Abstract

Abstract

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.
