Abstract
Pure alumina is obtained from ferruginous bauxite by heating in a reducing atmosphere to render the iron and titanium magnetic, separating these impurities by magnetic action, dissolving the purified bauxite in hydrochloric or sulphuric acid, digesting to render silica and any remaining titanium insoluble, filtering, and evaporating the filtrate to dryness and calcining the aluminium salt to obtain alumina and recover the acid.
