What is Froth Flotation? - wisegeek

Feb 05, 2019 · Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated oresSeparation and recovery of thermoplastics by froth floatation,@article{osti_750553, title = {Separation and recovery of thermoplastics by froth floatation}, author = {Karvelas, D E and Jody, B J and Pomykala, J, Jr and Daniels, E J}, abstractNote = {This paper describes efforts by Argonne National Laboratory to develop a froth flotation process for separating and recovering plastics from mixed 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
