The required amperage is determined by the plant metallurgists and entered into Citect as a control set point. The output of the rectifiers is maintained at the set point by a control loop. The optimum amperage is somewhere in the range of 30 to 50 amps per cathode. Electrowinning Cell . RESOURCE BOOK 8888 Solution ...Electrolytic Refining of GoldThe method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in .Electrorefining of CopperAqueous electrorefining — The conditions used for the refining of five metals are summarized in Table 6.3.1. The electrolyte and other conditions must be selected so that both the anodic dissolution and the deposition of the metal occur with high efficiency while none of the impurity metals can transfer from the anode to the cathode. Certainly there must be no passivation of the anode (cf ...Electrorefining of CopperAqueous electrorefining — The conditions used for the refining of five metals are summarized in Table 6.3.1.
