Coal surface control for advanced fine coal .

The primary goal of this project is to develop advanced flotation methods for coal cleaning in order to achieve 90% pyritic sulfur removal at 90% Btu yield, using coal samples procured from six major US coal seams. Concomitantly, the ash content of these coals is to be reduced to 6% or less. Investigation of mechanisms for the control of coal and pyrite surfaces prior to fine coal flotation is ...

The presence, in the flotation concentrates, of the reagents used during the froth flotation process was also investigated using gas chromatography. Pillow-shaped binderless briquettes were produced from coal samples at various moisture contents and a pressure of approximately 17 Mpa using a Komarek B-100A double-roll press.

The Process Of Coal Flotation - dobermannsa

Coal flotation is a separation process performed mainly based on differences in surface hydrophobicity between coal and gangue. The flotation reagent can improve the hydrophobicity of coal, and also the adhesion between coal and air bubbles. Kerosene and light diesel oil are widely used as collectors in coal flotation.
