gold ores: Antimony, bismuth sulfide and telluride gold ores are often somewhat refractory due to the presence of ... (Fleming, 1998). Gold recovery from the carbonaceous sulfidic ore is more difficult because the gold is "robbed" from the cyanide solution by the carbonaceous matter (Wan, 2001). Table 1: Gold Ore Types and Gold Occurrence
Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2S3), the antimony (Sb) forms stable ...
Oct 01, 2000· Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption is usually an oxidation step.
*Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.
