Rare-metal granites as a potential source of critical metals: A geometallurgical case study

Q Dehaine, LO Filippov, HJ Glass, G Rollinson - Ore Geology Reviews, 2019 - Elsevier
Because of their low grades in critical metals such as Light Rare Earth Elements (LREE) or
Sn, rare-metal granites are not considered as economic for metal recovery but, when …
