萤石和方解石浮选分离

Separation of Fluorite and Calcite by Flotation

碳酸盐类萤石矿石含ＣａＣＯ３量高，往往因萤石和方解石分离效果差而得不到合格的酸级精矿。文中针对此类矿石进行了大量的试验研究；介绍了捕收剂和调整剂的选择和使用，并列举了两个高ＣａＣＯ３含量的萤石矿选别实例。

Fluorite carbonate ores have high CaCO3 content from which qualified concentrates can not be gained often because of the poor separation efficiency of fluorite and calcite. Extensive experimental research have been done on this type ores by the authors and the selection and application of collectors and regulators are described and two beneficiation cases of fluorite ores with high CaCO3 content are cited in the paper.
