Flotation Oils for Froth Flotation ArrMaz

Froth flotation is a common process for the separation of liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals. Once at the surface, the select minerals are supported by a froth layer until they are

What is Froth Flotation?

Nov 07, 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.
