copper ore concentration process

copper ore concentration process

Mined from open pits,copper oremust be crushed as part of theprocessthat occurs between extraction and production. Using today’s compact mining equipment,copper oreis extracted from the mine. After theoreis crushed, it’s roasted, which helps to convert sulfides to oxides.

    Copper Mining and Processing Processing Copper Ores

    The mostcommon types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. 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 …

    Copper processing Roasting, smelting, and converting

    In the hydrometallurgical processes, the ore or concentrate is brought into close contact with a leach solution (frequently sulfuric acid) that dissolves the copper and leaves a residue of gangue (and frequently precious metals). Various systems, some quite complex, are used to bringcopper minerals into contact with the leach solution,wash and filter the residue, andfinally purify the solution to remove dissolved iron and other impurities.
