  • explain leaching of alumina from bauxite - Brainly

    In the extraction of aluminium, the significance of leaching is to concentrate pure alumina(AL2O3) from bauxite ore. Bauxite usually contains silica, iron oxide, and titanium oxide as impurities. In the process of leaching, alumina is concentrated by digesting the powdered ore with a concentrated solution of NaOH at 473-523K and 35-36 bar.
