Copper extraction Wikipedia

The purity of this product is 98%, it is known as blister because of the broken surface created by the escape of sulfur dioxide gas as blister copper pigs or ingots are cooled. By-products generated in the process are sulfur dioxide and slag. The sulfur dioxide is captured for use in earlier leaching processes. Fire refining

Blister Copper an overview ScienceDirect Topics

The produced concentrates are smelted to remove volatile and other impurities and by further purification of the copper melt from the smelter, a primary form of the metal, known as blister copper is derived. Higher purity copper is then produced by electro-refining (Cooper, 2005). The main waste materials within this process are the tailings

copper extraction and purification

The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.
