    The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

    Froth floatation method is commonly used for the concentration of the low-grade sulphide ore. The principal is based on the fact that gangue and ore particles have a different degree of wettability with water and pine oil. The ore particles are wetted by oil whereas gangue particles are wetted by water.

    Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

    Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.

  • Copper Mining and Production Processes Explained

    Copper Mining and Processing: Processing of Copper Ores. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit.

  • of processing minerals and ores

    Mineral processing comprises many unit operations, such as gravity concentration, magnetic concentration and flotation, which are all aimed at extracting valuable material from ores. Usually, the process operation conditions are defined to control the balance between a high recovery of the desired metal and a high grade value of the metal in ...
