16.03.2017Oxidized coal is difficult to float with common oily collectors because oxidation processes occurring on the coal surface reduces the surface hydrophobicity of coal. Grinding pretreatment has been widely applied in the improvement in the floatability of oxidized coal. However, there is no sufficient investigation into the optimization of grinding conditions for the

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery. Meanwhile, increasing the collector dosage
