Calcined Bauxite Processing Operation

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. It currently operates three kilns 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.

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.

Calcined Bauxite Processing Plant

Crushing plant: the popular bauxite crushing plant includes jaw crushers, gyratory crushers, cone crushers, roll crushers, impact crushers.

Grinding is the final stage in the comminution process and requires the most energy of all the mineral processing stages. Popular grinding mills applied in bauxite beneficiation application includes ball mill, vertical roller mill, ultrafine mill, trapezium mill, high pressure mill etc.

Separation can be processed by different techniques such as gravity separation, magnetic separation, flotation etc. It aims to concentrate and refine the high grade chrome concentrates.
