A ferruginous hydrate of alumina. It is the most commonly used ore for the preparation of aluminum and alumina. It is also used for the lining of furnaces which are exposed to intense heat.
The ore from which aluminium is extracted.
A residual mineral deposit rich in aluminum.
Bauxite - An earthy or oolitic, hydrated aluminum oxide.
A natural aggregate of aluminium bearing materials, more or less impure. Natural hydrated alumina,A12032H2o
Chemical name: Hydrated aluminium Chemical formula: Al2O32H2O See also: Aluminium, Chemical Table.
A mineral. Most of the aluminum in the world can be found in bauxite.
The principal ore of aluminum. A mixture of aluminum oxides and hydroxides that forms from intense chemical weathering of a soil in tropical environments.
An ore or rock composed of hydrous aluminum oxides and aluminum hydroxides. The most economic source of aluminum, it is predominantly found in tropical and sub-tropical regions.
An ore of aluminum, found in richly forested, humid, tropical climate, particularly Nigeria. It is a reddish-brown gemstone. In African cultures it is considered a sacred stone because the color symbolizes the life's force. A.R.T. Precious & Collectible Jewelry
One of the ores from which alumina is extracted and from which aluminum is eventually smelted. Bauxite usually contains at least 45 percent aluminum oxide, and the best grades have a low silica content. About 4 pounds of bauxite is required to produce 1 pound of aluminum.
the raw material mined from the earth we use to make aluminum.
An ore found in soils, often called clays, which contain aluminum metal occurring in combination with other elements, primarily oxygen.
In nature, aluminium is always bound to other elements, above all in the commonly spread silicates and in sparingly soluble hydrated oxides. It is the oxide, first bauxite, that is the source of aluminium production. Bauxite is predominantly found in sub-tropical regions of the world. Bauxite takes its name from \"Les Baux\" in France where it was first discovered.
The main ore from which aluminum is extracted using the Bayer process.
this is the ore that aluminium is made from. Making aluminium from bauxite uses a lot of energy.
A rock composed primarily of hydrous aluminum oxides and formed by intense chemical weathering in tropical areas with good drainage; a major ore of aluminum.
A rock consisting of hydrous aluminum oxide with various impurities; the principal ore of aluminum, and raw material for mullite and high-alumina refractories.
ore from which aluminum is obtained. At one time Jamaica was the world's leading producers of bauxite.
A rock made up of hydrous aluminum oxides; the most common aluminum ore.
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminium hydroxide minerals, plus various mixtures of silica, irontitania, aluminium silicates, and other impurities in minor or trace amounts. Bauxite is a sedimentary rock produced by in situ chemical weathering typically under tropical to subtropical climate conditions.
A clay-like mineral, bauxite is the principal ore of aluminum. It is composed of aluminum oxides and aluminum hydroxides. Bauxite is used as an abrasive, a catalyst, and a refractory for the lining of furnaces which are exposed to intense heat.
a rock, the principal ore of aluminium, consisting mainly of aluminium oxide
An ore from which alumina is extracted and from which aluminum is eventually smelted. Bauxite usually contains at least 45% alumina. About four pounds of bauxite are required to product one pound of aluminum.
An ore of aluminum consisting of moderately pure hydrated alumna, Al2O3× 2H2O.
A reddish-brown gemstone which is actually an ore of aluminum. It is found in tropical climates such as Nigeria. Because of it coloring, some African cultures revere it as a symbol of life's force.
A soil type and ore derived from the weathering of granite (sialic parent rock), and depleted of nearly all soluble elements. Aluminium oxides are virtually all that remain after calcium, potassium, sodium and silicon have been leached out. Bauxite is the principle ore of aluminium, and is predominantly found in tropical and sub-tropical regions.
The primary ore from which aluminum originates. Four pounds of bauxite produces one pound of aluminum.
a rock in which aluminum is found in high concentrations.
Bauxite is an aluminium ore which consists largely of the Al minerals gibbsite Al(OH)3, boehmite and diaspore AlOOH, together with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO2. It was named after the village Les Baux-de-Provence in southern France, where it was first discovered in 1821 by geologist Henri RouvÃ¨re.
