Annual production of bauxite in the United States, 1900-2013. Bauxite mining in the United States produced an estimated 128,000 metric tonnes of bauxite in 2013. [1] Although the United States was an important source of bauxite in the early 20th century, it now supplies less than one percent of world bauxite production.
Most of the world's bauxite deposits can be found within 1 to 20 metres (3 ft 3 in to 65 ft 7 in) of the earths surface. [21] [22] Strip mining is the most common technique used for extracting shallow bauxite. [22] This process involves removing the vegetation, top soil, and overburden to expose the bauxite ore. [22]

Rio Tinto's main business is the production of raw materials including copper, iron ore, bauxite, diamonds, uranium and industrial minerals including titanium dioxide, salt, gypsum and borates. Rio Tinto also performs processing on some of these materials, with plants dedicated to processing bauxite into alumina and aluminium, and smelting iron ...
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. [1]
Bauxite is a raw material used primarily in the production of aluminium. The bauxite ore is refined into alumina before being smelted into aluminium. [3] Australia is known for its high-grade ore, especially in the Weipa and Gove deposits. [2] The quality of bauxite ore is determined by its available alumina (Al 2 O 3) content.
