Date Oct. 14, 1993An electrochemical system for the recovery of metals from metal ores in which reactions are carried out in separate anode and cathode tanks with the liquid product from the anode tank being separated and purified before being returned to the cathode tank for metal deposition. The separation includes thickening such as liquid solid separation with the liquid proceeding to the cathode tank. A reaction stage may be included before the thickening stage. Purification may include removal of impurities, adjustment of chemical and physical conditions and the addition of cathode reaction enhancers.
