The need to reduce the extraction of key minerals abroad
How long can the United States rely on troubled South American nations for two critical metals—lithium and copper—that are essential to our national security and transition to a green economy?
Answer: We really don’t know. But now we need guarantees because we are in a precarious position. Chinese companies have bought some of the best mines in South America, highlighting the fragility of supply chains in our country.
Four countries with a history of political instability and instability – Argentina, Bolivia, Peru and Chile – hold some of the richest lithium and copper deposits in the world. Lithium is a key component of lithium-ion batteries for electric vehicles, as well as wind and solar energy. Copper has many applications in weapons systems, consumer products, and clean energy technologies.
Growing global demand for these battery metals has led to a reduction in supply and higher prices for lithium and copper. While most of the mining takes place in South America, Chinese companies send raw materials to China for processing before they are sold on the international market. Today, China controls more than half of the world’s lithium production, having invested $4.2 billion in lithium mining in Argentina and Chile since 2017.
Unfortunately, the reality is that imports cover more than 50% of US consumption for 51 minerals, and we are 100% dependent on imports for 15 of them, according to the US Geological Survey. More than half of the minerals and metals on which the US depends for advanced technologies, such as rare earths, come from China. Half of the uranium used in US nuclear power plants is imported from Russia, Kazakhstan and Uzbekistan.
The United States needs to address the lingering damage caused by the nation’s long-term decline in mining production and its growing reliance on imported minerals and metals. Dependence on copper imports is of particular concern because it is an electrification metal essential for the energy transition. The World Bank expects global demand for copper to grow by 1000% by 2050. A study by S&P Global warns that the goal of reaching zero carbon emissions by then will remain elusive unless significant new copper supplies arrive soon.
Geologists say there are many deposits of lithium and copper underground in the US. Just one potential copper mine in Arizona could supply a quarter of the country’s needs within decades.
For years, the United States has depended on other countries for the metals and minerals that the country could mine at home, if only potential investors were discouraged by a permitting process that is so cluttered with bureaucratic procedures and overlapping state and federal requirements that an average of 17 years from the idea of a new mine to the start of its operation.
Without a doubt, major changes to our nation’s supply chains will be required to ensure a mineral security that is not overly dependent on imports from adversaries or countries with entrenched political dysfunction. Now is the time for government action, with a focus on improving the US mining permit process in a way that leads to more mines in the country and less dependence on battery metal imports.
Experts say the US has the resources, know-how and mining technology to ramp up production quickly. We need national commitment. President Joe Biden and the new Congress must embark on a realistic plan to reorient the mining industry that recognizes that other countries, such as Canada and Australia, with environmental standards comparable to our own, are issuing mining permits twice as fast as the US. unless we produce metals. such as lithium and copper on a large scale, the United States will increasingly depend on imports of minerals and metals for batteries from China and other distant and unreliable countries.
China has used its power over vital minerals to pressure other countries, as in 2010 when China blocked exports of rare earths to Japan during a fishing trawler incident, causing world prices to soar. And during tense trade negotiations, China threatened to block exports of minerals to the US.
One more thing: China may decide to dedicate more metals and minerals to batteries to meet its own electric vehicle manufacturing needs rather than export the materials to the United States. This creates the possibility of significant cost increases for US automakers if problems get out of hand.
If we care about our heavy dependence on imports, if we care about protecting our society from major economic shocks, we need to start taking steps to reduce our imports of battery metals and focus more on mining here at home.

