CALCINE BAUXITE. Calcined Bauxite is obtained by calcining (heating in a Rotary Kiln) superior grade Bauxite at high temperatures. Further, this process removes the moisture leading to a higher alumina content. Meanwhile, compared to an alumina content of about 56 % to 57 % in raw Bauxite, Calcined Bauxite has an alumina content of 72 % to 90 %.

Refractory Grade Bauxite
After crushing and screening to remove fines, and in some instances washing to physically remove clay and silica contaminants, the green or raw bauxite is usually fired at temperatures in the range of 1,400° C to 1,800° C in order to transform the material into corundum and mullite.

CALCINED BAUXITE
CALCINED BAUXITE 1. INTRODUCTION: India currently imports 60% of its Calcined Bauxite from China. Spurred by expansion of domestic steel production, a scarcity of acceptable quality of bauxite from China and raising import cost, drives are now under way in India to produce high grade bauxite from domestic bauxite sources.

Product
Bauxite is heated at around 1500°C in modern rotary kilns, to remove water and produce Calcined Bauxite. This results in a much harder product, comprised mostly of Alumina (also referred to as Aluminium Oxide), which in crystalline form is known as Corundum.

Effect of chemical composition of calcined bauxite aggregates
The mineral compositions of calcined bauxite aggregate are mullite and corundum. SiO 2 is mainly found in mullite, and the Moh’s hardness of mullite only is 6. While, the Moh’s hardness of corundum is 9. Calcined bauxite aggregates with the higher contents of Al 2 O 3 show better polish resistance, namely higher PSV value.

Uses of Bauxite | Bauxite Formula & Principal
For industrial purposes, calcined bauxite is used as an abrasive. Sintered bauxite (Calcined bauxite) after crushing and heating at a very high temperature is used for making fine sand-blasting abrasive beads in equipment where friction must be developed to smoothen a rough surface or roughen a smooth surface.

Bauxite residues are then removed, leaving the process liquid, termed “green liquor.” The reaction is then driven back in the opposite direction during precipitation, to produce crystals of aluminum trihydrate, which are then calcined to produce anhydrous aluminum oxide (alumina).
