萤石重晶石共生矿综合利用技术研究

摘要

A low-grade fluorite-barite ore from southeast of Chongqing municipality was determined as the object of this study. The result of the closed circuit test was satisfactory using the following flotation technological process which was based on the reseach of substance component and process mineralogy. Firstly, get the bulk concentrate about fluoritc and banle by bulk flotation. Secondly, recover fluorite from the bulk concentrate. And recover barite ore at last. The CaF2 grade of fluorite concentrate is 97.84% with the CaF2 recovery-rate 84.83%, the BaSO4 grade of barite concentrate is 92.68% with the BaSO4 recovery-rate 80.67%.%以渝东南某低品位萤石重晶石共生矿为研究对象,在物质组成和工艺矿物学研究的基础上,采用“混合浮选-优选萤石-再选重晶石”的全浮选工艺流程,获得了满意的技术指标:萤石精矿CaF2品位97.84％,回收率84.83％;重晶石精矿BaSO4品位92.68％,回收率80.67％.
