摘　　要：报道了一种用于硫脲法浸金过程的新的Re - 1型溶金添加剂 ,实验证实该添加剂可以改善硫脲浸金液状态 ,降低浸液硫脲浓度 ,提高金浸出率。可使含砷硫化原生矿的一次金浸出率达到 89%以上。同时 ,测定了工艺的最佳条件并讨论了Re -A new additive of dissolving gold using the process of thiourea leaching gold has been reported.It was comfirm through tests that the additive can improve conditions of thiourea solution,and increase leaching rate of gold under low concentraction of thiourea in leaching solution.It can been reached above 89% of leaching rate for gold in of the containing arsenic raw ore.The optimal conditions of the technology and mechanism of leaching gold in existence of Re-1 have been studied as well.
