The bulk flotation of oil from Canadian oil sands is an example of separation of a liquid from a solid by a froth flotation process. The removal of nonpolar oils, phenols, fatty acids, mercaptans and other organic chemicals from tank car waste solutions and slurries is an example of the separation of organic liquids from water with solid phase hydrocarbon (coal) acting as the absorbent and ...

Froth Flotation Process Mineral Processing Metallurgy

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.

Flotation an overview | ScienceDirect Topics

Flotation. Flotation is a separation process in which air or gas bubbles are directed at the solid particles and then drive these particles to the liquid surface. Flotation is more beneficial and efficient for removing cells than sedimentation. Flotation can capture particles smaller than 500 μm in diameter (Chen et al., 2011).
