摘　　要： 研究MSO-TBP组成的协萃体系从碱性氰化液中萃取金过程。结果表明,MSO-TBP体系在碱性氰化液中对金的萃取有较好的协萃效应,MSO的摩尔分数为0.8时,协萃效应系数达到最大,为165。体系能快速萃取金,在2min内已基本达到萃取平衡。即使在低相比下,体系对金仍有较高的萃取率。相比(O/A)为0.6时,金的萃取率达到94.7%。高碳醇对金的萃取影响较大,但只起助萃的作用。 The gold extraction process from alkaline cyanide solution with the synergic system consisted of MSO and TBP is studied. By the experimental results, there is the obvious synergic effect in this MSO and TBP system for gold extraction from alkaline cyanide solution. The maximum synergic coefficient, 165, is achieved at 0.8 of the molar fraction of MSO, The gold extraction is quickly in this synergic system, the extracting equilibrium can be built within 2 minutes. Even in low phase ratio, the gold extraction rate is still high, the gold extracting recovery is up to 94.7 % at phase ratio （ O/A） 0.6. The alcoholic H in long-chain molecule is of remarkably effect on the gold extraction, however, it only plays an assistant role in extraction process.
