Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of the metal aluminum. Bauxite is named after the French village of Les Baux, where it was first recognized as an aluminum ore.
Bauxite: Bauxite, rock largely composed of a mixture of hydrous aluminum oxides. 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,
The chemical and physical properties of bauxite residues are determined by the nature of the bauxite and the effect of the Bayer process. The technology and operating procedures at individual refineries will impact the water content and pH value of the material being discharged - two key factors in bauxite residue management.

Bauxite residue has been studied extensively for the valuable metals found within it, such as rare earth elements. One aspect of its exploitation is to selectively leach rare earth metals, leaving lower-value metals such as iron undissolved.

Bauxite is the primary ore of aluminum. Almost all of the aluminum that has ever been produced has been extracted from bauxite. The United States has a few small bauxite deposits but at least 99% of the bauxite used in the United States is imported. The United States is also a major importer of aluminum metal.
Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal.
Bauxite is the main source of the rare metal gallium.  During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor.
Gallium is a chemical element with symbol Ga and atomic number 31. It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and thallium.Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. Elemental gallium is a soft, silvery blue metal at standard ...
Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived.
Hidden values in bauxite residue (red mud): Recovery of metals. ...

• Hence, threshold value of Silica in bauxite ore should be based on T. Silica content (<5%), rather than R.Silica which can also be controlled during mining. ... (aluminous laterite & PLK/PKK) as well as precious metal (Ti & Va) recovery from Red Mud. Application of SURFACE MINER.
Bauxite is refined into alumina through the Bayer Process summarised below. Alumina (aluminium oxide) is a white granular material produced from the refining of bauxite. Around 90 per cent of the world's alumina is smelted to produce aluminium metal.
Thanks to CRU's multi-commodity and economic expertise, market insights are developed with a deep understanding of mining and metals interdependencies to give you a solid industry-wide view. CRU's aluminium raw materials prices service includes the CRU Alumina Price Index and CRU Bauxite Price Index, updated weekly.
Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal globally, although some clays and other materials can be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.
Dec 20, 2018· Bauxite is also a metal mineral that has high import value in China. In 2017, its import value reached USD 3,445 million . Because of low unit price, the …
Jan 12, 2019· Electrolysis is used to separate electrolyte components by the electric current, Electrolytic cells are used in Electroplating, Purification of metals, Extraction of aluminum from bauxite, Electroplating is the process of the formation of a thin layer in a certain metal on the surface of another metal to give it a nice shiny view or to protect it from corrosion.

Resulting from the heightened environmental awareness of the 1970s, the worldwide emphasis on recycling, including nonferrous metals such as aluminum, has reduced the value of some bauxite ores by depressing the price of aluminum metal.
