Bauxite ore Britannica

Bauxite, rock largely composed of a mixture of hydrous aluminum oxides. Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic,

Bauxite My rock family

Bauxite is a sedimentary rock. A sedimentary rock is a rock that is made up of compacted and compressed sediment (dirt, sand, rocks, fossil, debris). After rocks, sand, dirt and other sediment is eroded and weathered through air, wind or waterways, all this sediment begins to pile up layer after layer.

Bauxite: The aluminum mineral bauxite information and pictures

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

Bauxite ALS

Bauxite is the world’s principal source of aluminium and can vary from a very soft earth to a very hard rock. It can occur as red-yellow compacted earth (both friable and re-cemented), small red round pebbles (pisolites), or large pale (pink, white, buff) hard stones (see below left). Physical forms of bauxite Pisolitic Pisolitic Earthy Hard rock

Bauxite Arkansas

The ore also serves as the official state rock which is hard enough to have been used in various types of construction. It was used in 1887 to surface the road from Sweet Home to Little Rock . And in 1893 residents of the next-door-neighbor town of Benton used the then unknown substance to build a home for Dr. Gann in lieu of payment for bills.

Bauxite 101 The Bauxite Index

Bauxite Reserves The top 5 countries, Guinea, Australia, Brazil, Vietnam and Jamaica, hold over 70% of the world’s documented bauxite reserves. Bauxite resources are estimated to be 55 billion to 75 billion tons, in Africa (32%), Oceania (23%), South America and

How Is Bauxite Formed? Reference

Mar 26, 2020· The type of bauxite ore produced is heavily dependant on the region and conditions the ore is created in. Both types depend on heavy weatherization and above average drainage capacity to form. Latertitic bauxite ores are largely formed in tropical regions by the weathering of silicate rocks like granite, gneiss, basalt, syenite and shale being

Bauxite Wikipedia

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

Bauxite an overview ScienceDirect Topics

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3).It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.
