Dry Beneficiation of Bauxite Minerals Using Tribo …

The dry low-grade bauxite co-product (tailings) from the separation process would be sold to cement manufacture as an alumina source. Bauxite is commonly added to cement manufacture, and the dry co-product, unlike red mud, does not contain sodium which would prevent its use in cement manufacture. This provides the refinery with a method of ...

Bauxite Residue/Red Mud

Red mud waste residue management has been a continuing issue for review within the alumina refinery operations. With anywhere from 1 to 2.5 tonnes of red mud residue per tonne of Al 2 O 3 produced, the alumina producer must carefully consider the various options available to handle this material. The most common practice 75 years ago was to dump residue slurry directly to …

Bauxite residue (red mud) treatment: Current situation and …

Most alumina plants manage bauxite residue through open-air stacking, which includes wet storage, semi-dry storage, and dry storage methods. Wet storage, with moisture content generally exceeding 70 %, occupies a large area and poses a high risk of dam breaches (Wang and Liu, 2012). In recent years, numerous catastrophic breaches of bauxite ...
