| 摘 要： | 在浮选新工艺中，使用两性捕收剂６ＲＯ－１２和新型抑制剂ＲＰＯ３，对萤石浮选进行了研究，当原矿品位为３０．２５％ＣａＦ２、３６．２％ＳｉＯ２、２．１２％ＣａＣＯ３时，可得品位为９７．３５％ＣａＦ２、１．５８％ＳｉＯ２、０．４３％ＣａＣＯ３，回收率为６８．６％的萤石精矿，光电子能谱研究表明，ＲＰＯ３抑制方解石的机理在于，ＲＰＯ３能在脉石表面发生化学吸附或化学反应。

| Abstract: | Amphoteric collector 6RO-12 and new depressant RPO 3 are of good selectivity .Flotation separation of fluorite ore was conducted by a special flotation flowsheet using 6RO-12 as a collector and RPO 3 as a depressant. The results show that fluorite concentrate containing 97.35% CaF 2,1.58% SiO 2 and 0.43% CaCO 3 can be obtained from feed containing 30.25?F 2 ,36.2% SiO 2 and 2.12% CaCO 3,with a CaF 2 recovery of 68.6 %. The action mechanism of RPO 3 was studied with X-ray photoelectron spectra .It shows that adsorption and chemical reaction of RPO 3 on calcite surface result in depression of calcite . |
