A study has been made of the electrochemical behaviour of carrollite and chalcopyrite in the presence of xanthate and cyanide in aqueous solution. The investigations involved measurements of rest potentials and cyclic voltammetry of the sulphide minerals understudy. The results showed that the...

Current densities from 40O Am to 1000 Am were used to investigate the electrowinning of cobalt from sulfate solutiaiie. The cell used was a cylindrical beaker of 1000 ml capacity. Two lead anodes and one stainless steel cathode were used as - electrodes. The cathode was prepared electrolytically...
