Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Separation of fines by flotation techniques - ScienceDirect

Its selectivity is so great that, for example, cassiterite ores containing 0.2-0.3% Sn are separated by flotation. Flotation, a gravity separation process, is a physicochemical method based on the different hydrophobicity of particles to be separated; hydrophobicity of minerals is rarely natural occurring but may be chemically induced during ...

1 Froth Flotation – Fundamental Principles

Froth flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation. It is currently in use for many diverse applications, with a few examples being:

Froth Flotation Applications - Mineral Processing & Metallurgy

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 ...

History of Flotation Patents - Mineral Processing & Metallurgy

This is the part of the subject of which we have heard the most; indeed, until recently the literature of the flotation process was closely identified with the records of patent litigation.
