What is mechanism of froth flotation process

Apr 09, 2021

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

    Mar 15, 2021 Froth flotation of molybdenite is commonly achieved using hydrocarbon oils as the collector. The insoluble hydrocarbon oils adsorb on molybdenite surfaces, resulting in an increase in its surface hydrophobicity and thereby its flotation recovery. However, the underlying mechanism on a microscopic scale was poorly understood. In this study, the effect of
