研究了二烷基亚矾—胺从氰化物溶液中萃取金的反应中,亚矾和胺的化学结构以及萃取条件对萃金效果的影响。结果表明二烷基亚砜—仲胺体系在适当条件下可从较高pH(10～11)的氰化物溶液中有效地萃取金,并能与大多数共存金属元素达到很好的分离。此外,还具易于反萃的优点,是有应用前景的新型萃取体系。
The effect of the chemical structure of the sub-alum and the amine and the extraction conditions on the effect of gold extraction were investigated in the reaction of gold dialkyl-alum-amine from gold cyanide solution. The results show that the dialkyl sulfoxide - secondary amine system can effectively extract gold from cyanide solution with higher pH (10 ~ 11) under suitable conditions and achieve good separation from most coexisting metal elements. In addition, also has the advantage of easy stripping, is a promising new extraction system.
