2023 bauxite production and reserves (thousands of tons) [1] Country Production Reserves World: 400,000: 30,000,000
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 the main source of the rare metal gallium. [17] During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. [18]
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
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.
Jamaica was the third-leading producer of bauxite and alumina in 1998, producing 12.6 million tons of bauxite, accounting for 10.4% of world production, and 3.46 million tons of alumina, accounting for 7.4% of world production. 8,540 million tons of bauxite was mined in 2012 and 10,200 million tons of bauxite in 2011.

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.
The economy of Guinea is dependent largely on agriculture and other rural activities. [5] Guinea is richly endowed with minerals, possessing an estimated quarter of the world's proven reserves of bauxite, [6] more than 1.8 billion tonnes (2.0 billion short tons) of high-grade iron ore, significant diamond and gold deposits, and undetermined quantities of uranium.
