Collector Chemistry for Bastnaesite Flotation – Recent Developments.

One of the most important aspects in any flotation separation is the choice of the flotation collector. For this reason, based on both our recent research developments and the results from other researchers, this detailed review focuses on fundamental surface chemistry features of fatty acid, hydroxamate, phosphonate, and phosphate as collectors for the flotation recovery of the rare earth (RE) mineral, bastnaesite, including selectivity considerations with respect to separation from calcite, barite, and quartz.
