202238 The name “bauxite” was proposed by Dufrenoy in 18451 for a material occurring near Les Beaux France that has to consist mainly of a mixture of hydrated aluminumand red iron oxides Hydrated oxides present in the bauxite ore are diaspore and boehmite Al 2 O 3H 2 O Al 2 O 385 Al 45 gibbsite or hydrargillite Al 2 O 33H 2
The present work investigated properties of red ceramic from the Amazonian region after the addition of kaolin and bauxite mixture with 0 10 20 and 30wt in red ceramic industry clay Assessed mechanical properties were flexural strength and Youngs modulus The assessed physical properties were density and porosity
2021113 Mainpat Bauxite is present as cap rock with brownish laterite at the top followed by bauxite then lithomorphs and weathered basalt at the bottom The presence of boehmite was an evidence of intense weathering of kaolin to form bauxite deposit this was conformed after doing full petrography test with transmission Electron Microscopy

201458 The bauxite ore Bayer process materials before precipitation mud residue and sand residue are therefore of radiological interest whereas the alumina product is not8 Positional and personal monitoring data from bauxite mines and alumina refineries in Western Australia have been used to assess the abovebackground annual doses for the
2021123 Bauxite was originally defined by Berthier 1821 as aluminum rich material exposed in the vicinity of Les Baux France At this time the term bauxite identified a mineral with the compositional system Al2O3SiO3H2O Subsequent investigations however have shown bauxite to be more of a rock composition containing varying amounts of hydrated

The mixtures of kaolintalcbauxite which were fired at the range of 1300–1400 °C exhibited dielectric constant values varying between 203 and 28 along with dielectric loss tangent which varied between 01316 and 00002 at room temperature of the laboratory The two mixtures can be considered as promising materials for both ceramic and
2019102 ordinary kaolin And these varieties grade so insensibly into each other that no line of demarkation can be drawn between them The following analyses show the similarity in composi tion between a kaolin and a variety of bauxite which properly speaking is simply a

— Kaolin and bauxite were used as alumina and silica sources to synthesize zeolites hydrothermally The source materials as well as the synthesized zeolites were characterized by Xray diffraction XRD scanning electron microscopy SEM energy dispersive xray analysis EDX and Fourier transformed infrared spectroscopy FTIR
2010101 Bauxite has also been an important target for studies of paleoweathering paleosurfaces and related continental deposits Bárdossy and Coes 1999As the relict of colloidal precipitates resulting from deep chemical weathering of silies bauxite itself experienced an evolution from open strongly oxidized conditions to gradually enclosed
