Electrolytic Refining Meaning, Electrorefining of Copper
Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode.

Electrorefining an overview ScienceDirect Topics
Electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H 2 SO 4 and then electrochemically depositing pure copper from the electrolyte onto stainless steel or copper cathodes. The process is continuous.

Electrorefining an overview ScienceDirect Topics
In an electrorefining process, used to recover lead from the grids and poles, the lead scrap outside the electrolysis cells is solubilized by a ferric fluoborate solution with fluoboric acid (called CX-EW process, Olper 1995a ). The extracted lead is deposited in the cathode compartment of a diaphragm cell. The following reactions take place:
