Arsenic and Antimony Sulphide Minerals in Cyanidation

Sep 17, 2014  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 Extraction from Different Types of Ore

Jan 10, 2020  Telluride gold ores generally refer to ores containing natural gold and sulfide minerals, which have high economic value. Gold extraction from this type of ore can be different, because whether this ore contains silver or not, it dissolves very slowly in cyanide solutions, so a pre-oxidation stage is usually added before cyanidation. 11.
