Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively electroplating pure copper from this electrolyte without the anode impurities. It produces copper essentially free of impurities, and separates valuable impurities such as gold and silver from copper for recover as by products. They are composed of: Electrolysis Cells Each cell is equipped with: • Heater • level control • Cathodes • Electrical contacts in stainless steel
Gold, Silver and Copper Electrolysis
With this plant it is possible to obtain gold with a purity of 999,9/1000 starting from 900/1000 with a maximum silver content of 5 %. Each 35 lt tank produces from 12 to 15 Kg each in 24 hours. the electrolyte solution should contain 80gr/lt of gold chloride. the plant consists of a single cell divided into two tanks, made out of self-extiguishing ppl, and resting on a safety tray. the refining cell is fitted with a suction manifold around its borders.
The plant consists of modular units that allow the production of the very purest silver. Each tank can refine from 15 to 35 kg per day. Fast collection of the pure silver crystals discharged from the tanks. Fume extraction hood which allows easy installation of the anodes. Electrolyte recycling pump which prevents unwanted deposits of silver on the anodes. Current rectifier with electronic voltage stabiliser.
