Copper Lead Separation with Activated Carbon

The basic components of the flotation circuit involve the combination of a differential circuit for copper/zinc separation and a bulk/selective circuit for copper/lead separation The use of a bulk/selective circuit for removing galena from chalcopyrite is an obvious choice upon examining the relative quantities of the two minerals in the bulk concentrate


A Review on Novel Techniques for Chalcopyrite Ore Processing

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


Galvanic Interaction between Chalcopyrite and Pyrite with
