Extraction Of Copper Mining, Concentration, Smelting ...

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. Concentration of ...

Recovery of Copper by Solution Mining Methods

A Brief History of Copper Recovery by Solu-tion Mining Methods As early as the 1670, copper-bearing mine waters at the Rio Tinto mine in Spain were known to chemically precipitate copper onto iron (Arbiter and Fletcher, 1994). This process became known as the “cementation process”, which is apparently derived from the Spanish word
