摘要： A silver-containing solution is de-silvered in an electrolytic cell having an anode and a cathode. The diffusion limitation current density of the electrolytic cell is estimated by measuring a current flow there-through and silver is deposited on the cathode at a de-silvering current density which is lower than the diffusion limitation current density.

摘要： Silver is recovered from solutions containing the same, e.g. photographic processing solutions, in an electrolytic cell including an anode, a removable cathode and electrical connectors therefore on the exterior of the cell. The removable cathode is circular in configuration and encircles the anode. On the interior of the cell, electrical contact is made around the upper end of the cathode by means of an annular contact surface providing a large area of contact and minimizing the risk of occurrence of a corrosive connection. The upper end of the cathode is shaped for deformation, preferably in the form of castellations, and is clampingly pressed against the contact surface by a frusto-conical extension of the lid of the cell. The lid fits in threadwise engagement within the opening to the cell through which the cathode can be removed. As the lid is threaded into the cell opening, the frusto-conical extension thereof bears against the deformable cathode end portion and clamps the same against the contact surface. In this arrangement, the contact surface is situated above the level of the electrolyte in the cell so as to be protected against corrosion by the electrolyte.

摘要： A silver recovery device (30) is described for removing silver from a silver-containing solution. The device (30) comprises an ion-exchange resin bed (34) and a pump (62) for directing the solution through the resin bed (34). The pump (62) is positioned downstream of the resin bed (34) and the resin bed (34) is held within a retaining space (36) of variable dimensions. Higher liquid flow rates are thereby achievable, without fluidization of the resin.
