Flotation Plant Coal

Coal flotation is a separation process performed mainly based on differences in surface hydrophobicity between coal and gangue The flotation reagent can improve the hydrophobicity of coal and also the adhesion between coal and air bubbles Kerosene and light diesel oil are widely used as collectors in coal flotation
