Froth Flotation Handbook
Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen.

Beneficiation of Fine Coal: Froth Flotation Efficiency
The process was not used in the Witbank/Middelburg area since the coal from this region was generally considered "non-floating". When spirals were introduced in the early 1980s, the fine coal that would normally have been subjected to froth flotation was sent to the more economical spirals at plants such as Grootegeluk.

Coal flotation as a rate process | Mining, Metallurgy
Coal flotation is found to follow a first order process with the coal floating much faster than either pyrite or ash. This circumstance may be used to achieve gangue rejection during flotation. When floated with MIBC, cresol, or pine oil frothers, coal floats in the size sequence: 208 µm (−65 mesh), 589 × 208 µm (28 × 65 mesh), and 1.17 ...

Recovering Gold through the Froth Flotation Process
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.
