摘要
介绍了多种含金溶液体系的金萃取研究现状及进展,包括卤化物(主要是氯化物和溴化物)体系、氰化物体系、酸性硫脲体系和多硫化物体系等,并对各种萃取剂萃取金的效果、优缺点进行了表述,总结了各种含金溶液体系中颇有前景的一些萃取剂的发展优势。
The progress and current status of research on gold solvent extraction in a variety of gold solution sys-tems,such as halide（ chloride and bromide mainly） ,cyanide,acidic thiourea and polysulfide system,are introduced in this paper.The advantages and disadvantages of gold extraction with different extraction agents are described and the advantages of several promising agents in different gold solution systems are summarized.
