Bauxite Residue Management

b. Production of bauxite residue The amount of bauxite residue produced by an alumina plant or refinery is primarily dependent on the sources of the bauxite and secondarily on the extraction conditions used by the plant. In the extreme, this can vary from 0.3 to as high as 2.5 tonnes of residue per tonne of alumina produced, though typically

Iron-rich encrustation on the footwall of the Gánt bauxite ...

Investigation of the iron-rich encrustation under the Gánt bauxite in the Vértes Hills (Hungary) provides good evidence for preservation of organic matter. The organic matter probably was trapped during rapid redeposition of bauxitic material by episodic mudflow/debris flow onto a karstic surface, triggered by synsedimentary tectonism associated with Early to Middle Eocene strike-slip motions.
