摘要
进行了某富硫高砷金精矿加添加剂CL硫脲浸金试验研究。试验研究结果表明,添加剂CL可以改善硫脲浸金过程,降低浸出所需的硫脲浓度,提高金浸出率,可使该金精矿的金浸出率达到89%以上。试验还探讨了浸出的最佳条件,并分析了添加剂CL对浸金机理的影响。
The investigation of thiourea leaching gold by adding the additive （CL） from the refractory gold concentrate containing sulphur and arsenic was presented. The results showed that the CL could improve the process of thiourea leaching gold, reducing thiourea concentration and increasing leaching gold recovery. The leaching gold recovery of the gold refractory concentrate could reached over 90%. The optimal conditions and mechanism of leaching gold in existence of CL have been studied as well.
