ABSTRACT:
In the recovery of an electrically conductive metal from a liquid containing the metal in solution, a cathode member for deposition of the metal by electrolysis, comprises a carrier sheet with a cathode element of the metal to be recovered, on one side of the sheet; the carrier sheet is of a material from which the metal is readily refinable when smelted with the carrier sheet; the cathode member has particular application for removal of the silver content of fixer solution in photography; suitably the sheet is flexible and has a memory of a planar state, such that on being rolled into a cylindrical tubular configuration, it returns to the planar state unless restrained.
