Rare metals granites have always been considered of poor economic value due to their low metal grades but, when altered, they are often exploited for their industrial minerals. This work address the recovery of critical metals (CRMs) including Light Rare Earth Elements (LREE) and rare metals (Sn, Nb, W) from St Austell (UK) kaolin residues though the development of a beneficiation process. Results shows that CRMs are pre-concentrated in the micaceous residue stream with LREE grades of 170 ppm, which account from 40% to 60% of the mass of CRM entering the plant. Analysis of this residue streams shows a high variability of CRM grades and suggest a cut-off grades for some of them. A combined gravity/flotation process have been developed for th...
