Latest Patents

One of her latest patents is titled "Recovery of alumina from bauxite." This Bayer alumina recovery process involves the addition of lime at an intermediate or final wash stage of the red mud recovery circuit. This innovation enhances flocculation, particularly with flocculants that have lower anionic content. The process is especially beneficial for liquors containing high amounts of sodium carbonate and for situations where the mud is settled by mud stacking. Another significant patent is "Recovery of alumina trihydrate in the Bayer process." In this process, alumina trihydrate crystals are formed in the pregnant liquor and are flocculated using a combination of dextran and synthetic polymer, typically a homo- or copolymer of acrylic acid. This method is particularly advantageous when the liquor contains organic components such as humate and/or oxalate.
