Abstract
Based on characteristics of the rare earth tailingsthat the grade of the fluorite and barite is relatively low and the degree of liberationis relatively high,through experimental research,fluorite and barite were recovered by flotation technology of fluorite-baritemixed flotation-fluorite-barite flotation separation-reverse flotation of barite concentrate.EMLB-1 and EMLY-1 researched by Iustitute of Multipurpose Utilization of Mineral Resource was applied.EMLB-1 could collect fluorite and batite,EMLY-1 could depress batite in floatation separation between fluorite and batite.Inreverse flotationof barite concentrate,the test effect was improved by depressing barite and adopting NaF to activate coal gangue.Finally,the fluorite concentrate with CaF2grade of 97.33％,BaSO4of 0.03％ and the recovery of 74.40％ and thebatite concentrate with BaSO4 grade of 90.42％,BaSO4of 2.65％ and recovery of barite 90.12％ were obtained.关键词
