Apr 06, 2020 Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.

Disclosed is an improved froth flotation process wherein preselected solid particles are selectively separated under froth flotation conditions as a froth phase from remaining solid feed particles as an aqueous phase in the presence of a collector amine. Such improvement comprises conducting said froth flotation in the presence of an effective proportion of an amine oxide promoter.

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.
