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.
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.
Rio Tinto Alcan is the world's leading producer of bauxite (shown here with a US cent for scale). Rio Tinto divides its Aluminium operations into three main areas—bauxite, alumina and primary metal. The Bauxite and Alumina unit mines raw bauxite from locations in Australia, Brazil and Africa.
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.

The Weipa bauxite mine is a bauxite mine at Weipa on the western Cape York Peninsula in Far North Queensland, Australia. A geologist named Harry Evans discovered the vast bauxite resource in 1955. [1] Operations commenced in 1963. The mine is owned by Rio Tinto. Power to the mine is supplied via a 6.7MW solar photovoltaic solar farm on site. [1]
The history of bauxite mining in Ghana dates back to the early 20th century.Bauxite was first discovered in the country in 1921 at Awaso, in the Western North Region.The first operations began in the 1940s, with the Ghana Bauxite Company (GBC) managing the extraction and export of bauxite since then.
