WO2016048793A1 - Flotation separation of fine coal,

Coal fines are processed by flotation separation to separate coal particles from ash-forming component particles. Coal fines are mixed water under high shear mixing conditions to form an aqueous slurry of coal fines containing between 15 wt.% and 55 wt.% coal fines. The aqueous slurry is introduced into a coal flotation cell to separate coal particles from ash-forming component particles by,froth flotation carbon from flyash | Solution for ore mining,An important advantage of Caiman froth flotation over other carbon separation techniques is it Fly Ash Separation at RockTron – Pumps, Liquid Ring Vacuum Pumps It enables up to 99% of the fly ash to be recovered Beneficiation Process is an improved “froth flotation the RockTron PFA Beneficiation Process, the carbonUnburned Carbon from Fly Ash for Mercury Adsorption: I,,various components from fly ash, i.e. gravity separation, electrostatic separation, magnetic separation, and froth flotation.
