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.

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.
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.

Found around the world in tropical climates, big African pompano catches have surged in recent years in the Gulf, and angler Dave Miller might have led one of his friends to a recent world record.
Bauxite is only 40-60% aluminum oxide. [8] The elements that make up the rest of bauxite are also very useful. [9] Globally, 68 million tons of aluminum were mined in 2021. This aluminum is mostly used in vehicle production, construction, and packaging like cans and foil. The two largest bauxite producers are China and Australia. [8]
