This is a list of countries by bauxite production in 2023. There have been some changes from the geographical rankings of 2022. Data ... 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.
The social and environmental impacts of bauxite extraction are well documented. 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]

The discovery, they say, may be the most significant in a series of archaeological finds made at the mouth of the Miami River in the past 25 years that include the Miami Circle National Historic ...
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.
