Abstract
An electrolytic stripping cell is provided which is particularly adapted for use in processing shredded, silver brazed, stainless steel honeycomb scrap. The cell comprises a mesh anode basket which rotates within a cathode cylinder to provide partial stirring of the cell electrolyte. The anode basket includes a central hollow shaft having holes therein through which the electrolyte continually circulates. The basket includes wiper blades for dislodging silver dentrites which grow between the anode and cathode and which, as they fall, are collected in a mesh basket located at the bottom of the cell housing.

An electrolytic stripping cell for recovering silver and other metals from bulky, low density scrap containing such metals, said cell comprising:
- a rotatable perforated basket for receiving charge of said scrap and constituting one electrode of said cell;
- a metallic cylinder surrounding said basket and spaced therefrom, said cylinder constituting the other electrode;
- a housing in which said basket and said cylinder are contained;
- means for supplying an electrolyte to said cell;
- and means for rotating said basket to provide agitation of the electrolyte within the cell, said means for supplying an electrolyte to said cell including a hollow shaft disposed centrally of the cell and having a plurality of openings along the length thereof through which said electrolyte passes.
