·To date chalcopyrite is the commonest examined copper ore due to its inertness and global abundance indexes Out of between 150 and 180 global copper ores chalcopyrite is the most stabilized copper ore due to its structural configuration [1 2] It is mostly found in association with pyrite FeS 2 bornite Cu 5 FeS 4 sphalerite ZnS chalcocite Cu 2 S
·Mining of Chalcopyrite Chalcopyrite is a common mineral and is found in almost all sulfide deposit and is often disseminated through igneous rock Haver and Wang 1971 For lower grade deposit located near the surface the open pit method is the most practical for the mining of large tonnages of material Large track mounted drill of ore is
·The formation of a passive layer during the hydrometallurgical leaching of copper from chalcopyrite leads to a relatively low copper recovery owing to the halting of the leaching efficiency Thus the copper recovery during chalcopyrite leaching needs to be promoted and the formation of passive layers on the mineral surface must be reduced Organic solvents and
