Bauxite Deposits with Unusually High Concentrations of REE

The laterite profiles attain a thickness of 600 m on slates 300 m on carbonatites and 80 km on kimberlites. The final weathering products are bauxites Al-Ti-Fe laterites and Fe-Mn ochres enriched in REE (up to 50 Ln 2 O 3 and 1 Y 2 O 3 ) Nb (up to 5 Nb 2 O 5 ) Ti (up to 32 TiO 2 ) Th (0.1–0.4 ThO 2 ) as well as Ba P. Zn and V.
