目前,浮选是处理矿石的工业方法。但是,由于矿石质量恶化,仪采用浮选法是不能获得高质量精矿的,研究人员对含碳酸盐磷矿石的优先浮选给予了很大注意,制定了碳酸盐磷矿石优先浮选的新的药剂制度,然而,由于主要矿石——磷块岩和白云石的表面性质相似,它们的结构特点和细粒共生都使获得高质量磷精矿发生困难。根据矿石和矿物的自然特点,列宁格勒苏维埃工艺学院、国家矿物化学原料科学研究所、列宁格勒国家基础化学工业科学研究设计院和《磷块岩》合作工业公司共同制定
At present, flotation is an industrial method of processing ores. However, due to the deterioration of ore quality, flotation method is not used to obtain high-quality concentrate, researchers have given priority attention to flotation of carbonate-bearing phosphate rock and formulated carbonate phosphate priority However, due to the similar surface properties of the major ores - phosphorite and dolomite, their structural features and fine-grained symbiosis make it difficult to obtain high-quality phosphate concentrate. Based on the natural characteristics of ores and minerals, Leningrad Soviet Polytechnic Institute, National Institute of Minerals and Chemical Materials, Leningrad State Basic Chemical Industry Research Institute and Phosphorite Cooperative Industrial Company
