Open publisher page 0 citations

Abstract

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 flotationis studied to remove impurities and gain good technical index in this paper.
