2023 bauxite production and reserves (thousands of tons) [1] Country Production Reserves World: 400,000: 30,000,000
Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.
World bauxite production in 2005 One of the world's largest bauxite mines in Weipa, in northern Queensland, Australia. Australia is the largest producer of bauxite, followed by Guinea and China. [8] Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden.
Australia has been mining bauxite since the early 1960s and is a major economic player in worldwide bauxite mining. It is the largest producer of bauxite in the world, producing 31% of global production in 2016.

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]
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 unit then refines the bauxite into alumina at refineries located in Australia, Brazil, Canada and France.
A major developer in the field of bauxite mining is the Alumina Company of Guinea (ACG-Fria), which is located in Fria; the government of Guinea holds a 49% share while the Reynolds Metals Company holds the 51% balance in this enterprise. [20] Another partner in bauxite mining is Compagnie des Bauxites de Guinée (CBG).
