| Abstract: | Gold extraction from a gold concentrate with arsenic and high sulfur content are tested with roasting/cyanidation process as an option.Under conditions simulating commercial operations,roasting oxidation of the gold concentrate yields arsenic removal rate and comprehensive oxidation rate of 95% and 92% respectively,and sulfur,both over 95%.Cyanide leaching rate of gold is above 91% after fine grinding and alkaline washing of the roasted calcine. |
