Aluminium is part of many, very common rock-forming minerals. For example, feldspar, a family of very common igneous mineral, contains aluminium in its formula: (K,Na,Ca) Al2 Si2 O8. Up to 35% of granite is made up of feldspar minerals. In fact, a...

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 ...

mal analysis methods. Chemical and structural characterization is complemented by the re-sults of scanning electron microscopy with EDX analysis. The information obtained was used for the assessment of the quality of investigated bauxites from the aspect of their ap-plication in the production of alumina.

Bauxite. Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH)3), boehmite (-AlO(OH)) and diaspore (-AlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).. In 1821 the French geologist Pierre Berthier discovered bauxite near

Chemical Formula: Al 2 O(OH) 4 Pisolitic or earthy and granular rock which is essentially a mixture of hydrated aluminum oxides, generally with impurities. Colors: Dirty-white when pure, but usually found as yellow, gray, red or brown in color. Hardness: ranges 1 to 3 Hardness depends much on impurities and porosity of the rock.

The lower concentration of organic matter in karstic bauxites suggests pure kaolinite due to low concentration of organic matter. These are generally found in regions of hot, humid tropical and subtropical climates. Bauxite Formula. In its raw form, the main bauxite chemical formula is Al2O3.nH2O, and it contains following minerals:

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small ...

All lateritic bauxites contain a finite amount of organic carbon compounds, a proportion of which are solubilised in the digestion process. This causes a build-up of organic compounds in the recirculating process liquor to concentrations determined by a complex interaction of inputs, outputs and reactions in a dynamic steady-state.
