    Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240°C the

  • INTERNATIONAL ALUMINIUM INSTITUTE FOURTH SUSTAINABLE

    Unlike other base metal ores, bauxite does not require complex processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay. In many types of bauxite, clay is removed by some combination of washing, wet screening, cycloning and sorting.

  • Guinea’s bauxite mining development CRU

    Third-party bauxite demand occurs when a refinery purchases either a proportion or its entire bauxite requirements from a mine that is not owned by the refinery. That is, the refinery is not associated with the bauxite mine, and thus the buyer and seller are non-related parties. We also recognise that some transactions may be better classified as tied or related party transactions. In this grouping, we include

    Mined bauxite ore is refined into alumina, through what is known as the Bayer process. The Bayer process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process. A white powder, similar to table salt, called alumina is produced and can then be smelted into aluminium metal to be used in things like cars, packaging, powering the
