Abstract

The gold grade of high sulfur containing arsenic cyanide slag produced by a gold smelting enterprise is about 4.4g / t, sulfur grade is about 17% -20%, and arsenic grade is about 4.5%. The comprehensive utilization technology of this cyanide residue is carried out, and the gold in the cyanide residue is recovered twice by roasting, acid leaching, cyanide leaching and flotation, so as to realize the resource utilization of hazardous waste of cyanide residue. The experimental data show that the leaching rate of gold after roasting is about 40%, and the leaching rate of gold can further improve the leaching rate up to 51.16%. The direct flotation effect of cyanide slag is very poor, and the highest grade of concentrate gold can reach about 20g / t, and the recovery rate is 57.73%.
