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].
