Abstract Natural fluorite is used for growing CaF 2 boules from melt by an improved technique Chemical treatment of the starting ore decomposes the accessory minerals, thus producing small amounts of the oxides of Si, Al, and Fe insoluble in the melt, whereas the overall content of rare earth elements (REEs) of hundreds of μg g −1, remains unchanged.
