Principles Of Froth Flotation With Photos Minerallurgy

Apr 25, 2021 Flotation is better understood and studied when the process is divided into a number of distinct stages or sub-processes. These are described below. The process stages. While all of the stages or sub-processes of flotation occur simultaneously in a flotation cell, they must occur in the correct sequence for any particular mineral particle to float.

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.

Abstract. To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed. Provided these produce sufficiently marked differences of behaviour in the presence of air, they can then be exploited.
