Bauxite takes many physical forms including small red peas, redyellow "soils", and large, pale, hard stones. How to define an orebody. The main criterion for identification of an ore body as bauxite is that it should contain aluminium in the form of aluminium hydroxides, the minimum content being about 30%(measured as Al2O3). Bauxite alumina

Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery. However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a
The production of aluminum metal from bauxite requires huge amounts of energy much of it electrical while converting bauxite ore to metal, and when reclaiming minedout lands. Aluminum metal can be produced much more efficiently (and economically) from salvaged aluminum, scrap because it requires only 5% as much energy to do so.
What is Bauxite? Bauxite is not a mineral. It is a rock formed from a laterite soil that has been severely leached of silica and other soluble materials in a wet tropical or subtropical climate. It is the primary ore of aluminum. Almost all of the aluminum that has ever been produced has been extracted from bauxite.
3. A g sample of bauxite (the primary ore of aluminum) was analyzed for aluminum. The sample was pulverized and dissolved in concentrated nitric acid. The HNO3 was removed by evaporation and solids dissolved in hot water with a very small quantity of nitric acid added. Insoluble solids were removed by filtration and discarded.
