Taken a carbonate disseminated gold ore in Jiangxi province as an object, experiments of direct cyanide leaching and roasting - cyanide leaching were carried out. Experimental results showed that the leaching rate of gold was 86.27% for the arsenic - sulfur gold under the condition of the grind size of the run - of - mine ore -0.074 mm 50% , roasting temperature 550 ℃, roasting time lh, concentration of NaCN 0.10% and cyanide leaching time 48h.关键词
