经红外光谱测试及单矿物化学分析，确定了磷灰石的种类；通过显微镜观察，系统地研究了不同自然类型磷矿石中磷灰石的嵌布嵌镶关系；利用线测法测定了磷灰石的嵌布粒度；采用一粗一精一扫浮选流程，按原来的浮选条件和药剂制度所得精矿，研究了其单体解离度及选矿回收率；提出了改进选矿工艺流程的可能途径和方法。
Through the infrared spectroscopy and single mineral chemical analysis to determine the type of apatite; microscopically observed apatite embedded in different natural types of phosphate rock mosaic relationship; measured by the method of phosphorus Gray scale embedded grain size; using a coarse and a fine swept flotation process, according to the original flotation conditions and the pharmaceutical system of the concentrate, the study of its monomer dissociation and beneficiation recovery rate; proposed to improve the beneficiation process Possible ways and methods.
