中文摘要: 在有氧化剂存在的条件下,采用硫脲酸性浸出难浸金矿中的金,并考察了各种影响金浸出率的因素。结果表明,最佳浸金条件是:硫酸初始浓度1.3 mol/L、硫脲浓度14 g/L、硫酸铁浓度24 g/L、液固比10∶1、浸出时间10 h,金浸出率可达80%左右。
Abstract:Gold was acidic leached from refractory gold ore with thiourea and oxidant. The factors affecting gold leaching rate were investigated. The results show that the gold leaching rate is about 80% under the optimum conditions including initial sulfuric acid concentration of 1.3 mol/L, thiourea concentration of 100 g/L, ferric sulfate concentration of 100 g/L, ratio of liquid to solid of 10∶1, and reaction time of 10 h.