Governor Ademola Adeleke says his administration will ensure mining and gold companies pay their debts to Osun.
Mr Adeleke disclosed this on the sideline of the inauguration of the solid mineral sector committee in Osogbo.
He said Osun had no record of any payment made by Segilola and other mining companies.
The governor on Monday, in a press statement through the secretary to the state government, Teslim Igbalaye, appointed Sola Adewumi as the chairman of the revenue committee and Samuel Ojedokun as chairman of the solid minerals committee.
“Osun, according to extant laws, is entitled to 13 per cent derivation from every ounce of gold extracted from our gold and other solid mineral fields. Segilola and other operating companies are expected by law to pay 13 per cent derivation on the value of gold and other solid minerals produced in the last 25 years,” the governor said.
The governor noted that the state had been subjected to intense environmental degradation from mining companies’ activities.
“River Osun has been polluted, and our people are dying, as related sicknesses are spreading. These are sad realities which none of the mining companies has raised a finger to address,” stated Mr Adeleke. “My administration will insist on the companies paying for the cleaning up of our rivers and environment.”
He explained that his administration would ensure that cleaning up the environment is a continuous exercise and mining companies would bear the cost.
The Osun governor added, “All state mining licences already diverted to private possession must be fully recovered, and illegal mining activities stopped. Also, illegal mining syndicates will be arrested and prosecuted.”

What are the uses of ultra-fine vertical grinding?
Ultra-fine vertical grinding has the effect of over-grinding. It can be used for grading, drying and dispersing of complete equipment. It can be combined with vertical mill to form pre-grinding, mixing grinding, semi-grinding, etc. Grinding and other new process complete process, due to the principle of
, the new grinding system process can reduce the grinding power consumption system by about 50%, the output can be improved a lot, can be applied to cement or raw materials and cooked In the material, the new grinding system is suitable for the grinding of a variety of mineral powders, thus solving the current situation of insufficient grinding capacity with the new standard. The grinding system has been widely used in many industries.
There are many models of ultra-fine vertical grinding. The fine ore fineness and high screening rate after ultra-fine vertical grinding process convey a large amount of production for refractory materials, cement, glass flux, building materials, paint, ceramics, chemical industry and other industrial parts. Good raw materials have improved the economic price of dolomite.
The fineness of the
can be adjusted during the grinding process. When processing different ores and crystal materials, in order to improve the production time of the grinding material, the production can be reduced by reducing the consumption, and the particle size is selected to be smaller than The powder below 1mm is directly into the grinding machine, and the remaining more than 1mm is re-extruded into the main machine, which greatly reduces the particle size of the slag, which shortens the grinding time and increases the output of the mill. The grinding process and equipment also need to be adjusted accordingly.

There are several processes that lead to mineral concentration in specific areas. For instance, volcanic activity causes minerals to concentrate in certain areas. As a result, the minerals in those areas are concentrated. Here are some examples of the processes involved in mineral concentration. One of the main reasons why minerals become concentrated in a particular area is because of the location where they were deposited. This process can occur in any area.
Streams erode the rock and deposit sediments on stream banks. These deposits are known as alluvial fans. Waves erode sediments in the ocean. Winds can pick up clastic sediment and concentrate placer deposits. In either case, the particles are sorted based on size and density. In addition, larger sediments require more energy to stay aloft. For this reason, rivers and lakes are rich in certain minerals.
The most common process that causes minerals to become concentrated in certain areas is volcanic activity. This process is responsible for creating new minerals on the planet. Magma rises from the mantle and solidifies at the surface. As a result, it creates a much more acidic environment. This causes certain minerals to alter, and others to precipitate as new minerals in the pore space. These processes are important for mineral concentrations in different areas.
Another important process that leads to mineral concentration is hydrolysis. In this process, a chemical compound reacts with water. The water carries away the mineral’s ions. After the ions are carried away, the mineral has been dissolved. This process has also created travertine, a limestone deposit that forms in lakes, caves, and hot springs. These are all products of hydrolysis.
Whether a mineral is present on a particular area is a result of a process called evaporation. When water evaporates, the minerals are released into the earth’s crust. Some of these minerals are stable and not affected by water, while others are not. A mineral’s concentration is determined by its location. This is why they are concentrated in a particular region. Some mineral deposits are found in a specific region.
Another way minerals are concentrated in some areas is due to volcanic activity. As magma rises from the mantle, it begins to solidify. Some of this material settles on the surface, resulting in the concentration of minerals in the area. The remaining minerals remain in the area. These are considered’residues’ and are often called mineral ores. These deposit types are often found near volcanic activity.
There are many processes that cause minerals to be concentrated in specific areas. Most of the minerals that are found on the surface are concentrated due to volcanic activity. These are formed when magma rises from the mantle and then gradually solidifies. Other processes cause the minerals to form in specific areas. If these are the main reasons, why do minerals form in certain places? It is important to understand that they are created by volcanoes.
A mineral is a naturally occurring crystalline solid. It cannot be physically broken down into smaller parts. This makes it more valuable for mining. Moreover, it can lead to higher mineral concentrations. The mineral is therefore concentrated in a certain area, which can lead to increased productivity. The process can cause huge amounts of minerals to accumulate in a single spot. It may also lead to a more profitable business.
The next process in which minerals become concentrated is through the formation of new minerals. This is a complicated process that requires a lot of knowledge about different minerals. It is not surprising that the process used to create new minerals on the earth is complex. The elements that form a mineral may be separated into two or more different ions, though. It is also important to understand how these deposits are formed. It is vital to understand how they are formed.


