Bauxite Mining Aluminium is the third most abundant element in the Earth’s crust, but does not occur as a metal naturally. The first step in producing aluminium is mining its ore – bauxite.Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits ...
The Process of Mining Bauxite. by Dajcor Aluminum. Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. Before mining can commence the land needs to be cleared ...
Sustainable Bauxite Mining Guidelines ii Executive summary . Bauxite, the primary ore used to make aluminium, is refined into alumina, which is then smelted into aluminium. Other uses of alumina include chemical grade applications. Bauxite demand has historically been met by a few large players in the market, which have operated large scale mines.
Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines.
The Bauxite Community Development Programme is a programme of special funding for communities near bauxite and alumina operations which face a number of challenges including the effects of noise, dust, plant odours, spillages, a reduction in agricultural lands, the dereliction of mined-out lands and relatively low levels of infrastructural development and employment.

Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world’s bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process. Mining bauxite
Although bauxite, used to make aluminum, is one of the most abundant minerals in the Earth’s crust, the Weipa deposits are enormous. Discovered in 1955 by geologist Harry Evans, the miles of reddish bauxite cliffs found on the Cape York Peninsula contain approximately one-quarter of the world’s known reserves of this valuable mineral.

Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3), and occurs as two main types: trihydrate (“low temperature”) bauxite and monohydrate (“high temperature”) bauxite . The other main indicator of bauxite quality is the silica content, usually reactive silica for a low temperature bauxite or total silica for a high temperature bauxite

Indeed, CRU’s July 2015 long-term market outlook for bauxite and alumina estimates global alumina capacity to grow by 29.6%, reaching 179.6 million tonnes by 2024. Metallurgical-grade alumina capacity expansion, primarily in China, is expected to be the main driver for this growth.
The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
