Uses of Bauxite - Definition, Different Applications

2021-11-29  Bauxite ore is soft and red clay, rich in alumina, and its name originates from Les Baux de Provence, It was a French geologist Pierre Berthier who first discovered bauxite near a village southern France in 1821. Later, a French chemist named Henri Sainte-Claire Deville officially termed the substance as “bauxite” in 1861.

Application of risk assessment to improve sustainability ...

Globally bauxite residue, after removal of the AA, ranges from 0.6–2.3 t/mtA. In this context, the low-risk polygons (high AA, low SR) may not require the washing process. Sending the ore from those polygons to the washing process wastes energy. In addition, the impact of bauxite slurry pumping should be taken into account.
