In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.

Mining at Aitik started on the basis of a 50t reserve, but by 1998 the mine had yielded 300t of ore. As of November 2009, ore reserves were 747t grading at 0.25% of copper, 0.14g per tonne of gold, 1.7g per tonne silver, and 29g per tonne molybdenum. Proven and probable ore reserves amount to 518t and 229t, respectively.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

In the production of copper, sulfidic ores are enriched into concentrates by grinding and flotation, followed by pyrometallurgical processes for the production of pure copper. Oxidic ores are treated with sulfuric acid in a heap leaching process after the grinding stage and are subsequently processed into cathode copper by SX/EW methods.

Within the scope of the study ore grinding performance of the vertical roller mill was investigated with mobile pilot plant. In this context, chalcopyrite ore of a plant having rod and ball milling circuit was ground under different operating modes e.g., air swept and overflow, and process conditions, then samples were collected around the system.

Final comminution of both hard and soft ores is often accomplished by grinding operations using media such as balls or rods of various materials. Grinding is most often performed with an ore/water slurry, which reduces particulate matter (PM) emissions to negligible levels. When dry grinding processes are used, PM emissions can be considerable.

Mount Isa Mines operates two separate mining and processing streams, copper and zinc-lead-silver, near Mount Isa, Queensland, Australia. Its copper operations include two underground copper mines, Enterprise and X41, with ore mining capacity of 6.2 million tonnes per annum (Mtpa), a concentrator with 7Mtpa capacity, a copper smelter, and support services.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, …

Oxide Ores. The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
