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 …

In the present work, a combination of various techniques is utilized for the study of nano-
mineralogy and-geochemistry of high-grade karst-type bauxite (Al-rich and Fe-depleted …

The present research work is focused on the development of an alternative microwave
reductive roasting process of red mud using lignite (30.15 wt.% C fix), followed by wet …

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 …

Niobium (Nb) is one of the most immobile elements during supergene weathering, widely
used for mass-balance calculations, despite elusive information on the mechanisms …

Karst bauxite deposits are currently investigated as a new resource for rare earth elements
(REE) in order to avoid present and future supply shortfalls of these critical metals. The …

The pyrophyllite-rich ferruginous (PRF) bauxites in northwestern Iran from the Irano–
Himalayan karst belt are deposited on the paleokarst of the middle Permian carbonate …

Bauxite residue (BR) is a valuable polymetallic resource, but its utilization is hindered by
challenges such as high alkalinity, fine particle size, and complex mineral composition …

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 …
