  • A Review on Novel Techniques for Chalcopyrite Ore

    01-01-2012· 2.1. 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.

    Copper extraction Wikipedia

    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 (' gangue ') minerals. It is then concentrated using mineral flotation. The concentrate is typically then sold to distant smelters, although some large mines have smelters located nearby.