You won't believe how much the giant stone is worth, say officials from Australian mining company Lucapa.
It may take the likes of James Bond himself to protect this flawless 404-carat diamond recently discovered in Angola. According to a report from ABC, the Lucapa Diamond Company, based in Perth, Australia has just discovered one of the biggest diamonds seen in recent history. The diamond is 404 carats and is worth an estimated $20 million or more.
The diamond was discovered at the Lulo Diamond Project in Angola’s northeastern province of Lunda Norte. It has taken the record of biggest diamond ever found within the country’s borders. The chairman of Lucapa, Miles Kennedy, said the discovery was a huge achievement.
“When we first looked at the property, 3,000 square kilometers of untouched ground, 700 kilometers inland from the coast, you are talking about a very, very remote area,” he said.
In addition to being the biggest diamond ever unearthed in Angola, the stone is also the largest diamond ever discovered by an Australian miner. Kennedy called the diamond ‘spectacular,’ and said that the stone was of excellent quality.
The diamond has caused valuation experts to scratch their heads, as it really is a one-of-a-kind gem. “We’re not used to valuing 400-carat diamonds, but if we look at other diamonds slightly less weight than this, you’re looking in the order of $20 million,” said Kennedy.
Kennedy has been working with diamonds for decades. He set up the Ellendale diamond mine in Australia’s northwestern Kimberley region in the 1990’s. After finding success on his home continent, Kennedy set up the Lucapa company by moving his mining and geology team to Angola. In fourteen years of digging in Australia, Kennedy never found a diamond larger than 10.8 carats. A diamond of this size is considered a “special diamond,” and since moving to Angola, the company has discovered more than 100 of them. He expects the sale of the massive stone to provide his company with enough cash to continue expanding and searching for more in the near future.
The diamond is currently the third largest diamond ever discovered in the world, coming in right after the 3,106-carat Cullinan diamond which was dug out of a mine in South Africa in 1905. A 1,111-carat diamond was also discovered in a Botswana mine last year by the company Lucara Diamond.
The stone measures about seven centers in diameter, or 2.75 inches. According to Endiama, Angola’s national diamond company, “It was a significant day for our country, our diamond industry and for the Lulo diamond project.”


Researchers help expand mineral exploration using machine learning
Curtin University researchers have developed a new system that will help identify undiscovered mineral deposits in Western Australia using an advanced machine learning tool.
As part of a research project in collaboration with the Geological Survey of Western Australia, geochemical data collected all over the State will be analyzed to reveal patterns in big data that are not possible to see with standard methods.
Lead researcher Dr. Vladimir Puzyrev, from Curtin University's Oil and Gas Innovation Centre and the School of Earth and Planetary Sciences, said researchers were using a machine learning technique called deep learning to help expand mineral exploration in Western Australia.
"Deep learning methods are completely transforming the landscape of data analysis because they achieve unprecedented performance levels across various tasks, significantly reducing the manual labor and subjectivity present in more conventional methods of exploration," Dr. Puzyrev said.
"The ultimate aim of this research project is to help identify new mineral deposits in Western Australia by analyzing big geochemical data using deep learning methods."
Researchers are analyzing the Geological Survey of Western Australia's Mineral Exploration database, WAMEX, which captures the State's exploration project activities over many years.
Geological Survey of Western Australia Project Lead and Senior Geologist Dr. Paul Duuring said the WAMEX database contained more than 50 million samples.
"There are time and cost challenges in the manual quality control of such large data, so this project is an important step towards adding value to existing digital geochemical datasets," Dr. Duuring said.
"An improved database opens new possibilities for Western Australia's mineral exploration sector."
Dr. Puzyrev said the project also offered additional potential applications including identifying the most cost-effective and innovative geochemical data analysis method for the treatment of samples.
"More generally, this research project also opens up potential new avenues for future research that will also benefit the State's mineral exploration sector," Dr. Puzyrev said.

