Abstract: In order to determine a reasonable beneficiation process for a fluorite mine in Jiangxi,a systematic process mineralogy and flotation test are carried out for the separation problemof fluorite and gangue minerals in the ore.The test results show that under the conditions of grinding fineness of -0.074 mm 70%,rough sodium carbonate dosage of 1 000 g/t,sodium silicate dosage of 1 500 g/t and oleic acid dos⁃ age of 200 g/t,the fluorite concentrate with CaF2 grade of 98.12% and CaF2 recovery of 93.02% is obtained by using a closed-circuit test process of one roughing,five cleaning and one scavenging.The concentrate quality meets the requirements of YB/T 5217-2019 super grade products.

Key words: fluorite, process mineralogy, quartz, flotation, super grade products
