摘要： A process for simultaneous electrodissolution and electrowinning of metals from simple sulphide minerals comprises establishing a cell having(i) an anode compartment or compartments containing a suspension of particulate sulphide mineral, the metal content of which is being selectively liberated by an oxidizing environment attributable to the anode;(ii) a cathode compartment or compartments in which the liberated metal values are electrolytically recovered;(iii) one or more ion permeable membranes, impermeable to the particulate solids in the suspension, separating the anode and cathode compartments;(iv) An electrolyte containing anions of soluble salt(s) of the said liberated metal or metals in both anode and cathode compartments;introducing direct electric current into the cell, and recovering metal values from the cathode.
