碳酸盐岩的矿物单体解离研究进展

Research Progress in the Dissociation of Mineral Monomers in Carbonate Rocks

碳酸盐岩主要是由沉积的碳酸盐矿物组成,还混杂有陆源矿物、黏土等。但将碳酸盐岩中的矿物单体解离出来却非常困难,综述了目前使用浮选法、重选法、磁选法、化学法解离碳酸盐岩中的矿物的研究现状,分析了这几种方法的优缺点,阐述了助磨剂和微波加热技术在矿物单体解离上的应用。并对几种分离方法进行了展望。

Carbonate rocks are mainly composed of sedimentary carbonate minerals, mixed with terrestrial minerals, clay and so on. However, it is very difficult to dissociate the mineral monomers from the carbonate rocks. In this paper, present research status of dissociating the mineral monomers in the carbonate rocks by using flotation, gravity separation, magnetic separation and chemical separation methods was reviewed. The advantages and disadvantages of these methods were analyzed. The application of grinding aid and microwave heating technology in the dissociation of mineral monomers was described. At last, development trend of several separation methods was prospected.
