3.3 Flotation. Coal flotation is the most proficient technique used to improve the nature of fine particles by diminishing pollution substance (Majumder and Barnwal, 2011).The hypothesis of froth flotation is complex and has not been fully comprehended. This reality has been brought by many difficulties observed in coal preparation plants (Ye et al., 2017).

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

The first patent for froth flotation was granted in 1905 to the Elmore brothers, Francis Edward and Alexander, who used a mixture of oil and air to separate sulphide ores. By the 1920s, froth flotation had become the dominant mineral separation method as larger and more efficient cells replaced earlier gravity-based jigs and shaking tables.

This would be reflected in froth color and bubble size. Both are dependent upon the mineral that is being collected. If however there is too much of the modifying agent being used then the froth MAY or MAY NOT reflect this in color as well. The reagent being used and the mineral being collected will dictate the characteristics of the indication.
