一、前言世界上用离析法处理难选氧化铜矿的研究始于1923年,至今已有五十多年的历史了。三十年代以后,由于世界资本主义的经济危机,铜价下跌,离析法的研究工作基本上停顿了二十多年之久。到五十年代,世界资本主义扩军备战,铜的需要量大大增加,这样,铜离析法才又引起重视。除了对此工艺技术问题进行研究外,六十年代开始还进行了大量的理论研究工作;在赞比亚和毛里塔尼亚建起了铜离析的生产厂。日本在秘鲁建了一个大型工业试验厂。
I. Preface The world study on the treatment of refractory copper oxide by segregation began in 1923 and has been in existence for more than 50 years. After the thirties, due to the economic crisis of world capitalism, the price of copper dropped, and the research on separation law basically stopped for more than two decades. By the 1950s, with the expansion of capitalism in the world for its preparations for war, the demand for copper increased greatly. As a result, the copper segregation law paid more attention. In addition to conducting research on this technology issue, a great deal of theoretical research began in the 1960s and a copper isolation plant was established in Zambia and Mauritania. Japan built a large industrial pilot plant in Peru.