Can I refine my own gold?
Simply put, the trick to refining gold is to dissolve impure gold in acid such that all the impurities fall out, and then to pull the pure gold back out of your acid solution..
How long does it take to refine gold?
This process can be as short as one year, or it can be as long as five years from the time of the mine discovery to the time when mining can begin.
At what temp does gold melt?
1,064 °CGold/Melting point
Will vinegar remove gold plating?
Since gold is electroplated or electrically bonded to silver, there are no chemicals or solvents that will readily remove gold plating. … Using white vinegar, sea salt, and hydrogen peroxide to recover gold foils from scrap computer circuit card fingers. Then bleach to dissolve and vitamin C to precipitate.
How do you remove impurities from gold?
Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away. The remaining substances will be just water and gold, the latter having a purity level of more than 99.99 percent.
How do you refine raw gold?
It is possible to refine gold without the use of large-scale, expensive chemical procedures. The process involves first adding nitric acid to gold, then adding hydrochloric or muriatic acid. After allowing this mixture to sit, it is filtered to remove contaminants, then treated to neutralize the acids in the solution.
How do you purify gold at home?
Pour 30 milliliters of nitric acid for every ounce of gold into your container. Allow the acid to react with the gold for 30 minutes. Add 120 milliliters of hydrochloric acid or muriatic acid for every ounce of gold in the container. Allow the solution to sit overnight until all of the acid fumes have been dispelled.
How much gold is there in gold ore?
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons).
What makes gold impure?
Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. … The impurities form chloride compounds that separate into a layer on the surface of the molten gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity.
Does melting gold purify it?
Does melting the gold purify it? Yes. In fact, melting is the oldest method to purify gold with fire. However, since the melting temperature of gold is 1064 degrees centigrade, melting at this point leads to high risks of severe burns.
Who purifies gold?
Miller Process This process is known to purify gold to 99.95%. This method got its name from Francis Bowyer Miller, its inventor. In the Miller process, unrefined gold is first melted. Then, chlorine gas is passed through it.
What does fire do to gold?
The dore has to go through a trial by fire at a refinery. In an exciting process called refining, it is re-liquified in a furnace and then heaped with generous amounts of soda ash and borax. This effectively separates the gold from impurities and other metal traces.

In addition, these pumps are reliable, durable, and energy-efficient, making them ideal for demanding wastewater treatment requirements.
Agriculture and Irrigation
Long shaft sump pumps are commonly used in agriculture and irrigation to extract water from deep wells and aquifers. These pumps are designed with long shafts that allow them to reach water sources several meters below ground level.
One of the primary advantages of using long-shaft sump pumps in agriculture and irrigation is their ability to deliver water to crops in areas where water sources are limited or inaccessible. These pumps are particularly useful in dry regions with scarce and reliable rainfall.
Long shaft sump pumps are also effective in preventing soil erosion by delivering water directly to the roots of crops. This helps to ensure that crops receive sufficient moisture to thrive and reduces the risk of soil runoff and erosion.
These pumps are relatively easy to install and maintain, making them popular among farmers and irrigation professionals. They are also cost-effective, particularly in areas with relatively low electricity or fuel costs.
However, using long-shaft sump pumps in agriculture and irrigation can also have drawbacks. For example, excessive pumping can lead to the depletion of groundwater resources, which can have negative environmental and social impacts. In addition, improper installation or maintenance of long-shaft sump pumps can lead to mechanical failure or reduced efficiency.
Using long-shaft sump pumps responsibly and sustainably is essential, considering the needs of both farmers and the environment. This can be achieved by properly maintaining and managing irrigation systems and adopting practices promoting soil health and conservation.
Long Shaft Pumps as a Key Solution for Industrial Pumping Needs
The long shaft sump pump efficiently removes water from basements, crawl spaces, and other low-lying areas. Its design allows it to reach greater depths than traditional sump pumps, making it ideal for larger spaces or areas with high water tables. The long shaft also reduces the need for frequent maintenance and repairs since it is less susceptible to damage from debris or sediment. Additionally, its energy-efficient operation can save homeowners money on electricity bills in the long run. Overall, the long shaft sump pump is a reliable and cost-effective solution for keeping homes dry and protected from water damage.

