Baker Botts L.L.P.
Electrolytic cell for removing silver from silver-containing aqueous liquids
 The cell comprises a housing (10), an anode (20) positioned within the housing (10), and a cathode (30) surrounding the anode (20) in the housing (10). A perforated screen (28) is located between the anode (20) and the cathode (30). The construction provides the advantage of a higher and more uniform desilvering speed, due to an improved liquid flow over the cathode surface.
