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.This process entails dissolving the alumina in cryolite a molten solvent An electrical current is run through the mixture causing the carbon from the carbon anode to attach to the oxygen component in the alumina yielding aluminum and carbon dioxide 2 Al2O3 3 C > 4 Al 3 CO2 This process takes place at temperatures between 940 980º C Il

are technically feasible sources of alumina Other raw materials such as alunite anorthosite coal wastes and oil shales offer additionalbauxite rock largely composed of a mixture of hydrous aluminum oxides Bauxite is the principal ore of aluminum Bauxites vary physically according to the origin and geologic history of their deposits some deposits are soft easily crushed and structureless some are hard dense and pisolitic or pealike still others are porous but strong or are stratified or largely pseudomorphic 2022 4 8 Discover profitable strategy access Bauxite export import shipment data
