  • What is Froth Flotation?

    Mar 04, 2020· 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.
