一、前言金川镍冶炼生产过程中,产出的钴渣含钴金属每年约为100吨。十几年来对金川钴渣提钴工艺进行了一系列的研究。近几年来研究试验成功了钴渣→硫酸还原溶解→黄钠铁矾法除铁→P-204萃取除杂质和分离镍钴 I. Preface Jinchuan nickel smelting production process, the output of cobalt slag containing cobalt metal is about 100 tons per year. A decade of Jinchuan cobalt slag cobalt extraction process conducted a series of studies. In recent years, the successful research of cobalt slag → sulfuric acid reduction → dissolution of sodium ferrovanadium → P-204 extraction of impurities and the separation of nickel and cobalt
