserves.
Australia is a country that has held relatively stable dulcet production levels. The country produced 1,400 metric tons of silver in 2019, although it has the third-largest silver hoards after Peru and Poland. Australia is about 80% of the size of the United States.
Poland produced 1,700 metric tons of greyish in 2019, up about 15% from 2018. Poland holds a unique place in the silver markets: despite being a humble country the size of New Mexico, it has large silver reserves of 100,000 metric tons.
Russia, twice as obese as the United States, produced the fourth-largest amount of silver. Russia’s silver production remained stable from 2018 to 2019, breeding 2,100 metric tons. The total silver deposits of Russia are estimated at 45,000 metric tons.
In 2019, China produced 3,600 metric tons of burnished. Interestingly, 95% of China’s silver production is the byproduct of other mining operations. The country lost its second grade to Peru in 2016, and the country produces a little more than double the amount of silver that the U.S. does.
Peru has steadily ripened its silver production levels and has maintained its second-place ranking from 2018 to 2019. The South American nation beared 3,800 metric tons of silver in 2019, down from 4,160 metric tons in 2018 due to protester blockades and some woman strikes. While a small country, Peru is thought to have the world’s largest reserves of silver, with 120,000 be informed metric tons.
The number-one silver-producing country in the world is Mexico. In 2020, the country produced 5,600 metric tons versus 5,920 metric tons in 2019. Silvery production in Mexico is only expected to increase further.

Our ring mills deliver some of the most efficient crushing capabilities in the industry - effectively reducing a wide range of materials to uniform size.
Engineered Recycling Solution's ring mills deliver some of the most efficient crushing capabilities in the industry - effectively reducing a wide range of materials to uniform size. Each ring freely rotates on the shaft and is held in its outward position by centrifugal force. This process reduces by impact rather than sharpness and is free to deflect from tramp metal. Rings are reversible for double wear and can be installed in a staggered formation covering the entire width of the crushing chamber. A heat-treated steel main shaft revolves in heavy-duty anti-friction bearings, which are enclosed in dust- and air-tight pillow blocks.

