Processing of REE enriched apatite deposits has previously been explored by Soltani et al., [49] and Harbi et al., [67]. The processing of britholite, the end member of the REE 3+ and Si 4+ substitution in apatite, has previously been investigated by Yang et al., [68]. Britholite was only a secondary ore mineral to elphidite in the deposit with ...Web
