摘　　要：菱镁矿是我国重要的优势矿产之一,随着菱镁矿资源的不断开发利用,优质菱镁矿石开始短缺,而大量低品位菱镁矿石被丢弃,加强低品位菱镁矿石的分选提纯,以及对其高附加值产品的开发十分必要。综述了浮选法、化学处理法两种菱镁矿分选提纯方法,尤其详细阐述了浮选药剂、浮选工艺、化学处理方法等研究进展,介绍了国内外利用菱镁矿制备优质耐火材料、新型建筑材料、精细化工材料等的研究进展,为菱镁矿高效利用提供参考。Magnesite is one of the important advantageous minerals in China.With the continuous development and utilization,high-quality magnesite ore began to be in shortage,and a large number of low-grade magnesite ores were discarded.Therefore,it is necessary to enhance the separation and purification of low-grade magnesite ores and develop methods for their high-value-added products.This paper summarizes two methods for magnesite purification,namely flotation and chemical beneficiation.In particular,the research progresses of flotation reagent,flotation process and chemical treatment are described in detail.Besides,this paper also reviews the research progress of application of magnesite in high-quality refractories,new building materials and fine chemical materials at home and abroad.This paper could provide a reference for a new way of efficient utilization of magnesite.
