US Patent Application for FLOTATION SEPARATION OF FINE

US Patent Application for FLOTATION SEPARATION OF FINE

Sep 24 2014 · 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

air sparge systems for solids flotation

To achieve separation an air sparging device is required to produce bubbles in the flotation cell. In column flotation operations sparging devices generate small bubbles into the cell to carry the desired mineral to the surface for later recovery and processing. However field studies suggest that air injector systems are not always optimized.
