The first commercial alumina production from bauxite ore was done by soda sintering process developed by Louis Le Chatelier in 1855. In this process, bauxite ore is sintered with soda ash (Na 2 CO 3) at about 1200 °C to form NaAlO 2. The sintered mass is subsequently leached in an aqueous medium to dissolve NaAlO 2. The residue is then ...
