How much metal does the ore contain? « World Ocean Review
Copper ore does not contain pure copper, but either a copper-sulphur-iron compound (chalcopyrite) or a copper-sulphur compound (chalcocite) The metal must first be separated from such minerals by means of multi-step metallurgic process In many cases these processes are so complicated that they account for up to 30 per cent of the metal price
Chalcopyrite is present with many ore-bearing environments via a variety of ore forming process Chalcopyrite is present in volcanogenic massive sulfide ore deposits and sedimentary exhalative deposits, formed by deposition of copper during hydrothermal circulationChalcopyrite is concentrated in this environment via fluid transport
Laboratory Extraction of Copper from Chalcocite by ,
Roughly 90 percent of the copper value occurred primarily as chalcocite (Cu2S), with minor quantities of cuprite (Cu2O), covellite (CuS), chalcopyrite (CuFeS2) and bornite (Cu5FeS4) The remaining 10 percent was present as native copper The major gangue mineral was quartz but there were significant quantities of kaolinite and sericite as well
