摘要: 菱镁矿作为我国优势矿产资源之一,广泛应用于冶金、建材、化工等行业。高硅菱镁矿(SiO2>3%,质量分数)是一种低品质菱镁矿,为难选菱镁矿矿石。采用浮选工艺可以制备出高质量的镁矿产品。将选后高硅菱镁矿合理配料后直接煅烧,可以制备镁硅砂、镁橄榄石及复合粉体材料等高附加值耐火材料,还可以制备建材、化工等原料,具有重要的经济意义和科学研究价值。本文对国内外高硅菱镁矿提纯工艺进行归纳,阐述其技术指标和提纯原理,最后介绍高硅菱镁矿的综合利用方法。

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.

Key words: high-silicon magnesite, flotation, refractory, active magnesia, low-grade magnesite, magnesite tailings
