cyanidation of gold ores containing antimony

The dissolution of gold by cyanide from a fine ore pulp ...

As a rule, gold ores contain contaminations of metallic elements (cop-per, mercury, lead, zinc, arsenic, antimony, cobalt, nickel) as oxides, sul-fides, arsenides, or antimonides. Most of these contaminations are at least partially soluble in cyanide and are adsorbed on activated carbon along with the gold. Gold will load in preference to copper.

process prior to cyanide leaching. Antimony, bismuth sulfide, and telluride gold ores are often somewhat refractory due to the presence of slow-dissolving gold minerals such as aurostibite (AuSb 2), maldonite (Au 2 Bi), and gold tellurides. Carbonaceous sulfide ores are the typical refractory ores because the gold is fine-grained, and usually,
