Bauxite (Gibbsite, Boehmite And Diaspore)

We are exporter of Bauxite.

Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH)

Bauxite is used in a lot of industries like the chemical industry, refractory, abrasive, cement, steel, and petrol industry amongst others. In chemical, bauxite along with alumina is used in the manufacturing of aluminium chemicals. In refractory, it is used as a raw material for making several products.

Raw Bauxite:

Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH). We are a major Raw Bauxite Exporter based in Maharashtra (India) and catering to the diverse demands of several middle and eastern Asian countries.

About Raw Bauxite:
The processing of Raw Bauxite is done at a number of alumina refineries in the world. Bauxite can be processed at a low-temperature autoclave digestion (145 oC to 155 oC). Raw Bauxite can be used also for sweetening stage and for non-autoclave digestion in agitators (105 oC).

About 85% of bauxite mined worldwide is used to produce alumina for refining into Aluminium metal and the balance 15% is processed and value added to make its way to other uses like refractory, chemical, cement, abrasives, etc. Aluminium is possibly the most versatile product with applications in almost every industry. Since Bauxite is the primary source for Aluminium there will always be an ongoing promising demand for the same.

Application & Uses of Bauxite:
Raw Bauxite is successfully used for metallurgical grade alumina production besides applications in the cement industry, alumina chemical, steel, alum, energy industries, flame-retardants, etc. Bauxite is used in :
- Aluminium
- Cement
- Chemical
- Blast Furnaces
- Iron/Steel Ladles, etc.

Advantages of Artha Bauxite:
Artha Mineral Resources has good sources for Gibbsitic Bauxite which requires low digestion temperature (145 oC -155 oC) making it more economical to process. Mines are also in close proximity to all-weather ports which makes it very convenient and cost effective to ship this material.

Features Of Bauxite Ore

Bauxite, an aluminium ore, is the world’s main source of aluminium. It consists mostly of the minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite.

Applications
Abrasives
Refractories

Bauxite, rock largely composed of a mixture of hydrous aluminium oxides. Bauxite is the principal ore of aluminium. bauxite. Related Topics: ore laterite gibbsite boehmite diaspore. Gibbsite (alumina trihydrate), boehmite, and diaspore (alumina monohydrates) are the main ore minerals. Bauxite is a high-aluminum-content rock.

The composition of bauxite consists mainly of aluminium hydroxide minerals, such as gibbsite Al(OH)3 along with various impurities such as iron oxides, silica, and titanium. The colour of bauxite can range from grey to brown, yellowish-brown, or reddish-brown, depending on the presence of impurities. Bauxite is a crucial raw material for the production of aluminium, which is widely used in various industries such as transportation, construction, packaging, electrical appliances, and aerospace. Aluminium is valued for its lightweight, corrosion resistance, high conductivity, and recyclability. Bauxite mining and aluminium production have significant economic impacts in countries with abundant reserves.

In its mineral form Bauxite, Aluminium is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminium oxides (gibbsite, boehmite or diaspore), which are often expressed as Al2O3xH2O but are more commonly regarded as impure Al2O3. Bauxite is claylike and earthy, and ranges in colour from white to deep brown or red according to the nature and quantity of its components. The major impurities in Bauxite are iron oxides (goethite & hematite), silicon dioxide, the clay mineral kaolinite as well as small amounts of anatase (TiO2). Consequently, its composition varies considerably with alumina constituting from about 50% to about 70%. Aluminium content can be accurately and precisely determined over a broad analytical range simultaneously along with Si, Fe, Mn, Ti, Zr and up to 20+ other elements.
