  • Gold cyanidation Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex.

  • Process for the removal of cyanide and other impurities

    A process for the removal of cyanide and other impurities from an aqueous solution is disclosed. The process comprises adding copper ion and ferrous ion as reagents to the solution at a pH of about 4 to 8 with a ratio of copper to cyanide in the range of 3:1 to 10:1 by weight and with a ratio of iron to copper of at least 0.3:1 by weight.

  • Gold Metallurgy Leaching in Cyanicides

    Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanideconsuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation

  • Effect of Impurities on Cyanide Leach Solution

    That cyanide solutions in works practice do not remain pure in a chemical sense is to be expected, having in view their contact during treatment with the many contaminants found in gold or silver ore amenable to cyanidation. Impurities cause a chemical cyanide loss and at times detrimentally affect the extraction of the valuable metals sought.
