Electrolytic refining is a method to purify metals using electricity. A current passes through a metal, removing impurities and enhancing its purity for various industrial applications. Electrolytic refining is mainly used in the process of refining Copper.
Refining of copper Refining processes To obtain the commercial grades it is therefore neces-sary to refine the crude blister by refining processes. The two processes involved are (1) Fire refining process, and (2) Electrolytic process. The second process is normally taken up with the product of the first process. Comparative merits of the too ...
Electrolytic refining of copper: In the electrolytic purification of copper, impure copper is made into an anode and a thin line of pure copper is made into a cathode, a copper salt solution is used as an electrolyte.

Copper Refineries Pty Ltd is our world-class electrolytic copper refinery in Townsville, North Queensland. Using Glencore's proprietary IsaKIDD process, the refinery produces up to 300,000 tonnes a year of 99.995% pure copper cathode—the primary raw material used to produce copper wire, cabling and many other products we use every day.
In electrolytic refining, the plates of crude metal are anodically dissolved in a suitable electrolyte, while "pure" metal is deposited on the adjacent cathodes. The electrorefining process was introduced about a hundred years ago to produce a substitute to fire-refined copper. Today, practically all of the world's copper production (~8,000,000 metric …

REFINEIT-EK is economy modification of REFINEIT for gold refining hobbyists. This system is extremely simple in operation. Place your gold in this system, turn power supply on, wash refined gold.
It needs further refining. This is accomplished electrolytically by using an impure strip of copper as an anode. The electrolyte is an acidified aqueous solution of C u S O 4. For any cell - Galvanic or electrolytic - at the anode, oxidation happens. So the cathode is a strip of pure copper. C u 2 + (a q) gets reduced to pure metallic C u (s).
An attempt is made to summarize and analyze the literature data on the behavior of silver in the process of electrochemical refining of copper.
