Copper Purification Process - Electrolytic Copper

Electrolytic Copper Refining Tank: the anodes of impure copper are refined by electrolytic means to the pure cathode copper in the refining tank. It is filled with a solution of sulfuric acid and copper(II) sulfate, in which the anodes and cathodes are interleaved and immersed — between anodes are suspended starting sheets which are thin sheets of electrolytic copper.

recovery copper cells - transports-arcc.ch

Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost.
