copper extraction and purification - chemguide

Electrolytic refining. 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…

An Overview of Precious Metal Mining and Refining Techniques

10.5.1.5 Copper extraction using emulsion liquid membranes. Solvent extraction has been routinely used for copper refining since its invention in the 1960s, and it is suggested that well over 10% of refined copper production from ores is obtained by solvent extraction, accounting for millions of tonnes of metal. It is even more popular for ...

Copper Refining: Explained Step-by-Step
