Electro winning (electric extraction) of ATI SANAT Mining and Factories Group (Lotus Machine) and electric refining of this group are the operations of precipitation or electric purification of metals. Both processes are good methods in terms of economy and ease of doing the process for the purification of non-ferrous metals in which high-scale electroplating is used. In electro winning, a current passes through the neutral anode (lead anode) which is in the leach solution containing metal, and as a result, the metal is deposited on the cathode

In electro refining, the anode is made of impure metal, and when the current passes through the acidic electrolyte, the anode is corroded and dissolved in the electrolyte, and the pure metal is deposited on the cathode.
