| 摘 要： | 本文对Ｒ－３２和１－５的二种催化剂（含Ｐｔ≈０．３％）回收铂的工艺进行了实验室研究。采用高温焙烧－盐酸＋氧化剂浸出－溶剂萃取铂新工艺。一次浸出作业可使废渣含Ｐｔ降至５０ｇ／ｔ以下，用Ｎ２３５萃取代替现行的锌粉置换，铂回收率可提高１％以上；用水解法精制后，可获得９９．９８％铂产品，实收率９７％以上。

| Abstract: | A new recovery process of platinum from two kinds of wasted catalysts by using high temperature roasting-HCl leaching with an oxidant-solvent extraction has been experimented at lab.by one stage of leaching.The content of Pt in the residueis is less than 50g/t.Pt recovery effeciency can be enhanced above 1% by N235extraction in place of Zn replacement method.99.98% Pt products can be obtained by hydrolysis refining and the recovery can be up to above 97%. |
