Electrowinning metals
First Claim
1. A method of electrowinning a metal from an aqueous solution containing ions of the metal which includes the steps of inserting an anode and a cathode into the solution, connecting the anode positively with respect to the cathode, and passing an electrical current through the anode and cathode, characterised in that the anode is a foraminate container containing particulate material comprising electrically conducting, non-polarising compounds of a metal and a non-metallic element, there being provided means to supply the current to the particulate material.
