Froth Flotation Cells - Coal Beneficiation - Parnaby Cyclones

Fine coal can be separated from shale and other waste by the process of froth flotation. The coal is made water repellent by the addition of a reagent such as oil, so that when a suspension of coal is agitated with air it sticks to the air bubbles and floats to the surface, collecting as froth.

Froth flotation - Wikipedia

Coal flotation. The Jameson Cell has been found to be particularly effective in cleaning and recovering fine coal particles. For example, at BHP Coal's Goonyella mine (now part of the BHP Mitsubishi Alliance) eight Cells were installed to replace the entire 32 mechanical cell flotation circuit in 1995 in its 1800 t/h coal flotation plant.

Flotation Technology Advances | Coal Age

 · Column flotation cells are typically arranged in a parallel circuit where each unit receives an equal proportion of feed slurry. The mechanical cells will achieve a higher coal recovery for a given set of operating conditions since the multistage "cell-to-cell" circuity reduces the unwanted short-circuiting of feed to tailings.