Thanks for your compliments everyone. Bruce is correct, checked further this is not the Carolin Mine, but the much older Emancipation Mine with some rich history.
In 1910, during the construction of the Kettle Valley railway (now abandoned) along the Coquihalla River valley, prospectors exploring the valley and its tributaries for gold found several gold prospects. Between 1913 and 1915, the Emancipation claims plus other adjoining claims were staked by Messrs. M. Merrick, Wm. Thompson and H. Beech to cover gold-bearing quartz veins. Since the discovery, the claims have experienced sporadic exploration and mining activity. During the early life of the Emancipation mine, from 1916 to 1919, some 95 tons of ore was extracted, and returned over $35,000 (averaging 15 oz/ton). By 1921, considerable amounts of underground development work had been carried out and a five-stamp mill installed with a production capacity of 12 tons per day. The operator was the Liberator Mining Company of Vancouver, B.C. During this period, approximately 118 tons of ore was shipped to Tacoma, Washington, USA, again with a return of approximately $35,000 and an additional 700 tones of sub-ore valued at $15.00 per ton was stockpiled at the mill. Work at the mine was intermittent from 1922 through to 1933, during which time the property changed owners several times with Dawson Gold Mines Ltd. being the major operator. Limited work was done in 1937 by Kettle Valley Gold Mine Ltd. As documented by the B.C. Department of Mines, production figures between 1916 and 1941 from the Emancipation were 2,897 oz. gold and 605 oz. silver; total tons of ore mined is unknown. From consideration of the volumes of drift and stoped ground in the underground workings, material produced has been possibly about 10,000 tons. The substantial waste dump at the No. 2 Portal indicates that only a part of production was considered mill fee.
The 1933 Minister of Mines report provides some interesting but limited information regarding the lower tunnel (4 Level) which until 1991 was inaccessible due to sloughing of overburden at the portal. It is described as 210 feet below No. 2 Level. During 1933, the drift was driven 570 feet with cross-cuts at intervals to east and west with the face at that time nearly directly under the ore body in No. 2 winze. The face at that time (1933) of the drift showed a vein zone of about 11 feet wide with intercalated country rock and some calcite. The central part was well mineralized with sulfides. Chip sample over 8 feet assayed 0.40 oz./ton in gold and 0.10 oz./ton in silver. A picked sampled from the face at that time assayed 2.12 oz./ton in gold. Observations in 1992 suggest that this mineralized area appears to pinch out a short distance to the north along the drift. At that time, ore was being produced from stoping on No. 2 Level and this material was being transported to the mill lower down by the aerial tram. The mill operated at 25 tons per day. Operations by Dawson Consolidated Ltd. continued at least to 1938 but no quantities or grades of production during the latter part of the operation are preserved.
In recent years (1971 and later) due to the increase in price of gold, the Emancipation Mine and adjoining claims experienced renewed exploration. In 1971, Aquarius Resources Ltd. acquired the existing claims and mineral leases (Sunshine and Raymond) and with additional staking, the claims were collectively called the Hope Group. In 1972, A. R. Bullis surveyed, mapped and sampled the underground workings in the Emancipation mine and Dr. G. C. Stephens of Alrae Engineering in 1973 conducted general surface geological mapping on the entire Hope Group. From 1976-79, under the direction of Cochrane Consultants Ltd., an extensive surface exploration program on the claims was carried out which included detailed geochemical soil surveys and ground geophysical work. In 1980, an all-weather road was constructed to the Emancipation Mine and further underground mapping and sampling was performed by in-house Aquarius staff under the direction of D. Cardinal, The following season (1981), an aggressive surface and underground diamond-drilling program was conducted. Results from the drilling program were encouraging and demonstrated the need for continued underground exploratory drilling. However, no further work was conducted until the underground diamond drilling by Homegold Resources Ltd. in 1991-1992 under option from Anglo Swiss Mining Corp.
The work conducted on the Emancipation Mine commenced by Homegold Resources Ltd. during the fall of 1991 with the reopening of the 1.6 km access roads constructed by Aquarius Resources Ltd. in 1980. The roads were overgrown with dense alder trees and brush. An excavator and D8 bulldozer were used to repair and ditch the roads and excavate sloughed material that had covered the 4 Level portal of the Emancipation Mine. A new access road was constructed ramping down from the 3 Level portal to the newly reopened 4 Level portal. The portal was re-timbered, washed out and the 4 Level drift was scaled. Upon completion of the scaling, the drift floor was mucked out, the major obstacle being material from the raise up to 3 Level that had flowed into 4 Level. The narrow gauge (18 inch) track was repaired. A small ore car was set on the tracks and was used to carry the cave material out of the drift. Once the drift was cleaned up, drill stations were established by slashing out openings along the cross-cut and drift walls.
The drill program was designed to explore a possible replacement zone that had been intersected by Aquarius Resources Ltd. in the down-dip extension of the "Boulder" vein. Underground diamond drilling in 1980 and 1981 indicated that sulfide and silica replacement increased with depth and along strike below the 3 Level on the Boulder and subsidiary veins.
The underground workings were surveyed by transit and EDM (S. Nickel and Associates Surveying Ltd.) and accurate plans and sections prepared. A total of 3 holes were drilled in 1991-1992 for 267 feet of core. The mineralized intervals were split and assayed at Chemex Labs Ltd. In 1994, the area around the portals was prospected and the 1991-92 underground core was logged.

Extracted and alternative raw materials
Cement production consumes significant amount of raw materials, like limestone, clay, marl, sand, iron oxide, bauxite. Raw material conservation is part of TITAN’s determination to work towards sustainability. Investing in the use of alternative raw materials can serve this need in two ways, firstly, by reducing the consumption of extracted raw materials and secondly, by reducing the amounts of by-products that had to be landfilled, giving the society win-win solutions.
In 2011, the Group used 18.6 million tons (dry basis) of raw materials for cement production. Approximately 6.6% of all raw materials (about 1.2 million tons - dry basis) were alternative raw materials, namely by-products and waste disposals from other industries such as fly ash, pyrite ash, blast furnace slag and industrial gypsum. The remaining 17.4 million tons (dry basis) were natural materials from mining and quarrying activities.
Compared to 2010, the consumption of alternative raw materials, as quantity as well as percentage of the total raw material consumed, has been improved due to the effort made to increase such use by most of the Group’s facilities. More specific, last year the quantity of alternative raw materials used was increased by almost 8%, while in respect to 2003 the relevant increase was almost 34%.

Can you find gold in coal?
gold is not uncommon in coal deposits, most coal deposits contain gold above average crustal abundance. In fact, many gold mines recover gold using heap leach technology.


