Rare earth elements (REE) become concentrated in the bauxite deposits due to crystallisation of authigenic REE-bearing minerals, accumulation of residual phases and the adsorption of ions on clays and other mineral

It was found that REEs occur in BR in discrete mineral particles. REE-containing particles consist also of titanium (Ti) and iron (Fe), thus they were termed as REE ferrotitanates. REE ferrotitanates were found to form a solid solution between
