Arsenic and Antimony Sulphide Minerals in Cyanidation

The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become ‘foul.’ The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.

Gold Metallurgy & Leaching in Cyanicides

Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming 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 maintained.

Alkaline sulphide treatment of the ore under suitable conditions Gold was shown to leach out up to 85% Sb, which remarkably improved the extraction of silver from b 18% up to 90% Silver Ag in the subsequent cyanidation step. Gold extraction was also enhanced by 20–30%.

Effect of Gold Cyanide Leaching Is Poor? Here Is the

The gold ore contains the cyanide consumption minerals (such as copper, zinc) In addition to the associated minerals that consumes the oxygen, alkali and cyanide, the minerals containing the impurities (such as antimony and selenium) and fine grains that are wrapped in the gangues will also affect the gold leaching.

How Arsenic Affects Cyanidation Leaching of Gold

The Influence of Arsenic in the Cyanidation of Gold Ores is explained by W. B. Blyth has he is of the opinion that the presence of arsenic in an ore does not necessarily cause that ore to be refractory to cyanide treatment. He thinks the idea arose from the fact that arsenic is so often accompanied by antimony, pyrrhotite or graphite, stating that “the two former minerals cause premature
