低品位贵金属物料提取的难度主要体现在贵金属成分从很低品位的物料中有效地富集及各贵金属元素从多元贵金属混合料中高效分离方面。介绍了采用Na2CO3焙烧法从低含量Pt、Pd、Rh废料中有效富集铂族金属，富集后的富料氧化造液，用溶剂萃取法实现Pt、Pd、Rh的高效分离和初步提纯。

It is difficult to extract precious metals from low grade materials, and mainly reflect in two aspects:concentration and separation. The paper reports a soda roasting-solvent extraction process for the recovery of platinum group metals from waste materials, which containing trace amounts of Pt, Pd and Rh, Platinum group metals were concentrated effectively by soda roasting procedure, then dissolved into solution and separated selectively by solvent extraction.
