  • Leaching Kinetics of Bauxite in Hydrochloric Acid: Mineral

    The Bayer process is currently used to produce cell-grade alumina from bauxite. However, if the reactive silica content in the bauxite exceeds 7%, losses of caustic and aluminium as sodalite (2 Na 2 0.2 Al 2 O 3 ·3 SiO 2 ·2 H 2 O) become economically unacceptable. As Australia possesses large tonnages of bauxite containing more than 7% reactive silica, a process for the production of cell
