文章介绍了我国某稀土矿的矿物组成、嵌布特性。根据矿物嵌布特征与共生矿物的可选性差异,拟定了混合浮选—优先浮选稀土的工艺流程。该流程的实质是在中等碱性介质(pH=9～10)采用氧化石腊皂作捕收剂,水玻璃作铁矿物硅酸盐矿物的抑制剂,把萤石稀土方解石等易浮矿物混合浮选在一起,使其与铁 This paper introduces the mineral composition and inlaid properties of a rare earth mine in China. According to the differences between the mineral embedded features and the intergrowth minerals, a mixed flotation-preferential flotation rare earth process was proposed. The essence of the process is the use of paraffin wax soap as a collector in medium alkaline medium (pH = 9 ~ 10), water glass as an inhibitor of iron mineral silicate minerals, fluorite rare earth calcite and other easily floating minerals Mix flotation together to make it with iron
