Product Description

Non Calcined Bauxite Exporter

Details:

We have well established and modern infrastructure which assist us to manufacture and supply of Bauxite.

Bauxite is a mixture of the minerals gibbsite (Al2O3 - 3H2O) boehmite (alpha monohydrate, Al2O3 H2O) and Diaspora (beta monohydrate, Al2O3 H2O). It is a unique mineral in the sense that, by and large, this is the only mineral from which aluminum is extracted economically. Beside aluminum its other important uses are in the manufacture of refractories, abrasive and chemicals. Low-grade bauxite finds use in cement industry. Among minor uses mention may be made of its use as a fluxing material in steel melting shop and in ferro-alloy industries in place of fluorspar and as absorbent in the refining of kerosene.

The Bureau of Indian Standards (BIS) has prescribed the following specification of bauxite for metallurgical uses.
