Electrolytic production of copper from chalcopyrite
Such slurry electrolysis is analogous to the alkaline process for iron oxide where solubility is limited [5], although in the latter iron is directly electrowon, while for the former, the outlet solution would then undergo electrowinning in a different cell. The main challenge for chalcopyrite processing is the formation of a metal-deficient ...

Electrolytic Powder Processing
Electrolytic powder processing is a technology of metal or alloy powders obtained by electrolysis from metal salts (electrolytes). The principle of the metal powder prepared by electrolysis is that an electrochemical reaction is carried out by applying direct current and the metal cations are reduced by accepting electrons, precipitating on the cathode.

Copper processing
For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) …