The Carboniferous Limestone (Cil yr Ychen/Dowlais Limestone, the Penderyn Oolite and the Penwyllt Limestone) has been exploited since the Middle Ages. It was burnt for use in agriculture and the metal industry and also used for construction.
The concentration of limekilns in the Geopark dates from the 18th and 19th centuries when lime was in great demand first for agriculture, for construction and later for the rising iron and copper industries. Coal provided the main fuel for burning lime during this time. In earlier periods charcoal was used in lime burning, and the use of wood would have had an impact on the remaining woodland in the area.
What is a flux?
A flux is used in both the iron and copper-making processes to get rid of impurities such as silica (SiO2) First the limestone (mostly CaCO3) is burnt (‘calcined’) in a kiln to form quicklime (CaO). This is added to the iron ore and reacts with the silica to form calcium silicate (‘slag’) which is then separated off from the molten iron or copper.
CaO (quicklime) + SiO2 (silica) -> CaSiO3 (calcium silicate /’slag’)
The requirement for limestone on a large scale as a flux in the smelting industries of South Wales was initiated by the development of copper smelting in the lower Swansea valley. Copper smelting began in the Swansea and Neath districts in 1717 and the Swansea area was established as a copper smelting centre by 1720. By 1778 copper smelting at Swansea was regarded as Britain’s major industry and Swansea remained the world centre for copper production until 1920. Quarries in the Geopark area, particularly at the Cribarth, supplied limestone as a flux for the copper smelting industry.
In 1759 John Wilkinson together with his partners began to smelt iron at Merthyr Tydfil on the southern edge of the Geopark. The initial use of charcoal for this purpose was replaced in the second year of production by coke under the direction of John Guest, the company manager. In 1763 Anthony Bacon developed the great Cyfarthfa Ironworks. Bacon was succeeded by Richard Crawshay and under his leadership the improved puddling process for producing wrought iron – the Welsh method – revolutionised the industry. The industrial belt which developed along the northern rim of the South Wales coalfield required limestone as a flux in the smelting process. This demand was met by quarries within the Geopark.


An Introduction To Coal Mining In Australia
Australia is a country that is rich in resources and mining, both under ground and in open pit mines has been a major part of the the national economy and not only in GDP but also in employment and the creation of communities and and industry solely because of the mining sector.
History Of Coal Mining In Australia
The first record of coal in Australia dates back to 1797, however at that time the coal seemed so inaccessible – so there was no attempt to extract any of it.
In 1908, however, they started extracting from this site, removing almost 2,000,000 tonnes of coal.
Queensland was know to have coal deposits shortly after settlement in the Moreton Bay area, and the area has been worked almost continuously since that time.
Coal is now mine all around Australia, in fact there are mines in every single state and territory, and while 75% of all coal mined in Australia is exported, the final 25% accounts for almost 85% the energy production throughout the country.
Australia is the world largest exporter of coal, each year sending over 260 million tonnes overseas. The major export markets for Australian coal is Japan (40%), Korea (16%) and Taiwan, China & India (9%), and the company that exports the most coal is BHP Billiton.
Coal Mining Jobs
As coal is mined all around the country, there are plenty of mining jobs on offer at any one time. Obviously those applying with tertiary qualifications and and trade (relevant) experience are more likely to be successful with their applications.
It is not uncommon for some unskilled mining positions to receive upwards of 300 applicants, so it is easy to see why a lot of job hunters become disillusioned. However, the more training and experience that you can gain – the greater your chances success when applying for entry level mining jobs – be that in the mines or surrounding industries.
Information About Australia
So that is a basic introduction to coal mining in Australia but let’s take a closer look at the country behind this mass of energy fueling resource.
Stats About Australia:
- Claimed by Britain in 1770
- Made Up Of 6 States & 2 Territories
- Population Of Almost 22 million

