DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION ...

In coal flotation, fine bubbles also improve separation as they intensify the difference in the kinetics of the coal from non-coal particles, thus allowing concentrates with lower ash content to be produced without loss in yield. (a) (b) Figure 2: Rate constant as a function of particles size, for three bubble sizes at constant J g of 1.53 cm/s: (a) Silica and (b) Pyrite (from Diaz-Penafiel ...

COAL FLOTATION - Mineral Processing & Metallurgy

29/09/2003· The polymer increased ash rejection in flotation primarily because the coal agglomerates, which were observed in the flotation cell, were smaller and considered to be more selective. For medium and low rank coals, where larger oil concentrations were required, the polymer acted both as an emulsifier and a surface modifier. It was suggested based on the …
