1981年夏,金川公司根据第三次科研会议决定,完成了P_(507)萃取分离钴镍小型试验和扩大试验,接着开展了应用高效分离钴镍萃取剂2—乙基已基磷酸单脂(简称P_(507))代替P_(204)萃取分离钴镍半工业试验,取得了满意的结果。为了将该项研究成果用于工业生产,北京有色冶金设计研究总院正在对钴车间设计作相应的修改。
In the summer of 1981, according to the decision of the third scientific research meeting, Jinchuan Company completed the P_ (507) extraction and separation of cobalt and nickel small-scale experiment and expansion test, followed by the application of high-efficient separation of cobalt-nickel extractant 2-ethylhexyl phosphoric acid monoester Referred to as P_ (507)) instead of P_ (204) extraction and separation of cobalt and nickel semi-industrial test, and achieved satisfactory results. In order to use the research results for industrial production, Beijing Nonferrous Metallurgical Design and Research Institute is making corresponding changes to the design of the cobalt workshop.
