Bauxite is an aluminum-rich sedimentary rock It is the principal ore of aluminum Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite 4The major impurities are iron oxides and hydroxides (which give reddish color to most bauxites) and clay minerals
In terms of physical properties, Bauxite formula has a different composition What it means is that bauxite contains a mixture of oxides like aluminium hydroxides, hydrous aluminium oxides, and minerals like gibbsite, boehmite and diaspore including some clay mineralsIt also contains, insoluble materials namely magnetite, quartz, siderite, hematite and goethite
Bauxite is not a mineral, but rather a group of aluminum oxid The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and DiasporeBauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of .
The major impurities in Bauxite are iron oxides (goethite & hematite), silicon dioxide, the clay mineral kaolinite as well as small amounts of anatase (TiO 2) Consequently, its composition varies considerably with alumina constituting from about 50% to about 70%
Alumina is a white powder developed by the refining of bauxite The Bauxite and Alumina market is mainly consumption of manufacturing of aluminum, however due to the unique physical and chemical properties, they are used in various other applications
It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source
The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854 Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal
