What is Bauxite?

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.

Australian Bauxite | The Australian Aluminium Council

Australia is the world''s largest producer of bauxite. In 2020, Australian bauxite production was 102 million tonnes (Mt). 37 Mt of bauxite was exported, and the remainder converted to Australian alumina. The major Australian bauxite mines are: Boddington (Western Australia) – South32. Gove (Northern Territory) – Rio Tinto Aluminium.
