摘要
Abstract
This study investigated a fluorite deposit from Jiangxi Province using multi-element analysis and a Mineral Parameter Automatic Analysis system(BPMA)to conduct process mineralogy research,combined with flotation tests to systematically evaluate its beneficiation potential.The results of process mineralogy show that the CaF2 grade of the ore is 40.37%,and the main gangue minerals are quartz,orthoclase,sericite,and high-temperature albite.Fluorite mainly occurs in a vein-type form,and its intergrowth relationship with gangue minerals is relatively simple.Under the optimized conditions of grinding fineness(70%passing-0.074 mm)and reagent scheme(1500 g/t sodium carbonate,1500 g/t sodium silicate,and 200 g/t oleic acid),a closed-circuit flotation process consisting of one roughing,five cleaning,and one scavenging stage was adopted.A fluorite concentrate with a CaF2 grade of 97.41%and a recovery of 92.77%was obtained.According to the YB/T 5217-2019 standard,the concentrate meets the requirement of first-grade fluorite concentrate(FC-97).The results provide a technical reference for the development and utilization of similar fluorite resources.关键词
