中文摘要: 采用硫脲法浸金工艺对某难处理氰化尾渣进行浸出试验。结果表明,在液固比3∶1,pH=1~1.5,硫脲浓度2 kg/t,温度60 ℃,浸出时间6 h时,金浸出率可达82.30%。
Abstract:The cyaniding tailing of refractory gold ore was leached with thiourea process. The results show that the extraction rate of gold can reach 82.30% on the conditions including ratio of liquid to solid of 3∶1, pH of 1~1.5, thiourea concentration of 2 kg/t, temperature of 60 ℃ and leaching time of 6 h.
