菱镁矿浮选作用机理研究

Mechanism of Research On Magnesite Flotation

菱镁矿是一种重要的非金属矿资源,广泛应用于冶金、建材、化工等行业。低品级菱镁矿不能直接作为煅烧优质耐火材料的原料,而高品级的菱镁矿随着不断开采,储量越来越少,因此低品级菱镁矿的利用已势在必行。目前菱镁矿浮选应用最多的为阳离子反浮---阳离子正浮流程,阴离子反浮选主要捕收剂为油酸系列。

Magnesite is a very important non-metallic mineral. And it is widely applied in metallurgic, building materials, chemical industry and so on. Low grade magnesite can＇t be used directly as material of refractory, and along with the continuously mining, the reserves of high grade magnesite becomes less and less. Therefore, for better utilization the resources, it is necessary to find a purification method, which is suitable for low grade magnesite.
