摘　　要：在H2SO4体系中,以氧气作为氧化剂,采用加压氧化浸出处理钴白合金。试验结果表明该工艺是可行的。在优化条件下,钴、镍、铜的浸出率分别为Co>98%、Ni>98%、Cu>95%,铁大部分留在了渣中,溶解率小于5%。It is demonstrated by this paper that it is feasible to deal with cobalt white alloy by pressure leaching using oxygen as oxidant in H2SO4 system. Under optimum leaching conditions, the leaching rates of cobalt, nickel, copper and iron are over 98% , over 98% , over 95% and less than 5% respectively.
