The fluorite-barite ore of Aouli, hosted in the Hercynian granite, was formed because of the mixing between a hot ascending deep-seated basinal brine …

To investigate the positive flotation separation of barite-type fluorite ore from fluorite, a mass ratio of 1:1 for fluorite and barite was established. On this basis, the impact of pH values and the dosage of α-BLA on the selective flotation was examined under the condition of starch as the inhibitor. 2.2. Test method

The decrease of fluorite floatability after pretreatment as shown by the test with the Hallimond tube ( Fig. 2) can also be noticed in the flotation of barite ore.
