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.

1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Scale-up in froth otation: A state-of-the-art review

2019-9-5  Froth otation was patented in 1905 for the concentra-tion of ores (Sulman et al., 1905). It is now the most im-portant mineral processing method in the mining industry, because of its technical versatility and cost-e ectiveness (Wills Finch, 2016). Flotation is also used in other industries, such as oil sands concentration (Rao Liu, 2013), ionic

Celanese - The chemistry inside innovation

Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water, and air bubbles.
