我国磷矿资源丰富,类型齐全,但多属于中低品位的磷矿石。魂已探明的大中型磷矿床中,多数为沉积块岩矿床。其矿石必须经过选矿,才能满足生产要求。为了合理选矿工艺和评价选矿效果,上海化工研究院、化工矿山设计研究院、南京土壤研究所等单位,经过三年的努力,完成了《我国磷矿石物质组成和结构研究》,取得了新的进展。
China’s phosphate rock is rich in resources and complete in type, but most of them belong to low-grade phosphate rock. Soul has proven large and medium-sized phosphate deposits, the majority of sedimentary rock deposits. Its ore must go through dressing, in order to meet the production requirements. In order to rationalize beneficiation process and evaluate beneficiation results, Shanghai Chemical Industry Research Institute, Chemical Mining Design and Research Institute, Nanjing Institute of Soil Science and other units, after three years of hard work, completed “China’s phosphate rock composition and structure of the study,” made new Progress.
