mineral processing of copper from cacopyrite Description

Copper Concentrate Enrichment Process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.

A fresh approach to sulfide ores

Jun 26, 2017· One reason for its refractor behaviour is the elemental sulfur layer that forms on the surface of the chalcopyrite particles when they are leached, bringing the copper dissolution process to a halt. The search for a commercially viable, hydrometallurgical technology to extract copper from chalcopyrite and enargite has so far been fruitless.
