Leaching and recovery of silver and gold and solution of sulfurized electrooxidation

摘要

These include: (a) oxidation of the leach solution due to the use of electric current in the anaerobic part of the diaphragm chamber to separate the anaerobic and catodico; (b) fuel supply to ASI electro oxidation printing plant in the leach solution rich in metal materials; (c) after the leaching solution is completed, the mixture is separated from the exhausted ore; (d) the rich solution is fed to the catodico part of the same partial sulfur oxide cell; (E) the metal is reduced and electrolyzed into the catheter, and then disposed of in the traditional way;(f) remove a portion of the solution from the electrolysis operation and compensate for the loss of reagents in the treatment process to regenerate the sulfur stream, which feeds again at the beginning of the treatment process. This improvement is characterized by that the leaching solution can be used to clean the acid solution after washing to reduce the metal content based on this material; the acid content is 0.1 to 10 mol / L, and the material is 1 to 500 g / L of acid solution; in addition, the contact time can be Duration from 0.5 to 48 hours, with or without disturbance
