Flotation behavior of hard-to-separate and high-ash fine coal · PDF file

flotation difference between particles is either minimal or fine slimes content in coal samples is high, conventional froth flotation methods mainly suffer from lack of selectivity for fast-floating coals because of flotation of middlings and entrainment of fines in the froth (Polat et al., 2003).

Jameson cell - 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.

Column Flotation of Fine Coal

Flotation samples were prepared by grinding finely pulverized (-65 mesh) samples of precleaned Pittsburgh No. 8 seam coal for 4 minutes in a stirred ball mill. This procedure produced a mean particle size of =10 µm. The samples were diluted to a desired solids content and reagents added as specified by the experimental design.

The coal industry wants to improve combustible recovery, reduce beneficiation unit costs, and attain efficiency optimization, especially for fines and ultrafines. A key beneficiation method for fine and ultrafine coals is froth flotation, where frothing reagent is used to generate and stabilize air bubbles that capture and carry hydrophobic particles. Use of frothing reagent constitutes the ...

Fine Coal Flotation: A Mineral Processing Problem - AusIMM

For some time fine coal (-0.5 mm) flot ation has been considered as a bulk flotation problem. Combinations of hydrocarbon oils and frothers have been used as surface active agents in coal flotation. The selectivity of the flotation process has always been poor in such cases. With the increase in fine coal production due to mining methods and coal handling systems, optimisation of fine coal ...
