中文摘要: 贵州某难浸金矿原矿直接浸出率约15%,通常需在650 ℃以上进行焙烧预处理。为提高该金矿的浸出率,在加入氧化钙的条件下进行低温焙烧预处理试验,考察焙烧温度、氧化钙用量、焙烧时间对金浸出率的影响。结果表明,在下述最佳预处理条件下金浸出率可达85%以上:焙烧温度600 ℃,氧化钙用量17.5%,焙烧时间1.5 h。
Abstract:The direct gold leaching rate of one refractory gold ore in Guizhou Province was about 15%. Refractory gold ore is usually pretreated with roasting at 650 ℃ plus. In order to improve the gold leaching rate, the gold ore was pretreated with low temperature roasting with addition of calcium oxide, and the effects of roasting temperature, dosage of calcium oxide and roasting time on gold leaching rate were investigated. The results show that the gold leaching rate is over 85% under the optimum pretreatment conditions including roasting temperature of 600 ℃, dosage of calcium oxide of 17.5%, and roasting time of 1.5 h.