Aside from coal mining, Australia also is a major miner of iron ore, diamonds, gold, uranium and a lot of other precious and semi-precious minerals. Although mining is one of the major exports of Australia, the country also has major exports in primary industry, wool and sugar.


A slurry pump typically refers to a rubber-lined centrifugal pump. Generations of use in mining slurry pumping has earned the rubber-lined centrifugal pump the reputation as the first choice for this application. But recently, emerging technology and increased awareness of positive displacement (PD) slurry pumps have broadened the landscape of pumping options for slurry applications.
The traditional centrifugal slurry pump consists of a pumphead or volute, usually split vertically. Within the pumphead are two rubber liners that mate together once the volute is assembled.

Action is generated by the rotating impeller—hardened metal or elastomer-coated metal.
Several PD pump technologies that are appropriate for slurry pumping have emerged. The current most popular one is mechanically actuated diaphragm pumps, followed by others such as peristaltic hose pumps, air-operated diaphragm pumps, rotary lobe pumps and progressing cavity pumps. PD pumps have advantages over?centrifugal pumps?in certain situations, especially in low-flow, high-pressure applications. They also have advantages in applications with low net positive suction head available (NPSHa) and when pumping viscous or high-solids products. Water use and power consumption are the primary contributors to upkeep costs.
Image 2. Peristaltic hose pump principle of operation
Peristaltic hose pumps can circulate slurry with up to 80 percent solid content, with specific gravity of 1.6 to 1.8. Traditional centrifugal slurry pumps typically operate around 1.3 specific gravity, but can pump 50 percent solids in some services before suffering wear or hydraulic issues. Given a 75 tons per hour (TPH) ore processing rate, using the above slurry concentrations, a peristaltic hose pump will need to pump 210 gallons per minute (gpm), while the centrifugal pump moves 457 gpm—a difference of 247 gpm.
This calculation shows that to process 75 TPH of ore, a centrifugal pump will require 130 million additional gallons of water over the course of a year. Depending on the mine location, the cost of industrial water can range from 0.4 cents per gallon in the U.S. to 1.6 cents per gallon in Australia, and several times more in arid, remote locations.
Consider water reuse in this analysis. Reclaiming used water carries inherent cost in electricity, equipment, maintenance, etc. However the cost is much lower than purchasing new water. Most U.S. mines are at about 90 percent reuse, with some mines approaching 100 percent reuse. This means (not accounting for the cost to clean used water) that a mine with 98 percent reuse paying $0.04 per gallon for new water would save about $104,000 per year in water usage by operating a peristaltic hose pump.
Image 3. Annual water cost savings by price per gallon
On the same 75 TPH process operating at 90 pounds per square inch (psi) system pressure, a properly sized peristaltic hose pump requires 28.5 brake horsepower (bhp) for operation. By comparison, a centrifugal slurry pump requires 39.8 bhp (assuming 60 percent hydraulic efficiency). Power consumption varies between the two technologies with the centrifugal pump requiring up to 30 percent more power to operate. Electricity rates vary. Power in the U.S. costs around $0.10 per kilowatt hour (kWh).
Images 3 and 4 are based on assumptions that a peristaltic hose pump (or other PD pump) can operate at 80 percent solids concentration and that the centrifugal slurry pump operates at 50 percent.
Image 4. Annual electricity cost savings by price per kWh
Consequently, as slurry solids content increases, the total water usage decreases, thus decreasing the amount of makeup water required. Another assumption is that the centrifugal slurry pump will operate at 60 percent hydraulic efficiency. Independent of all other factors, the cost of water and electricity usage for centrifugal slurry pumps can be compared with that of PD pumps taking into account the pumped slurry solids concentration per pump type, water cost and reuse rate, and electricity cost. In general, positive displacement pumps such as hose pumps will use less water and power in applications of 75 TPH or less, and moderate discharge pressure.

