Bauxite Mining Process List

Alcoa has ownership in seven active bauxite mines globally and operates four of them, making us among the largest bauxite producers in the world. We have access to large bauxite deposits with mining rights that extend in most cases more than 20 years. Our global network is strategically located near key Atlantic and Pacific markets.

Bauxite is the only ore containing 20 25 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.
