ABSTRACT:
An electrolytic cell for recovering silver from photographic processing solutions comprising an assembly of two or more spaced electrodes which are mounted on support rods and carried within a perforate or imperforate housing. Each electrode comprises a support member such as a frame, one or more sheets of porous flexible material carried by said support member, and a plurality of filaments of electrically conductive material such as carbon distributed across the area of the sheet or sheets, and captured between a sheet and the support member, or between two sheets. The entire electrolytic cell can be formed of combustible materials, and the deposited silver can be recovered after burning the cell.
