Copper Purification Process Electrolytic Copper Refining

Electrolytic refining (electrorefining) is a process used to make impure copper pure Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores By electrolysis, it can be refined and made very pure—up to 99999% The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxideAn electrolytic method for the recovery of pure copper from sulphate solutions is far preferable and will produce cheap copper In all cases a low current density is required Hardlead anodes or composite anodes of hard lead and coke of uniform thickness will be usedHow to Recover Copper from Solution
