The amount and quality of concentrate obtained from froth flotation of a coal are very important to determine the efficiency of the separation process. The shape and size of the bubbles in the froth directly affect the amount and purity of the concentrate overflowed during the froth flotation of the coal. The froth structure is significantly dependent on parameters such as the size of the ...

Flotation tests were also conducted with Appalachian coals for comparison;Iowa coals did not respond as well to froth flotation as Appalachian coals. Although Iowa coal floated very slowly and incompletely with only a frother (methyl isobutyl carbinol or MIBC), it floated rapidly when a large dosage of an oily collector (No. 200 LLS fuel oil ...

Flotation is an important part of coal preparation, and the flotation column is widely applied as efficient flotation equipment. This process is complex and affected by many factors, with the froth depth and reagent dosage being two of the most important and frequently manipulated variables.

The C14068 UFT froth flotation test method is a very precise method with very limited operator interpretation. The International Standard ISO 88583 for froth flotation testing of hard coal was only trialled on the Hunter Valley (HV) sample and the results were extremely poor when compared to .

Disclosed is an improved process wherein coal particles are beneficiated by froth flotation under coal froth flotation conditions to separate the desired coal particles from remaining unwanted ash and like gangue material. The improvement of the present invention comprises conducting the froth flotation in the presence of an esteralcohol frothing agent.
