We can get aluminum from bauxite beneficiation process, and the elements of residues in the process are iron oxide (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%), and insoluble oxidation aluminum (0-20%).. These elements are difficult to completely eradicate from the residue, so it has caused a series of ecological problems.

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al (OH) 3 ). It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.
Aluminum (Al) Ore. Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth's crust, comprising about 8% by weight.
On July 3, 1952, the Alcoa Mining Company shipped its last trainload (2,600 tons) of bauxite ore out of Arkansas using the Bauxite and Northern Railroad. It was reported that all future ore mined there would be shipped by the Aluminum Ore Company from its newly completed $54 million plant at Bauxite.
The town that bauxite built. First discovered in the state in the late 1880s, bauxite ore played an important role in Saline County and for the world. For a while, the town of Bauxite, which even took its name from this rock, produced most of the world's aluminum. You can learn more about this history at the Bauxite Historical Association ...
It is a type of lithified soil which is relatively low in silica and high in aluminum. Bauxite was discovered in Arkansas before 1900 and was a major source of ore for aluminum metal for some 90 years in Saline and Pulaski Counties. There are many uses for processed bauxite, aside from metal, including abrasives, cement, refractories, and ...
