廿世纪前有色金属矿石和铁矿石都是由冶炼厂直接进行加工处理,首先是南非的金矿需要将矿石磨细后选取细颗粒的黄金,随后因高品位的有色金属矿石越来越少和浮游选矿法的发展,细磨工艺在有色金属工业中才获得普遍地应用。铁矿石的选别处理比较晚,廿世纪四十年代末期才开始半工业试验,而在五十年代初期才有大规模工业生产选别铁燧石的选矿厂。

Before the twentieth century, non-ferrous metal ores and iron ores were directly processed by the smelter. The first is that the South African gold mines need to finely ground the ore to select the fine-grained gold, and then the fewer and fewer high-grade non-ferrous metal ores And the development of floatation beneficiation, fine grinding process in the non-ferrous metal industry was generally applied. Iron ore sequestration was relatively late, and only semi-industrial tests were started in the late 1940s. In the early 1950s, large-scale industrial production of iron cherts was selected.
