中国科学院化工冶金研究所与天津市熔炼厂合作研究的P-204萃取除杂,季胺氯化物萃取分离钴镍处理含钴、镍废合金的工艺已于四月十一日在天津通过鉴定。鉴定意见认为:实际应用季胺来分离镍钴在国内实属首创。季胺萃取分离钴镍酸碱消耗少,对温度、溶液中氯离子浓度及pH值要求均不 Institute of Chemical Metallurgy, Chinese Academy of Sciences and Tianjin Smelting Plant cooperation in the study of the P-204 extraction impurity, quaternary ammonium chloride extraction and separation of cobalt and nickel alloy containing cobalt and nickel scrap process has been identified in Tianjin on April 11 in Tianjin. Identification of the opinion that: the actual use of quaternary ammonium to separate nickel and cobalt is the first in the country. Quaternary amine extraction and separation of cobalt and nickel acid consumption less alkali, the temperature, the chloride concentration in the solution and the pH value requirements are not
