Extraction Of Copper Mining, Concentration, Smelting - Byju's

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

Copper Mining and Processing: Processing Copper Ores

The copper compound can now be seen at concentrations of between 60-70%. The second step is solvent extraction, in which two immiscible (un-mixing) liquids are stirred and allowed to separate, causing the cooper to move from one liquid to the other. The pregnant leach solution is mixed vigorously with a solvent.
