It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. Bauxite appears dull in luster and is reddish-brown, white, or tan in color. In 1821 the French geologist Pierre Berthier discovered bauxiteRed mud - Wikipedia,Red mud, preferably known as bauxite residue, is an industrial waste generated during the processing of bauxite into alumina using the Bayer process. It is composed of various oxide compounds, including the iron oxides which give its red colour. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 1.5 tonnes of red mud are also

Bauxite mining in the United States - Wikipedia

Bauxite deposits occur in beds of kaolinite clay in the Nanafalia formation of the Wilcox group, of Eocene age. Mining of bauxite and kaolinite is currently being done by Mullite Company of America (Mulcoa). Spottswood, Virginia. Bauxite was mined at two mines near Spottswood, Virginia, from 1940 to 1946. Total production was about 30,000 long tons, from deposits associated with limestone.Bauxite Ore Extraction Process - Grinder Process,Generally speaking bauxite is found between 1 to 5 metres in depth and is shown in the image adjacent.Bauxite ore ranges in character from solid hard cap or duricrust, to friable fragmental or nodular material, to unconsolidated finely nodular pisilotic gravel. The bauxite gravel is typically composed of rounded light brown to red brown nodules. These gravels are commonly also bauxite ore grade and could be part of the deposit extracted for crushing and screening.The bauxite oreAluminum Mineral Processing and Metallurgy: Iron-Rich,,27.03.2018· Red mud is the solid waste residue generated from the alumina refining of bauxite ore, primarily by the Bayer process which utilizes caustic soda to dissolve the aluminum silicate. Approximately, 35–40% of the processed bauxite ore goes into the waste as alkaline red mud slurry which consists of 15–40% solids, and 1.0–1.5 tons of red mud is generated per ton of alumina

Bauxite Extraction Process — WORLDVEST PARTNERS

Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
