    摘要: An efficient electrolytic recovery system, having several safety mechanisms, for recovering precious metals from a liquid medium is described. The system includes at least one electrolysis cell unit (118),(119) having a plurality of reticulate metal foam cathodes. The system of the invention will efficiently recover such precious metals as Au, Ag and Pt. The system may also include a pH adjust means (126) and a means (109) for oxidizing cyanide in the liquid medium.

    摘要: The present invention resides in the discovery that a strip (12) of reticulated foam which is semi-conductive can be continuously electroplated, utilizing a cathode roll (26) which is positioned, in a first electroplating zone, outside of the electroplating bath. An anode (28) is immersed in the electroplating bath. The strip of reticulated foam is first introduced into the electroplating bath (22) and travels in the direction from the anode to the cathode roll prior to contacting the cathode roll. In this way, the strip achieves a partial plate at the anode which provides a current path between the anode and the cathode roll effective for sustaining the plating reaction in said first electroplating zone.
