    Collectors are commonly hydrocarbon liquids such as diesel fuel or fuel oil. In the United States, flotation is typically performed on only the finest fractions of coal ( 0.1 mm), although coarse particle flotation ( 0.6 mm) is practiced in Australia where coal floatability is high and the contaminants in the process feed low

    Jan 01, 2006 In general, flotation agents are classified according to their purpose as collectors, frothers, depressants, modifiers and flocculants. Structure of those molecules consists of polar and/or non-polar portions as shown in Fig. 5.1.Non-polar portion, which may be linear, branch or ring hydrocarbon, interacts very weakly with water molecules and therefore is termed hydrophobic group
