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.

Introduction to Mineral Processing - cpchem

The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

Flotation Process - scientific

Abstract: According to the properties of a medium-and-low grade collophanite, a contrast testing study was conducted on the basis of three kinds of flotation process. The result suggests that it is difficult to obtain high-quality phosphate concentrate from removing carbonate minerals only by the use of reverse flotation process.