While mine disasters dominate news headlines, mine workers face a subtle killer in the form of black lung disease, which contributes to the deaths of over 700 U.S. coal miners annually.
The National Institute for Occupational Safety and Health (NIOSH) Office of Mine Safety and Health Research (OMSHR) was tasked with developing improved dust monitoring technology to advance the protection of miners from respirable dust that causes black lung.
A key innovation to this effort’s success was the partnership that NIOSH formed with labor, industry, manufacturers, and regulators to develop a continuous personal dust monitor (PDM). As a capstone to this partnership, the personal dust monitor, PDM-3600, was commercialized in 2009. To date, over 200 units have been sold to mining companies, with new government regulations for dust control now requiring the use of this technology.
With NIOSH providing scientific leadership, the other partners contributed their experience and expertise. This partnership, formed in the developmental stages of the work, resulted in substantial stakeholder buy-in and an effective final product.

An overview of the process of treating AMD at LWA's Upper Latrobe AMD Treatment System, located in Latrobe, PA
Fixing Mistakes of the Past Through New Treatment Techniques
A priority project area for LWA since our inception has been constructing innovating treatment systems to tackle one of the largest sources of pollution to our area's waterways - Abandoned Mine Drainage. "AMD", as it is commonly known, contributes tons of iron and other heavy metals into streams within the Loyalhanna Creek Watershed, and most of Pennsylvania. The result of AMD pollution can be seen in orange, white or even black water that is both unattractive, as well as uninhabitable for aquatic life.
The metals and other contaminates contained in this water stem from ground water that has passed through sections of underground deep coal mines that were abandoned without proper remediation measures in place. Most of the coal mining activity within our watershed occurred in the late 1800's and early 1900's when no guidelines were in place to handle any pollution sources that might have occurred as a result of this activity. It has become a focal point of our association, as well as other conservation organizations, to address this pollution source by constructing treatment systems to clean up this water before it enters our area waterways.
Josh Penatzer, LWA Project Manager, takes us around the site of the Upper Latrobe Mine Drainage Treatment System in this video segment, and explains the process of passive mine drainage treatment at work at this site.


VANCOUVER, BC / ACCESSWIRE / May 11, 2022 / CMC Metals Ltd. (TSXV:CMB)(Frankfurt:ZM5P)(OTC PINK:CMCXF) ('CMC' or the 'Company') is pleased to announce significant targets have been identified on its Silverknife property as a result of a recent geophysical interpretation completed by Intelligent Exploration ('IE'). Dr. Chris Hale and Mr. John Gilliatt have recently completed an interpretation of geophysical data of the electromagnetic and magnetic airborne geophysical survey completed by SkyTEM Canada Inc. on the property in 2021. The silver-lead-zinc Silverknife Prospect is located within the emerging Rancheria Silver District that extends from south-central Yukon into Northern British Columbia and hosts the Silvertip Mine owned by Coeur Mining Inc. Silvertip is one of the highest-grade underground silver-lead-zinc mines in the world.
IE noted that the Total Magnetic Intensity ('TMI') on the Silverknife claims (See Figure 1) shows TMI highs indicating more magnetic intrusive rocks (Cassiar granodiorite) and broad areas of comparatively non-magnetic sedimentary rocks including limestones and dolomites that potentially could host a carbonate replacement (CRD) style deposit similar to the neighboring Silvertip Mine and CMC's Amy Prospect approximately 8km west of Silverknife. The TMI data also show that the intrusive is more extensive than previously recognized and its proximity to the McDame Formation and Tapioca Formation limestones offer good potential for them to host a CRD style deposit.Figure 1. Total Magnetic Intensity ('TMI') on the Silverknife claims.
In total, six targets were identified at Silverknife (see attached figure 2). Three targets are located in the northwestern portion of the property and are newly discovered anomalies. These anomalies appear to follow the contact of the Cassiar Batholithic rocks with sedimentary sequences believed to be associated with the River Road and Tapioca Formations.Figure 2. The Six SkyTEM targets identified at Silverknife.
The remaining three targets in the south-central portion of the Property occur close to previously identified geochemical anomalies located on a downslope and appears to form at the contact of a magnetic and resistive body, possibly indicating skarn mineralization. The anomaly is considered to be at shallow depth and therefore mapping and possible trenching of these conductors has been recommended.
The Company is also noting that the prospectivity of the Silverknife Property has been elevated by recent news from Coeur Mining Inc. (Coeur Mining Press release, April 28, 2022) on their exploration of the Silvertip Mine Claims where a new zone called Camp Creek West was recently discovered. This zone is located west of the Camp Creek Fault and remains open to the west, north and south. It extends known mineralization toward the Silverknife claims.
Mr. John Bossio, Chairperson noted, 'We are extremely excited about these new developments on our Silverknife Prospect and Coeur Mining's new Camp Creek West discovery. We are now working to accelerate exploration efforts on Silverknife this summer.'
Mr. Kevin Brewer, President and CEO stated: 'From historical exploration, we thought there was potential for additional targets in the northern portion of the Property, and it is exciting that this has now been verified by the SkyTEM survey. The additional targets in the south-central portion of the Property coincide with previously known geochemical targets. This strengthens our belief that CRD style targets like Silvertip, that typically form in clusters, may exist on our Silverknife claims. Plans are underway to undertake a gravity geophysical survey on the northern targets and a detailed mapping, prospecting and/or trenching program on the south-central targets.'

