    Although iron pyrites and other minerals are removed from coal on an industrial scale almost exclusively by gravity separation methods at the present time, other beneficiation methods are coming into use. Among the developing methods, froth flotation (1,2,3) is the foremost, although the oil agglomeration method (4,5,6) is also promising. Both of these methods take advantage .

    Froth flotation is the most widely used method for beneficiation of fine coals. In flotation, the size of air bubbles is an important factor affecting the separation efficiency. The size of air bubbles generated by passing air through a bubble diffuser/sparger can be reduced by changing the air flow pattern from steady to oscillatory. In the present work, coal flotation with oscillatory air ...

    The froth was generated by introducing air into a preconditioned coal slurry in the cup, and air injection was terminated when the coal froth was believed to be sufficiently high. The vane head was then placed into the froth to perform the measurement. Note that the froth regenerated in the cup is highly unlikely to reproduce the flowing froth in flotation, as bubbles in the froth .
