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.
