| Abstract: | Magnesite is one of superior mineral resources in China. It has been widely used in metallurgy, building industry, chemical industry etc. High-silicon magnesite (SiO2＞3%, mass fraction) is one of low-grade and difficult-to-select magnesite with high content of SiO2. High-quality magnesia products are prepared from high-silicon magnesite by flotation. By direct calcination of high-silicon magnesite with reasonable ingredients, high value-added refractory materials such as magnesia-silica, forsterite and composite powder materials are prepared. Important raw materials such as building materials and chemical materials are also prepared from high-silicon magnesite. Hence high-silicon magnesite has high economic and scientific research value. In the paper, the purification processes of high-silicon magnesite at home and abroad were reviewed. The purification principles and technical indicators were expounded. Finally the comprehensive utilization of high-silicon magnesite were introduced. |
