ABSTRACT:
This disclosure relates primarily to the recovery of hydrogen-reduced metals from aqueous solutions of salts thereof, such as, for example, copper from copper sulphate solution, by hydrogen reduction at a catalytic barrier made pervious to the solution, in an apparatus provided with means to supply hydrogen along a face of said barrier at which the aqueous solution is applied to effect deposition thereupon and flowing the solution transversely through the barrier to continue deposition upon the other face of the barrier.
