HYDROMETALLURGICAL PROCESS FOR THE PRODUCTION OF COPPER

We claim 1. A hydrometallurgical process for the production of metallic copper comprising a reduction stage in which materials containing copper-iron sulfide ore concentrates are introduced into an aqueous chloride solution containing cupric chloride to solubilize part of the copper in said materials and reduce a substantial portion of the cupric chloride to cuprous chloride, the total

Copper

Copper is the best non-precious-metal conductor of heat and electricity on the planet, so items that contain copper tend to operate more efficiently. According to the International Copper Association (ICA), using more copper in motors and appliances can reduce carbon dioxide emissions by 1.25 gigatonnes – equivalent to taking half a billion
