Abstract

Abstract

The chemical composition,mineral composition,dissemination characteristics and grain size composition of Fluorite-barite ore in Chongqing were investigated through chemical analysis,XRD,optical microscope,EPMA and MLA.The results showed that:The useful minerals are fluorite and barite in the ore,its content respectively is 25.51%and 60.14%,the gangue mineral mainly is the calcite,about 10% content.In addition,there are quartz,dolomite,olivine and so on,but their content is very low,the effect on the ore properties can be ignored.The hardness of the ore is low,fluorite,barite and calcite mosaic are mosaic and interlocking with each other,by the way,their particle size is large,fine grinding is needed to make the mineral dissociate better.This will lead to the grinding of fluorite and barite,resulting in serious ore mud,and then,affect the concentrate taste and recovery.The results provide an important basis for the comprehensive utilization of the fluorite-barite ore.
