  • Red mud Wikipedia

    Red mud, also known as bauxite residue, is an industrial waste generated during the refinement of bauxite into alumina using the Bayer processIt is composed of various oxide compounds, including the iron oxides which give its red color Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 15 tonnes of red mud are alsoBayer red mud is characterized by its highly oxidizing nature (high Fe 2 O 3 content) and high alkalinity (high Na 2 O content) It can work as an ideal flux and dephosphorizer in the steelmaking process In this study, laboratory experiments on the use of Bayer red mud‐based flux in hot metal dephosphorization and simulated steelmaking processes have been carried out In hot metalApplication of Bayer Red Mud‐Based Flux in the· This paper describes preliminary work to assess the potential for recovering valuable components from Queensland Alumina Limited (QAL) red mud by physical beneficiation Upgrading of Weipa bauxites residue was trialed using a 50 mm hydrocyclone and a Mozley Multigravity Separator (MGS) to recover desilication product (DSP) and TiO 2 fractionsSeparation and Mineralogical Analysis of Bayer Red Mud
