摘    要：采用鼓风酸浸、P₂₀₄萃取除杂、P₂₀₄萃取分离钴、镍的工艺流程，对钴、镍、铬含量较高的合金废料实行了综合回收，钴的回收率达84.6%。采用该流程可快、省、优地生产出合格的氧化钴粉和综合回收氧化亚镍。

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.
