It is clear trend that flotation performance declines on increasing collector dosage from low level to high level for all three blended frothing molecules.The depression in selectivity is due to coverage of ash particle's surface by collector at higher dosage which results in a decrease in the flotation rate differentials between the low and high ash content particles in the feed coal.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation
