当前硅钙质磷块岩矿石的选矿仍以浮选为主要的方法。浮选过程的高效率,取决于高效的浮选药剂、合理的流程结构和完善的浮选设备这三个要素。药剂和设备在浮选过程中的重要性已为人们所认识并进行了大量的研究,但对浮选流程结构本身,研究的却不多。我国的一些胶磷矿可选性研究报告就 The current mineral processing of Si-Ca phosphate rock ore still flotation as the main method. The high efficiency of flotation process, depends on the efficient flotation reagents, reasonable process structure and improve the flotation equipment of these three elements. The importance of pharmaceuticals and equipment in the flotation process has been recognized and much research done, but the structure of the flotation process itself is not much research. Some studies on the selectivity of collodion in our country
