Abstract

An apparatus for removing metals from solution by electrowinning is described. It comprises a plurality of chambers in an endless annular array. Each chamber contains a plurality of submerged cells including a porous anode and cathode. A suction pump which draws solution from the chamber through the anode and then the cathode and discharges the solution back into the chamber. There are a valve controlled inlet to and a discharge from each chamber together with a valve controlled connector connecting the chambers to one another. The first chamber is filled with loaded solution and after treatment in the first chamber the solution is passed to the next chamber and so on around the annulus. By changing the valve settings the next chamber becomes the 'first' chamber and this continued around the annulus. The metal adhering to the cathode is removed by flushing liquid or preferably by ultrasonic waves.
