Ultrasonic-assisted flotation of fine coal: A review ...

    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.

    The method evolved from continuous development of laboratory flotation tests that were then compared to the "Standard" methods. By continuous evaluation of results and observation, the method evolved to the 16th and final method. This was found to be robust and to equal or outperform all "Standard" methods on all coal types tested.

    The amount and quality of concentrate obtained from froth flotation of a coal are very important to determine the efficiency of the separation process. The shape and size of the bubbles in the froth directly affect the amount and purity of the concentrate overflowed during the froth flotation of the coal. The froth structure is significantly dependent on parameters such as the size of the ...
