1/8/2019· Refractory gold ores are those which yield less than 80% metal extraction during direct cyanidation (Ciminelli, 2005). Mostly, refractoriness is ascribed to gold particles being locked in a non-porous sulphide matrix in minerals such as pyrite, chalcopyrite, pyrrhotite, arsenopyrite and stibnite ( …

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. However, some ...

17.5 FLOTATION OF GOLD-CONTAINING MERCURY/ANTIMONY ORES In general, these ores belong to a group of difficult-to-treat ores, where cyanidation usually produces poor extraction. Mercury is partially soluble in cyanide, which increases consumption and reduces extraction. A successful flotation method [5] has

containing aurostibite. For the treatment of high grade silver-gold ores (> 100 g/t Ag) efficient cyanidation of high grade silver-gold ores (> 100 g/t Ag) was possible with only 500 ppm NaCN. Low consumption of cyanide and low effluent treatment costs were obtained. Keywords: Gold, silver, extraction, sulphide, cyanide.

REFRACTORY GOLD. By definition, refractory gold ores contain gold that is resistant to extraction by conventional chemical processing and as a result responds poorly to traditional gold cyanidation techniques such as Carbon-in-Leach (CIL), yielding less than 80% of the contained gold.

The Refractory Gold Containing Sulfide Ores are characterized by complex structure, by extremely thin impregnation of gold in sulfide ores (so called fine-particle gold with particle size from 1 to 5 micrometer), and by presence of components, which decrease the extraction of gold under cyanidation.

Gold extraction and cyanide consumption were 95% and 7.4 kg/t. The Kupol mill was the first commercial application of the CELP. The plant processed a high grade free milling gold/silver ore containing 28.2 g/t Au, 324.8 g/t Ag and approximately 0.5% pyrite during 2008 operation.

In fact, today, cyanidation is the only choice for the recovery of gold from low-grade and finely disseminated gold ores in both technological and economical respects. Two of the main advantages of cyanidation are the selectivity of free cyanide for gold dissolution and the extremely high stability of the cyanide complex [ 6 ].
