摘　要: 19世纪中叶,欧、美一些国家开始建设重选厂,19世纪末建设磁选厂和浮选厂,20世纪40年代后,发展化学选矿。60年代以来,细粒重选、微细粒浮选、湿式强磁选和选冶联合流程得到发展并建厂。70年代以来,新工艺、新设备不断涌现,国外建成了大规模选矿厂,如巴布亚-新几内亚建成日处理矿石量115 000t选矿厂。

Abstract: During the middle of the nineteenth century,some European and American countries started the construction of gravity mill,at the end of nineteenth century the construction of magnetic separation and flotation plant factory was underway,and after the 1940 s,chemical processing technology was developed. Since the 1960 s,fine gravity,fine particle flotation,wet strong magnetic mineral separation and combination process of Mineral Processing and smelting have been developed and some plants have been constructed. new and processing and equipment have been constantly emerging since the1960 s,and large- scale mineral processing plants have been built,such as an ore dressing plant of115 000 t daily built in Papua New Guinea.
Keywords: Chemical processing; Gravity separation; Flotation; Magnetic separation
