Abstract:The resarch has been done on recovery of valuable metals from the waste alloy contained Co, Ni and Cr in relative high content. By adopting the flowsheet of acid leaching with air injection combined with P204 ex-traction for purification and separation, 84. 6 %Co was recovered. The final product of CoO powder in high quality was achieved and also the NiO could be obtained.

 

Key words: acid leaching with air injection  p204 extraction  recovery of Co and Ni
