In this paper, the experimental study on improving quality and reducing impurities of a fine-grained fluorite flotation concentrate that is difficult to be separated with the high gradient magnetic separator is introduced. Under the condition that grinding size smaller than 0.013 mm accounts for 70%, the magnetic separation tests were carried out to flotation concentrate at different field strengths with high gradient magnetic separator in laboratory. The test results showed that the mineral content of fluorite gradually increased, the more the magnetic impurities were removed as well as the productivity of non-magnetic products and recovery rate of fluorite decreased with the increase of magnetic field strength, the mineral content of fluorite in concentrate increased from 84.97% to 93.63% and recovery rate was 59.51% when magnetic field strength was 1.7 T. The optimal conditions for improving quality and reducing impurities of fluorite concentrate are proposed, which are with the important guiding significance for actual productions.
