cyanidation of gold ores containing antimony

Minerals Metallurgical Processing

The leaching parameters were 800 ppm NaCN, DO 16 ppm and pH 10.5 for a duration of 120 hours. The associated cyanide consumption was 4.0 kg/t. Gold leaching was not sensitive to cyanide concentration. Reducing the cyanide concentration to 250 ppm resulted in a gold extraction of 89.5% with a cyanide consumption of 2.6 kg/t. Get price

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. Get price

Gold Ore Contain Antimony

This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively. Get price
