中文摘要: 对某含砷金矿采用与软锰矿混合酸浸预处理浸金,通过正交试验研究反应温度、反应时间、硫酸浓度、液固比、软锰矿与含砷金矿质量比对金浸出率的影响。结果表明,在下述最优条件下,砷脱除率和金浸出率分别为85.83%、93.57%:反应温度150 ℃、反应时间3 h、软锰矿与含砷金矿质量比2.0、硫酸浓度10 mol/L、液固比2︰1。
Abstract:Arsenic-bearing gold mine was acid leaching pretreated with pyrolusite to remove arsenic and leach gold. The effects of reaction temperature, reaction time, vitriol concentration, ratio of liquid to solid (L/S), and mass ratio of pyrolusite to gold mine (mpg) on gold leaching rate were investigated by orthogonal test. The results show that arsenic removal rate is 85.83% and gold leaching rate is 93.57% under the optimum conditions including reaction temperature of 150 ℃, reaction time of 3h, mpg=2, H2SO4 concentration of 10 mol/L, and L/S=2.
