Copper extraction - Wikipedia
The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as chalcopyrite , the ore is crushed and ground to liberate the valuable minerals from the waste & 39;gangue& 39; minerals. It is then concentrated using mineral flotation.Flotation separation of chalcopyrite from talc using a new depressant ...Chalcopyrite CuFeS 2 is the major sulphide mineral for Cu extraction, containing about 70 % of total copper reserves globally within all types of copper bearing ore in mineral processing , , .The chalcopyrite has to be enriched by flotation, otherwise smelting would not be applicable.Processing of chalcopyrite ore by heap leaching and flotationThis study explored the processing of chalcopyrite ore through heap leaching followed by flotation. Crushed and agglomerated chalcopyrite ore was subjected to bacterially-assisted leaching at ...