What Cheer, Iowa officially became a town in 1865. By the late 1880’s, What Cheer had become a “boom town” due to the extensive deposits of coal in the area. Two railroads serviced the town carrying both freight and passengers. There were 13 mines in operation as well as more than 50 manufacturing and processing plants. Among the many products made were mining tools, wood stoves, buttons, overalls, shoes, and soft drinks.


Smart supply chain for the minerals and metals sector
The initiative will enable the digitization of the mineral and metal value chain in order to secure supply chains and improve their performance. Among other benefits, the project will make it possible to measure the socioenvironmental impact of these value chains thereby maximizing the Canadian industry’s competitive advantage, while making better and more planet-friendly use of resources. The development of highly advanced AI algorithms will provide an essential tool for industry stakeholders to meet commercial and environmental requirements.
Louis Roy, president and founder of OPTEL: “In addition to providing commercial partners with information on the provenance of materials in circulation, the data collected and analyzed will make it possible to put concrete measures in place to improve the sector’s environmental performance in relation to the circular economy, from extraction to utilization, as well as the recuperation of materials.”
Scale AI investment
“An intelligent supply chain will allow Canada and its trading partners to optimize their commercial exchanges.”


With South Africa’s growing demand for water – and the impact of climate change on rainfall variability and water supply security – the need for a systematic approach to water stewardship in mining has never been greater.
Water management has long been a focus in the mining sector, according to Lindsay Shand, associate partner and principal environmental geologist at SRK Consulting. In 2014, the International Council on Mining and Metals’ water stewardship framework outlined a standardised approach for mining companies, recognising that water connects an operation to the surrounding landscape and communities.
“In our past work with mining clients, SRK often addressed a particular challenge, rather than taking the broader view,” said Shand. “However, there is a growing recognition that a high-level, concerted approach to water stewardship is environmentally responsible and contributes to building resilience in the mining operation.”
This resilience lies in the ability to identify and manage water risks, including water supply uncertainty, water quality compliance issues, and downstream discharge impacts. A water stewardship approach allows for pro-active planning and action to avoid incidents threatening operations and presenting a liability to downstream water users.
Tools for progress
While the focus for mining operations is generally on a specific challenge, corporations are starting to see the value of the bigger picture on water issues, said Fiona Sutton, principal consultant at SRK Consulting.
“Often, the scope and demands of water stewardship seem a daunting prospect at operational level,” said Sutton. “This is one of the reasons why best practice tools are so useful, such as the International Water Stewardship Standard from the Alliance for Water Stewardship (AWS).”
“Practical steps and guidance in the AWS Standard help water users to improve their practices for better on-site water performance, while also contributing to sustainability goals,” she said.
A water stewardship approach allows for pro-active planning and action to avoid incidents threatening operational continuity
Water stewardship considers impacts not only on the mine site but in the wider catchment in which it operates, according to Dr Simon Lorentz, principal hydrologist at SRK Consulting.
“Risks specific to the company can be direct, which disrupt mining operations, such as the non-availability of water supply,” said Lorentz. “They can also be indirect, where supply chains are disrupted due to water supply or water quality issues.”
He noted that catchment-specific risks are influenced by local water management and governance effectiveness in dealing with factors such as increasing demand and unpredictability driven by climate variability. They are also affected by local infrastructure adequacy, pollution disposed into water bodies, and the quality of available water.
The centrality of water in the UN’s SDGs is another reason why mining companies are starting to embrace water stewardship, said Sutton. Many corporates align their strategies with the SDGs, many relevant to water.
“An added advantage of the AWS Standard is that it allows mines to be accredited once they have met the detailed range of requirements,” she said. “This is valuable in terms of companies’ reputations – whether in the eyes of investors, financial institutions, regulators or the general public.”
The AWS’s position as a member of ISEAL assures stakeholders that its water stewardship framework has been reviewed by an independent and competent body. The framework and the accreditation provide a credible benchmark as a true indication of commitment.
“SRK’s decades of experience in the mining sector, combined with its depth of expertise in water-related disciplines, positions us well to guide mining companies in their water stewardship journey,” said Shand.

