Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles. These shortcomings can be addressed appreciably by ...

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 ...
