我国辽吉地区蕴藏大量的内生硼矿床,其中有相当一部分矿石类型为硼镁石矿。其主要组成矿物为硼镁石和蛇纹石,两者合计约占矿石中矿物总量的80～90％以上。 硼镁石与蛇纹石同其它氧化矿物和硅酸盐矿物相比,有较弱的亲水性,因此具有较高的自然可浮性,研究硼镁石与蛇纹石的表面性质和可浮性,对分离这两种矿物以及综合利用硼镁石型矿石具有重要意义。本文通过对硼镁石和蛇纹石电动性质的研究,讨论两种矿物的表面特性,浮选药剂与矿物表面作用机理及它们同矿物可浮性的关系。
Liaoji region in our country contains a large number of endogenous boron deposits, of which a considerable part of the ore type of boehmite ore. Its main mineral composition is boehmite and serpentine, which together account for about 80-90% of the total amount of minerals in the ore. Magnesite and serpentine have weaker hydrophilicity than other oxidic and silicate minerals and therefore have high natural floatability. The surface properties of porphine and serpentine can be studied. Floating, the separation of these two minerals and the comprehensive utilization of boehmite ore is of great significance. In this paper, the study on the electric properties of magnalite and serpentine discusses the surface properties of the two minerals, the mechanism of their interaction with flotation agents and their relationship with the flotability of minerals.
