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.

Flow diagram of the copper solvent extraction process. In the extraction unit, the copper is extracted from the pregnant leach solution (PLS) to the organic solution. The raffinate solution (Raff) is recycled. The copper is stripped from the loaded organic solution (LO) to lean electrolyte (LE) in the stripping unit.

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …
