| Abstract: | A integrated solvent extraction used to separate precious metals in distillated raffinate from Jingchuan Non-ferreous Metals Industry Company was proposed, which consisted of the separation of precious metals and base metals,the extraction of gold by DBC, the extraction of palladium or co-extraction of platinum and palladium by a new extractant,and the extraction of iridium by TBP.A solution containing rhodium was finally obtained.The recovries of gold, palladium, platinum,rhodium,and iridium were more than 99,98, 97, 95 and 90%respectively. |
