As part of Ashapura’s commitment to move up the value chain with value added products, a few years ago the Company successfully started producing Calcined Bauxite.

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 °C to 1600 °C). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 84 % to 88 %. The heating is carried out in rotary kilns. Ashapura currently operates three kilns (capacity 90,000 TPA) at its state-of-the-art plant in Jamnagar, Gujarat. Calcination is done at different temperatures ranging from 850 °C to 1600 °C depending upon the customer’s requirement.

We produce Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We have 3500 acres of mining area where we perform captive mining. Hence, are committed to provide consistency in quality and availability of product at extremely competitive prices.

Currently Ashapura is supplying to reputed refractory producers in India along with export to various countries across the world.

Applications of Calcined Bauxite

	Refractory Grade Calcined Bauxite (General Grade and Low Ferric Grade) To make refractory grade, Bauxite is thermally treated at 1600 °C to produce Calcined Bauxite where the Alumina content is mostly above 84%.
	BFA Grade, Proppant Grade and Road Surfcaing Grade To make the above grades, Bauxite is thermally treated at 1000 °C – 1200 °C to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.
