Froth flotationdepends on differences in surface properties betweencoaland shale. Air bubbles are generated within an aqueous suspension of fine rawcoalwith a solids concentration of less than 10%. The hydrophobiccoalparticles attach to the air bubbles and are buoyed to the top of thefroth flotationcell where they are removed asfroth.

Yoon (1982), Yoon and Sabey (1989) studied the effectiveness of salts on theflotationofcoalusing a large number of salts and compared theresultswith those of conventionalflotationwhere kerosene collector and Dowfroth 250 frother were used (shown in Table 8).It was found that theflotationresponses in terms of separation efficiency (defined as combustible recovery-ash recovery) were ...
A laboratory study was conducted to evaluate and compare the effectiveness of nine different frother types when used in a three-phase, continuously operatingfroth flotationsystem. The frothers included several that are commonly used in the industry (e.g., MIBC, 2EH, and F-1) as well as unique frother types (e.g., F-3). The tests were conducted in a 5-cm diameter laboratoryflotationcolumn ...
