Monazite is a major rare earth elements (REE)bearing phosphate mineral predominantly found in association with hematite and quartz in some Australian rare earth deposits. The flotation of rare earth oxides (REO) in monazite from mixtures containing monazite, hematite, and quartz with hydroxamic acid as a collector has been investigated using an IMN microflotation cell and a L Denver flotation cell.

Different flotation reagents had been tested. Only a rare earth concentrate with grade 15%~20% and the low recovery could be gotten by using fatty acids, such as oxidized paraffin and oleic acid, as the collector in rare earth mineral processing in earliest. C5 ~ 9 hydroxamic

Affinities of these two resins for pairs of REE adjacent to each other on the periodic table were evaluated in batch tests with a separatory funnel and mechanical wrist shaker. Each resin was saturated with the rareearth ion pairs from chloride or nitrate solutions containing equimolar concentrations of the two adjacent elements.

Still have a kind of mineral intergrowth combined process, is a rare earth oxide ore containing 7% ~ 10%, with hot bubble flotation, get concentrate containing 60% rare earth oxides. Use 10% hydrochloric acid leaching, removing the concentrate of calcite carbonate minerals, such as the concentration of rare earth oxides grade rose to 70%.

But the crucial element in escaping China's rareearth rule isn't new mines, it's rebuilding the expertise and infrastructure to process the finicky metals, experts say. Price war
