SIMULTANEOUS ELECTRODISSOLUTION AND ELECTRO- WINNING OF METALS FROM SULPHIDE MINERALS ABSTRACT OF THE DISCLOSURE The specification discloses a process for simultaneous electrodissolution and electrowinning of metals from simple sulphide minerals comprising establish- ing a cell having: anode compartments containing a suspension of particulate sulphide mineral and providing an oxidizing enviroment; cathode compartments in which liberated metal values are recovered; ion permeable membranes separating anode and cathode compartments; and an electrolyte containing anions of soluble salts of the liberatable metal both in the anode and cathode compartments; introducing direct electric current into the cell and recovering metal values from the cathode. The process is substantially non-polluting and therefore advantageous over the known devices.
