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.
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.
