前言现时,国内外从铜镍付产品中提取金,一般都是将金转入溶液用硫酸亚铁、二氧化硫、草酸还元或者将金铸成阳极电解等方法。方法可行,缺点是生产周期长,操作繁杂,试剂消耗大,成本高等。七十年代初,采用溶剂萃取技术分离和提纯金开始引起冶金工作者的热烈兴趣,复旦大学与上海冶炼厂,厦门大学与邵武冶炼铜厂,研究了 Preface At present, at home and abroad to extract gold from copper and nickel to pay products, are generally transferred to the solution of gold with ferrous sulfate, sulfur dioxide, oxalic acid or cast gold anode electrolysis and other methods. Method is feasible, the disadvantage is the long production cycle, complex operation, reagent consumption, high cost. In the early seventies, the use of solvent extraction technology to separate and purify gold began to attract the enthusiastic metallurgical workers, Fudan University and Shanghai Smelter, Xiamen University and Shaowu smelter copper, studied
