The tailings of an iron mine in Baotou, Inner Mongolia, contain fluorite resources with large reserve and low CaF2 grade. Unfortunately, the gangue minerals in the tailings, such as ankerite, calcite and barite, share similar floatability with fluorite, resulting in difficulty in fluorite recovery. With DKCS, FX-1 and starch introduced to depress ankerite, calcite and barite respectively, fluorite can be effectively separated from gangue minerals with modified oleate acid FH as the collector. It is shown that a closed-circuit test can result in a fluorite concentrate grading 90.68% CaF2 at 64.69% recovery, showing a comprehensive recovery of fluorite resources from the tailings.
