Bauxite is a residual rock, consisting mainly of a mixture of aluminium hydroxides, whose
industrial significance is primarily due to its profitably exploitable alumina contents. In the …

High concentrations of rare earth elements (REE) are found in the bauxite deposits in the
Songqi area of Henan Province, North China. However, no studies have been carried out on …

The purpose of present work was to provide mineralogical insight into the rare earth element
(REE) phases in bauxite residue to improve REE recovering technologies. Experimental …

More recent data of Greek bauxites from the Parnassos-Ghiona active mines prove that rare
earth elements (REEs) occur mainly in the form of authigenic/diagenetic LREE 3+ carbonate …

In the last few years, many efforts have been devoted to the factors controlling the
distribution of CMs in karst bauxites, residual deposits hosted in carbonate rocks. Most of …

Bauxites in southern France (Provence and Languedoc) have been exploited since the
beginning of the last century. Though most of the deposits are now subeconomic or mined …

Approximately 300 million tonnes of bauxite are processed annually, primarily to extract
alumina, and can contain moderate rare earth element (REE) concentrations, which are …

The Semirom karst type clayey bauxite is located in the Zagros zone, a part of the Irano-
Himalayan belt, and occurs between the Sarvak and Ilam Formations. The Albian to …

The demand for rare earth elements (REEs) has increased over the last decade due to
applications in high technology devices including those in the defense industry. The …

Karst bauxites have recently received renewed attention for their potential as non-
conventional REE sources. Karst bauxites from the Pedernales Peninsula in the Dominican …
