Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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. Concentration of Ore:

Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
