The flotation of artificially mixed minerals confirmed that an efficient separation of fluorite from calcite could be achieved using the reagents scheme of HPS/NaOl.

A certain amount of deionized water and designed flotation reagents were added into 0.1 g of mineral sample, and stirred for 30 min to ensure adsorption equilibrium at a slurry pH of 6.0. Then the residual collector concentration in the supernatant was measured and the NaOL adsorption capacity of mineral surface was calculated through Eq.

The efficiency of the flotation process is a function of the probability of particle-bubble collision, particle-bubble attachment, and particle-bubble detachment. Froth flotation is an extensively accepted separation technique where the separation characteristics depend on narrow particle size range between approximately 10–100 μm.

This solves the problems of high consumption of flotation reagents and low flotation efficiency [108]. In addition, pretreatment methods, such as microwave [109], pyrolysis [110], hydrothermal [111], pore compression [112], and pre–wetting/immersion treatment [113], can also improve the floatability of residual carbon.
