What is Bauxite? - Mineral, Formula, Uses with Videos and FAQs
Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.

Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.

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 mined-out 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.
