内蒙古萤石资源丰富,质量好,为国内重要产地,也是自治区换汇主要矿产品。多年来,多数矿山进行土法开采,手选块矿销售与出口,富尾矿未加处理,资源利用率极低。如化德萤石矿手选尾矿一般含CaF_2 60—40％,平均达50％以上。露采手选方法对中小型矿山初期生产来说,因投资甚少,收 Inner Mongolia, fluorite is rich in resources, good quality, an important place of origin, but also the major mineral products exchange vents. Over the years, most mines have been exploited by native law, selling and exporting hand-chosen block mines, untreated rich tailings, and very low resource utilization rates. Such as the German-fluorite mine hand tailings generally contain CaF 2 60-40%, an average of 50% or more.
