  • Method of digesting bauxite via the Bayer process with the addition of reducing agents
    Patent number: 4059672
    Abstract: The settling rate of caustic alkali-digested goethite-containing bauxite or laterite, or the like, is increased by carrying out the digestion in the presence of a reducing agent capable of reducing the trivalent iron component of the goethite to a lower valence so as to convert the goethite to hematite, magnetite, metallic iron, or combinations thereof, which enhance the settling rate of the digestion mass.
