| 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.

| Abstract: | In a fluorite deposit fluorite is closely associated with quartz. Test of grinding-floatation tech- nology showed CaF2 grade 〉98%. However the impurity of quartz in the concentrate is〉1%. Applica- tion of stage grinding and stage floatation technology results in CaF2 grade =98.07% ,SiO2 =0.77%. Re- grinding of the crude concentrate brings full liberation of fluorite and facilitates reduction of silica in the concentrate |

| Keywords: | fluorite mine stage flotation stage grinding reduce the silica content |
