Common Bauxite Mineralogy Data

Minerals | Free Full-Text | Geochemistry and

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 present work focuses on the geochemistry and mineralogy of the REE in karst bauxite deposits of the Catalan Coastal Range (CCR), NE-Spain. It is revealed that the studied bauxitic ores have a dominant breccia and

Bauxite - minerals

Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of

data to map the limestone and bauxite deposits in southern India by using spectral unmixing methods. Amin and Mazlan (2011) have used ASTER data to map the muscovite, kaolinite, alunite, epidote, calcite and chlorite minerals. Guha et al. (2013) have used ASTER data to map the laterite bauxite deposits in the state of Jharkhand in India.

In this study, the mineralogical and chemical compositions of bauxite from San Giovanni Rotondo (SGR) on the Gargano Promontory (northern Apulia, Italy) are presented and discussed with the aim of assessing the nature of its source material. Bauxite from the SGR, which is known as the "Montecatini mine", was exploited intensively until the 1970s to recover alumina.

CHEMICAL-MINERАLOGICAL CHARACTERIZATION OF BAUXITES

parameters, these bauxites have good quality with high silicon module and high content of aluminium oxide. The loss of ignition is known to depend on the mineralogical composition of bauxite. With the bauxites investigated this value ranges from 8.89 to 28.20% which indicates that they have different mineralogical compositions.
