COPPER PRODUCTION Extracting copper from its ores The ...

Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2 Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.

Copper Ore Hydrometallurgy and Pressure LeachingCopper

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electrowinning (EW). It can produce either copper cathode or copper sulphate crystal.
