Abstract

Metal is electrodeposited on conductive granules in apparatus comprising a helical channel with a cathode at its radially outer side and an anode at its radially inner side. A suspension of the granules in an electrolysis solution is fed tangentially into an end of the channel so that the granules are urged by centrifugal force against the cathode and form a mass moving along the channel to its outlet. The emerging granules are separated from the used solution in a cyclone and the solution is recirculated along the axis of the helix.
