Abstract
An apparatus for extraction of metals by electrolysis comprising a means for applying a cathodic current of sufficient magnitude with respect to the cross-sectional dimension of an opening in an insulating coating on a cathode so that a powder-like deposit of anode metal will be made on exposed cathode metal, said deposited metal acting to decrease the current density so that subsequent deposited metal will be in a non-powder like consistency.
