The authors provide insight into the problem of selective flotation of fluorite from quartz–fluorite ores. The flotation of fluorite mineral from ores by using acidized water glass as depressant has been studied for substitution of the commonly used depressant. It was found that the acidized water glass could achieve higher selectivity of fluorite minerals against gangue minerals in the fluorite flotation. The experimental results showed that YF collector has high selectivity in the flotation of fluoride for low-grade fluorite ores. The use of the YF collector also made it unnecessary to heat the pulp to a high temperature and achieved an acceptable reduction in the flotation temperature to [Formula: see text]C. The YF collector should be used in neutral pH to separate fluorite from gangue and it could also improve fluorite recovery and flotation rate.

在低温和中性 pH 条件下改善萤石浮选

作者深入了解了从石英萤石矿石中选择性浮选萤石的问题。研究了以酸化水玻璃为抑制剂从矿石中浮选萤石矿物，以替代常用的抑制剂。结果表明，酸化水玻璃在萤石浮选中对萤石矿物对脉石矿物的选择性更高。实验结果表明，YF捕收剂对低品位萤石矿的氟化物浮选具有较高的选择性。使用 YF 捕收剂还使得无需将矿浆加热到高温，并将浮选温度降低到 [公式：见正文]C 是可以接受的。
