بيت /cyanidation of gold ores containing antimony
In the second part the cyanidation process was applied on roasted and unroasted ore samples. The cyanidation time and grinding time were optimized. The maximum grade of gold ppm and silver ppm was extracted from roasted ore samples at cyanidation time of 35 hours and grinding time of 30 minutes as compared to unroasted ore samples.

Relation to Mining. Of these minerals, only stibnite (Sb2S3) is mined commercially as a source for metallic antimony. Antimony is found in trace amounts in silver, copper and lead ores, and it is usually economically possible, as well as environmentally desirable, to extract the antimony from these ores when they are smelted.

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

This problem occurs when gold ores contain sulfide minerals such as pyrite and arsenopyrite. For gold cyanidation, the cyanide solution must come into direct contact with gold particles. With many sulfide ores, the ore cannot practically be ground down fine enough to expose these particles.
