通过系统的岩矿鉴定、电镜扫描、X光衍射分析、红外光谱分析等综合方法,确定放马山矿段第三矿层的磷酸盐矿物为微～细晶碳-氟磷灰石,镁赋存于白云石和镁方解石中。通过对碳-氟磷灰石的嵌布粒度 嵌布类型和嵌镶特性等的系统研究和测定,以及对选矿产物的检测,为这一类型矿床的开发利用提供了矿物学、矿石工艺矿相学的基础资料,对探讨矿床成因也具有启示性作用。 Through the systematic identification of rock and mine, scanning electron microscopy, X-ray diffraction analysis, infrared spectroscopy and other integrated methods to determine the phosphate rock Mine No. 3 ore deposit is micro-fine-grained carbon-fluorine apatite, magnesium deposit In dolomite and magnesium calcite. Through the systematic study and determination of the embedded grain size and mosaic characteristics of carbon-fluo apatite, as well as the detection of beneficiation products, it provides mineralogy and ore technology for the development and utilization of this type of deposit. The basic information of the study also has an enlightening role in exploring the genesis of the deposit.
