Copper Electrolysis

Aug 21, 2014· Why extract copper through electrolysis? Copper is not found in a usable form, it is naturally found in very small amounts inside ores. The ore that wield the copper is called Chalcopyrite (Copper iron sulfide, CuFeS₂). The process that needs to take place before the copper goes through electrolysis is its ore needs to be mined out of the ground.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Extraction Copper information provided by Copper

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
