Copper production & environmental impact

Extraction of copper from minerals • Involves a series of chemical, physical and electrochemical processes • Depending on whether an ore is sulfide or oxide, the process follows one of two routes Beneficiation • Beneficiation is the concentration of ore through separation into desirable mineralthe part of the ore that is useable; and gangue (pronounced ‘gang’) – the part of the4 Beneficiation of Copper Ore The next step in processing is called beneficiation This is the first step in concentrating the copper into a more useable form 5 Smelting and Extraction The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution 6From Ore to Finished Product Copper
