Refining metallurgyWikipedia

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.

Electrorefining of Copper

Firerefined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage

Copper Mining and Production Processes Explained

 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 SXEW solvent extraction/electrowinning.
