Bauxite Wikipedia

Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

Bauxite: The principal ore of aluminum. Geology

Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

What Aluminum Extraction Really Does to the Environment

Nov 09, 2010 Of all the earth’s natural elements, aluminum happens to be the third most abundant resource on our planet in its raw form. With rather humble origins as a soft, red, mineral-laden rock called bauxite, highly valuable aluminum ore contains boehmite, diaspore and gibbsite as well as clay, iron hydroxides and free silica.

Why Should We Recycle Aluminum? thoughtco

Toss an aluminum can into the trash instead of recycling it, and the energy required to replace that discarded resource with new aluminum from bauxite ore is enough to keep a 100-watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours, according to the Container Recycling Institute.

Laterite Wikipedia

Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which produces
