Bauxite residue is the waste generated during alumina production by Bayer's process. The amount of bauxite residue (40–50 wt%) generated depends on the quality of bauxite ore used for the processing. High alkalinity and high caustic content in bauxite residue causes environmental risk for fertile soil and ground water contamination. The caustic (NaOH) content in bauxite residue leads to ...

21 To effectively refrain rocketing rise of domestic alumina capacity To use as much oversea bauxite as possible, but this has been limited increasingly. For example, bauxite exporting is restricted in Indonesia and so on. To develop the effective alumina production process from low grade bauxite in order to reduce the energy consumption and the
Abstract: Lowgrade diasporic bauxite was treated with hydrocyclone of small coneangle. The effects of apex diameter, feed pressure and feed concentration on separation indexes were tested, and then the separation process was discussed by hydrokinetics tentatively.

Jan 07, 2018Impurities are very important to consider when identifying an economic bauxite deposit, as bauxite with higher impurity content typically attracts a discount to market prices due to a greater cost on the refinery to remove and manage the waste.
A new environmentally friendly design for lowgrade diasporicbauxite processing which is different from the Bayer and sintering processes was proposed in this paper. In the redesign of alumina production technology, a mixture of bauxite ore and sodium hydroxide solution was heated at a higher temperature.
