根据苏联黑色冶金选矿研究设计院的设计,在列别金采选公司建设和投产了优质精矿选矿厂。该厂保证供应粉末冶金和蓄电池生产工厂的原料。 1983～1984年间,在优质精矿选矿厂进行了磁铁矿精矿的阴离子反浮选精选工艺的开工调试工作。按这一工艺,选矿厂取得了铁品位
According to the design of the Soviet Union Black Metallurgy Research and Design Institute, a high-quality concentrate concentrator was built and put into production at Le Sejin Mining and Dressing Company. The plant guarantees the supply of raw materials for powder metallurgy and battery production plants. During 1983 ~ 1984, the fine concentrate concentrator was carried out in the magnetite concentrate anti-flotation process of anti-flotation start debugging. According to this process, beneficiation plant made iron grade
