Rare earth element (REE) production is limited in part by inefficient strategies for beneficiation. Hydroxamic acid ligands are promising reagents for the selective flotation of bastnäsite [(Ce,La)FCO 3], a major REE ore mineral, but the mechanism and energetics of adsorption are not understood, interfering with the design of new, more efficient reagents.

Ores are the primary source of obtaining minerals by mineral beneficiation. The process involves several steps depending upon the ore and its composition and properties. Ores are the aggregates of rocks or minerals from which the desired minerals are extracted. They can either contain minerals or metals that are economically important to humans.
