Electrolytic precious metal recovery system.

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.
