Beneficiation of Bastnaesite Ore with New Flotation

of flotation is to have the desired mineral in solution attach to an air or nitrogen bubble and form a froth layer, which is periodically scraped off and collected. Bastnaesite is a hydrophilic mineral, so collectors are required to make the mineral hydrophobic. The hydrophobic minerals can then attach to the air bubbles and form a froth.
