Electrolytic copper refineries have an inherent need to control copper concentrations in the tankhouse.The process of electrorefining copper involves an impure copper anode and an inert cathode. An electric current is applied across the anode and cathode which causes the copper to dissolve from the anode to be then plated onto the cathode as pure ...PROCESSING OF COPPER ANODE-SLIMES FOR EXTRACTION .slag, slimes etc. Electrolytic refining of copper is carried out in Jumbo-cells where a series of cathodes, which are made of pure copper and insoluble lead anodes rest in a steel tanks. Metallic copper is deposited at the cathodes, while the water molecules are decomposed at the anode to produce oxygen. Sulphuric acid is regenerated in the

Electro Copper Refining - Elmhurst University

The end result of of the copper smelter operations is anode copper which is 99% pure (see graphic on the left). An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes.Electrolytic Recovery of Copper and Zinc from Brass.recovery was possible with brasses containing only copper and zinc but that very small amounts of lead would interfere with the dis- solution of the anode. As almost all commercial brasses contain aThe electrolytic recovery of silver from waste silver residuesSilver recovery units of separated copper and zinc plates forming an electrolytic couple are available commercially.
