Abstract
Silver recovery systems operating at the higher current densities require thorough solution agitation at the cathode surface in order to deposit metallic silver continuously. In the apparatus described, agitation is provided by an external pump. With the solution nozzles located tangential to a cylindrical cathode, high surface velocity is attained and mass flow held to reasonable values. Thus, the problem of excessive mechanical energy input is avoided, while the scrubbing velocity provided permits current densities as high as 10 amp/sq ft.
