Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. The climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.
Compared to gold, silver, lead and copper — metals that people have extracted, refined and used for millennia — aluminum is a relative newcomer. ... an abundant aluminum ore — bauxite — and a process of refining this ore using electricity. The discovery of bauxite occurred near Les Baux, France, an ancient village near the Mediterranean ...
The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is one of the world's largest producers of bauxite, with five …
The sequence characteristics of the bauxite ore body reflected that the ancient oxidation–reduction conditions had varied between the concave and convex Ordovician limestone top interfaces. It was found that due to controlled conditions of the paleo-karst topography of the bases, the formation characteristics of the bauxite ore bodies were ...

For a bauxite ore to be economically processed it typically contains 30-50% of extractable (termed available) alumina, up to 20% of iron oxides and 2-5% of silica ...
Physical Properties of Bauxite. Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale.It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
Iron ore: Brazil is a world leader in iron ore production, ranking #2 in global exports. This ore is a key ingredient in steel manufacturing. Bauxite: Used primarily to produce aluminum, Brazil ranks #3 in bauxite exports worldwide. Gold: While not as predominant as iron ore or bauxite, gold is still a significant mineral resource in Brazil ...
Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic, or …

Aluminum processing - Ores, Refining, Alloying: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
While the production of bauxite and chromite fell in 2017-18, the output of other minerals such as iron ore, gold, copper and manganese increased, according to estimates of the Ministry of Mines.
