Abstract:
In one aspect, the present invention is directed to methods for extracting rare earth metals from ores comprising reduction of rare earth metal oxyfluorides. In another aspect, the invention relates to an apparatus for extracting rare earth metals from ores comprising reduction of rare earth metal oxyfluorides. The methods and apparatuses described herein generate rare earth metals from ores with reduced requisite pre-removal of metal oxides found as natural impurities in ores.
