摘要: 采用化学分析、偏光显微镜分析、X射线衍射分析等一系列测试手段,对河南驻马店云母矿石的工艺矿物学特征进行了研究。研究结果表明,该云母矿石SiO2和Fe2O3含量较高,目的矿物是白云母,杂质矿物主要为石英和黑云母,且白云母片层中常夹杂有细粒的电气石。根据工艺矿物学研究结果,指出该矿石的开发方向是生产云母粉,但仅通过简单的破碎和筛分不能获得合格的云母粉产品,而必须进行较复杂的选矿加工,其技术路线是利用磁选去除黑白云母和电气石,利用浮选去除石英,并需考虑剥片处理。

Abstract: The process mineralogy of the mica mineral in Zhumadian Henan Province was studied by chemical analysis, polarizing microscope, X-ray diffraction and other testing methods.The results indicate that the mica mineral has the high concentration of SiO2 and Fe2O3, objective mineral is muscovite, and most of the gangue mineral are quartz and biotite.Fine tourmaline exists in the mica layer.According to the process mineralogy, the minerals which are only crushed and screened can't be used, and complex mineral separation must be carried out.The mineral processing technology is which biotite and tourmaline can be removed by magnetic separation, quartz can be removed by flotation, and may be treated by peeling .
