  • Effect of bauxite properties on the settling of red mud

    Dec 01 1996 · Most bauxite deposits are fossil soils in which gibbsite or boehmite are the ore minerals. In the alumina production process with sodium hydroxide (Bayer process) the ore minerals go into solution and the iron-oxide impurities remain insoluble (red mud tailings). The settling behaviour of the tailings is an important economic factor as it