The ferromanganese refers iron alloy of manganese and iron. Major categories: high-carbon ferromanganese (carbon-containing 7%), medium carbon ferromanganese (the carbonaceous 1.0 to 1.5%), and low-carbon ferromanganese (0.5% carbon), manganese powder, mirror, iron, silicon manganese alloy.
Used as a deoxidizer and alloy additives in steelmaking, is the largest amount of ferroalloys. The manganese use for melting
ferromanganese, general require ferromanganese content manganese from 30 to 40%, manganese and iron ratio is greater than 7, and phosphorus and Mn ratio is less than 0.003.
Smelting manganese carbonate before the first block to be made by sintering after roasting. High phosphorus and iron ore is generally only used proper proportions or through the selective reduction of refining low iron phosphorus manganese-rich slag.
Carbon ferromanganese in international standard is content 75 to 80% of manganese, to adapt to the low grade manganese ore raw materials, china provisions manganese lower grades (electric furnace ferromanganese more than 65% of manganese, blast furnace ferromanganese manganese more than 50%).
Carbon ferromanganese smelting blast furnace in the past, with the development of the electric power industry, electric furnace was gradually increased.
According to metal powder supplier, blast furnace smelting generally use less than 1000 m 3 blast furnace, equipment and production process is
generally the same as the blast furnace.
In the process of falling from the roof, the high prices of manganese oxide (MnO2, Mn2O3, Mn3O4) with increasing temperature, gradually restored to MnO by CO, but MnO only direct reduction into a metal by carbon at high temperatures, so smelting ferromanganese requires a higher temperature of the furnace hearth, this refining ferromanganese blast furnace using a high coke ratio (1600 kg / ton) and air temperature (1000 above).
To reduce the manganese loss, the slag should be maintained high basicity (CaO/SiO2 greater than 1.3). Due to the coke rate high and low indirect reduction, yield refined ferromanganese blast furnace gas containing CO than the blast furnace, roof higher temperature (350 ).
Oxygen enriched blast can increase the temperature of the hearth, lower coke rate, increase production, and due to the decrease in gas volume can reduce the roof temperature, a significant role in the improvement of ferromanganese smelting.
The reduction smelting of ferromanganese have
flux method (also known as low the manganese slag law) and no flux method (high manganese slag) two kinds. Flux method principle is the same as blast-furnace process, just electricity instead of heating coke in blast furnace.
Through add lime to form a high basicity slag (CaO/SiO2 1.3 to 1.6) to reduce the loss of manganese. Flux method smelting lime to form alkalinity is lower (CaO/SiO2 less than 1.0), with high manganeses low iron low phosphorus manganese-rich slag.
This method is less slag, reduce power consumption, and because of the lower slag temperature can reduce manganese evaporationloss, and the byproducts manganese-rich slag (25 to 40% manganese) can be used as raw material for smelting manganese silicon alloy to achieve a higher manganese recovery (90%).
Manganese silicon alloy use a closed or semi-closed reduction smelting furnace. Generally use containing silica, phosphorus, manganese or another with the addition of silica as raw materials.
Manganese-rich slag containing high silica is a good raw material for smelting manganese silicon alloy containing phosphorus.
Smelting consumption generally about 3500 to 5000 kW / ton. The furnace raw material first for pre-treatment, including whole, warm-up, pre-reduction and powder sintering, significant improved the electric furnace operation and technical economic indicators.
The high basicity slag can make the
manganese reduced in the slag, reduce the manganese loss caused by the spoil.
Charge preheating or loaded liquid manganese silicon alloy helps shorten the refining time and reduce power consumption.
Medium and low carbon ferromanganese also through liquid silicon manganese alloy, manganese ore and lime
melt mixing each other to produce.
