Copper extraction can be divided into three steps: (i) roasting (which can be optional for some copper-making routes); (ii) matte smelting (reverberatory, electric, or flash smelting furnaces); (iii) converting (conversion of matte to blister copper ). The purpose of matte smelting is to separate the metal sulfides (Cu 2 S–FeS) from the gangue.

Which process are used for extraction of copper? The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (CuFeS2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest
