In refining copper, an aqueous solution of copper(II) sulphate is electrolyzed, using impure copper as the anode and pure copper as the cathode. At the anode, metal impurities higher than copper in the electrochemical series such as zinc, iron and lead are oxidized first, then copper loses its electrons to form copper(II) ions.
Electrolysis or electrolytic refining is a technique used for extraction as well as purification of metals obtained by any refining method. In the electro- refining process, a block of impure metal is made the anode and a thin sheet of metal is made the cathode.
Products/Services for Copper Refining Equipment Refining and Recovery Equipment - (16 companies) Refining is the process of purification of a substance or material.
The object of refining copper in the reverberatory furnace is to obtain a metal which will have the highest attainable degree of malleability, ductility and electric conductivity, and present at the same time a level surface when it solidifies in the mold after casting.
