Improving Low Rank Coal Flotation Using a Mixture of Oleic

The mixed collector can improve low rank coal flotation efficiency, but its synergistic mechanism needs to be further explored. In this paper, oleic acid-dodecane (OA–D), oleic acid (OA), and dodecane (D) were employed to treat the low rank coal for revealing new synergistic mechanism of the mixed collector. First the surface free energy of the coal, the surface free energy of coal–water

Carrier Flotation of Low-Rank Coal with Polystyrene - MDPI

Froth flotation is an efficient method for the upgrading of fine coals of less than 0.5 mm [1,2,3].However, low-rank coals are very difficult to float with ordinary collectors (diesel oil, kerosene, etc.) due to abundant oxygenated functional groups on their surfaces, such as hydroxyl and carboxyl groups, which hinder the adsorption between low-rank coal particles and collectors [4,5].