A ball mill is a machine for grinding, mixing, or blending different elements. A ball mill is seen as one of the most effective and cost-effective technologies in milling.
This sustainable technology is fast becoming extremely popular. Ball mills are used in paints, pyrotechnics, mineral dressing processes, selective laser sintering, and ceramics.
The since behind the ball mill is simple. It uses impact force to reduce the size of materials. One of the advantages of a ball mill is its simple design and operation. It is one of the oldest designs in milling.
Ball Mill manufacturer uses Balls in a hollow cylindrical chamber to continuously pound the material. The balls, in continuous motion, keep moving over the material inside, milling it. Ball mill manufacturers received a technological boost during the industrial revolution when steam energy was used to make the mill movement smooth and efficient.
Construction of the ball mill
The ball milling consists of a cylindrical vessel mounted on its two ends. The vessel rotates around its central axis. The vessel contains a grinding medium, which are the balls that give this mill its name.
The balls can be made of different materials, such as steel, pebbles, rubber, or ceramic. Industrial Ball Mill manufacturer are made to operate continuously, ensuring that the balls keep going inside the vessel. It is an efficient system where the relentless action of the balls produces a pleasing effect.
The vessel’s shell has a girth gear and a pinion shaft, which move the vessel. The vessel is filled partially with the material and the grinding media (the balls).
As the mill rotates, the heavy grinding media keeps moving with the motion. Its weight and kinetic energy break down the material. High-end ball mills are capable of grinding to a very fine product.
Factors to keep in mind when making a ball mill
There are some essential factors that ball mill manufacturers have to keep in mind:
The lining of the cylindrical vessel is an important criterion. The unceasing action of the balls, combined with the materials that go from bulky to coarse to fine texture, can take a toll on the lining.
This is constant abrasion, which can cause serious wear and tear. Hence, we have to minimize the effect of sharp edges and impact force. Popular choices are abrasion-resistant materials like rubber or manganese steel.
Rubber is one of the most effective materials in this regard. Rubber-lined walls are among the most wear-resistant mill lining.
2. Ball media
The ball mill processes various materials, from silicates and glass ceramics to ore dressing ferrous and non-ferrous material. The mill can grind materials wet or dry. There are many kinds of ball media used in these mills.
We must select these carefully. There are three important factors that one must keep in mind when selecting the ball media:
The ball media must be heavier than the material being ground. Otherwise, it would simply stay or float on top of the material. A lighter material will not have enough force to make any meaningful impact on the material.
The ball media must be hard enough to withstand the constant grinding action. However, we also have to consider the wear and tear on the mill lining.
The ball media size must be substantially bigger than the largest of the materials to be grounded. But keep in mind that you cannot have very large-sized media. The smaller the ball size, the smaller the grounded material will be.
The composition or the material of the ball media is itself important. If the material of the media is to be part of the finished product, we have to see that it achieves the objective.
But if that is not the case, the media’s reaction to the grounded material must be evaluated carefully. The ball’s impact and reactivity can occur in many forms.
The color of the balls can bleed into the material, or dust or particles from the ball can contaminate the final product. Ferrous metals can react with certain media. Flammable materials must be handled carefully.

Here we see views from one of the open cut mines, looking back towards the town of Peak Hill.
Gold was discovered at Peak Hill in 1889.
Peak Hill was described as a high hill of felspathic rock containing large masses of iron, ferruginous quartz and quartzite.
The historic mine operated between 1893 and 1917 producing about 60,000 ounces from 500,000 tonnes of rock. Alkane excavated for gold on the site between 1996 and 2002 retrieving 145,000 ounces from 4.9 million tonnes.
While much of the historic operations were consumed by the recent mining activity, Alkane has managed to preserve some of the old workings.
The mine was closed 2002 and is now open for public viewing.
The Open Cut Experience includes both the historic works and the more recent mines,several walking paths have been constructed.
Self guided tours are FREE.
Mine tours can be booked for groups of 20 or more people
