  • What Are Bauxite Tailings Or Red Mud?

    Bauxite tailings are produced during the Bayer Process which is the most commonly used method of refining bauxite to aluminum oxide. Estimates indicated that roughly 95% of the aluminum oxide produced in the world was made through the Bayer Process. After the bauxite ore is extracted from mines, it is taken to a plant where it is refined.

  • Mining and Refining – Bauxite Residue Management

    The pH level of the residue is generally up to 13 or higher in some cases, due to the presence of alkaline sodium compounds, such as sodium carbonate and sodium hydroxide. Like most ores and soils, bauxite can contain trace quantities of metals such as arsenic, beryllium, cadmium, chromium, lead, manganese, mercury, nickel and naturally-occurring radioactive materials, such as thorium and uranium.

  • Red mud (bauxite residue) – an unnecessary problem?

    Bauxite residue is strongly alkali (high pH values) because it contains high concentrations of lye (NaOH). This is why it cannot simply be discharged into the natural environment. In itself, NaOH is not so difficult to deal with and can be neutralised using substances such as hydrochloric acid (HCl) to produce clean water and table salt.
