【摘要】：作为国家战略型矿物,萤石在很多领域都有应用,对国家的经济建设非常重要。虽然我国的萤石矿储量位居世界前列,但年产量高、出口量大且独立矿床储产比低,这就使得在控制出口量的同时,如何提高伴生萤石矿物的回收率成为了目前急需解决的问题。随着易选的萤石矿日益枯竭,难选的伴生萤石矿受到了越来越多的关注,而由于萤石、重晶石和方解石分离困难,这类矿石也是世界公认的难选伴生萤石矿之一。目前尚缺乏对这类矿石的系统性研究,也没有适用于连续生产的分选方法。近年来对方解石-重晶石-萤石型矿石分选方法的研究主要集中在浮选和重选两个方面。文章从浮游选矿和重力选矿两个方面,对该类矿石的分选方法研究进展进行了综述,为进一步的研究提供参考。
[Abstract]:As a national strategic mineral, fluorite has been applied in many fields and is very important for national economic construction. Although China's fluorite reserves are among the highest in the world, the annual output is high, the export volume is large and the ratio of reserves to production of independent deposits is low, which makes it possible to control the export volume at the same time. How to improve the recovery rate of associated fluorite has become an urgent problem. With the depletion of easily separated fluorite ore, the refractory associated fluorite ore has attracted more and more attention. Due to the difficulty of separating fluorite, barite and calcite, these ores are also recognized as one of the refractory fluorite ores in the world. At present, there is no systematic research on this kind of ore and no separation method suitable for continuous production. In recent years, the separation methods of calcite-barite-fluorite ore are mainly focused on flotation and gravity separation. In this paper, the research progress of separation methods of this kind of ore is summarized from two aspects of flotation and gravity dressing, which provides a reference for further research.
