Mount Isa Mines
Mount Isa Mines Limited ("MIM") operates the Mount Isa copper, lead, zinc and silver mines near Mount Isa, Queensland, Australia as part of the Glencore group of companies. For a brief period in 1980, MIM was Australia's largest company. It has pioneered several significant mining industry innovations, including the Isa Process copper refining technology, the Isasmelt smelting technology, and the IsaMill fine grinding technology, and it also commercialized the Jameson Cell column flotation technology. History In 1923 the orebody containing lead, zinc and silver was discovered by the miner John Campbell Miles. Mount Isa Mines Limited was one of three companies founded in 1924 to develop the minerals discovered by Miles, but production did not begin until May 1931.N Kirkman, ''Hilton Mine,'' (Mount Isa Mines Limited: Mount Isa, Queensland, 1990), 2–3. The other two companies were Mount Isa Silver Lead Proprietary and Mount Isa South. These were both acquired by MIM by late 19 ...

Non-renewable Resource Companies Established In 1970
A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions, nuclear decay or atmospheric escape). Conversely, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within time frames meaningful to humans as well. Earth minerals and metal ores Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present i ...

IsaMill
The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills.C R Fountain, ‘Isasmelt and IsaMills—models of successful R&D,’ in: ''Young Leaders’ Conference, Kalgoorlie, Western Australia, 19–21 March 2002'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 2002), 1–12. The IsaMill is primarily known for its ultrafine grinding applications in the mining industry, but is also being used as a more efficient means of coarse grinding.G S Anderson and B D Burford, "IsaMill—the crossover from ultrafine to coarse grinding," in: ''Metallurgical Plant Design and Operating Strategies (MetPlant 2006), 18–19 September 2006, Perth, Western Australia'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 2006 ...

ISASMELT
The ISASMELT process is an energy-efficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines (a subsidiary of MIM Holdings and now part of Glencore) and the Government of Australia’s CSIRO. It has relatively low capital and operating costs for a smelting process. ISASMELT technology has been applied to lead, copper, and nickel smelting. As of 2021, 22 plants were in operation in eleven countries, along with three demonstration plants located at Mt Isa. The installed capacity of copper/nickel operating plants in 2020 was 9.76 million tonnes per year of feed materials and 750 thousand tonnes per year across lead operating plants. Smelters based on the copper ISASMELT process are among the lowest-cost copper smelters in the world.J L Bill, T E Briffa, A S Burrows, C R Fountain, D Retallick, J M I Tuppurainen, J S Edwards, and P Partington, "Isasmelt—Mount Isa copper smelter progress update," in: ''Sulfide Smelting 2002'', Eds R L Stephen ...

Bottom-blown Oxygen Converter
The Bottom-blown Oxygen Converter or BBOC is a smelting furnace developed by the staff at Britannia Refined Metals Limited (“BRM”), a British subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies). The furnace is currently marketed by Glencore Technology. It is a sealed, flat-bottomed furnace mounted on a tilting frame that is used in the recovery of precious metals. A key feature is the use of a shrouded lance to inject oxygen through the bottom of the furnace, directly into the precious metals contained in the furnace, to oxidize base metals or other impurities as part of their removal as slag.J M Floyd, “Submerged bath smelting applied to the non-ferrous metal industry,” in: ''The Paul E. Queneau International Symposium, Extractive Metallurgy of Copper, Nickel and Cobalt, Volume I: Fundamental Aspects'', Eds R G Reddy and R N Weizenbach (The Minerals, Metals and Materials Society: Warrendale, Pennsylvania, 1993), 473–488.

IsaKidd Refining Technology
The IsaKidd Technology is a copper electrorefining and electrowinning technology that was developed independently by Copper Refineries Proprietary Limited (“CRL”), a Townsville, Queensland subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies), and at the Falconbridge Limited (“Falconbridge”) now-dismantled Kidd Creek refinery that was at Timmins, Ontario. It is based around the use of reusable cathode starter sheets for copper electrorefining and the automated stripping of the deposited “cathode copper” from them.J C Jenkins, “Copper tank house technology reviewed and assessed,” in: ''The Aus.I.M.M. North Queensland Branch, Smelting and Refining Operators Symposium, May 1985'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 1985), 195–204.

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...
