The packed column flotation technology is commercially proven in processing a variety of coal and mineral fines. It incorporates the packing design to overcome most of the problems encountered by conventional columns or open vessel type cells. The packing elements break up air bubbles through small tortuous passages and support an unlimited froth depth inside the column where nearly all separation takes place. Thus, the packed column is actually a froth separator. The first commercial packed column for coal application was installed at the Pingdingshan Mine, China in 1989. This unit (1.5 m ID {times} 7 m tall) has been used to recover clean coal ({approximately}6% ash) from the black water (10--15% ash) with 82--88% coal yield. The capacity of the unit is 10--12 TPH. Some modifications of the column are being considered to improve product quality and to simplify control strategy.
