ABSTRACT:
The device is a small, portable receptacle having a top closure and a bottom closure which are sealingly joined to define an interior cavity which holds a small battery. A cathode plate is in electrical contact with the negative terminal of the battery and extends through the bottom closure for direct contact with electrolyzing solution, and an anode is in electrical contact with the positive terminal of the battery and extends through the top closure for direct contact with electrolyzing solution. The unit is especially designed for use to recover silver from photographic fixing solution.
