Abstract:The extraction properties of precious metals by petroleum sulphoxide have been studies. An inte-grated solvent extraction method used to separate gold, palladium and platinum in distillated raffinate from Jingchuan Non-ferrous Metals Industry Companywas proposed, which sonsisted of the extractions of gold by DBC, palladium by PSO and platinum by N235.The percent extractions and strippings of Au,Pd and Pt have all come up to the standard of 99.99%.The rhodium and iridium mainly retained in the raffinate.

 

Key words: gold platinum palladium  solvent extraction separation
