| 中文摘要: |
| 某萤石矿中萤石与石英密切共生。采用磨矿-浮选工艺流程进行选矿试验，虽然所得萤石精矿w（CaF2）达98%以上，但精矿中杂质w（SiO2）>1%。采用阶段磨矿阶段浮选工艺流程，获得了w（CaF2）=98.07%，w（SiO2）=0.77%的优质萤石精矿；粗精矿再磨使萤石充分单体解离，有助于降低浮选精矿中二氧化硅。 |
| 英文摘要: |
| In a fluorite deposit fluorite is closely associated with quartz. Test of grinding-floatation technology showed CaF2 grade > 98%. However the impurity of quartz in the concentrate is>1%. Application of stage grinding and stage floatation technology results in CaF2 grade =98.07%,SiO2=0.77%. Regrinding of the crude concentrate brings full liberation of fluorite and facilitates reduction of silica in the concentrate. |
