摘　　要：我国菱镁矿以量大质优闻名于世。长期以来由于弃贫采优的采矿方式,造成我国高品位菱镁矿资源日益减少,大量的低品位菱镁矿被废弃堆存未得到有效利用,造成资源的巨大浪费。本文针对国内某低品位菱镁矿的特点,通过"一次磨细——磁选——反浮选——正浮选"工艺流程,对低品位菱镁矿选矿脱杂进行了探索试验,取得了较好的技术指标。Magnesite in China is known in the world as reserve and quality, however high grade magnesite is decreasing because of detrimental mining method that has been lasting for years, and a large amount of low - grade magnesite is abandoned and stacked resulting in a huge waste of resources. For the mineralized and mineralogical features of the low grade magnesite in our country, the process of ＂one fine grinding - magnetic concentration - reverse flotation - positive flotation＂ is studied to remove impurities and gain good technical index in this paper.
