萤石与方解石的分离,无论在理论上或是实践上都被认为是困难问题之一。近年来,我们对浙江东风萤石矿矿石进行了在不同药剂制度下萤石与方解石、石英之间浮选分离的研究。结果表明,由于碳酸钙和萤石之间可浮性差别很小,在碱性介质中浮选分 Fluorite and calcite separation, both in theory and practice are considered to be one of the difficult issues. In recent years, we studied the flotation separation of fluorite, calcite and quartz in different chemical systems in Zhejiang Dongfeng fluorite ore. The results show that, due to the difference between the floatability of calcium carbonate and fluorite is very small, flotation in alkaline medium
