What is Froth Flotation? - wisegeek.com

Jun 03, 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 ores.
