Bauxite Is An Ore Where Is Enriched Through In

bauxite - cargo handbook - the world's largest cargo,it is also known as aluminium ore and usually obtained from open cast mines. bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. approximately 70% to 80% of the world's dry bauxite production is processed first into alumina, and then into aluminium by electrolysis as of 2010..mining and refining – process,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..
