Two to three tonnes of bauxite are required to produce one tonne of alumina 90 of the global alumina supply of around 90 million tonnes is used in aluminium production Alumina refineries tend to be located close to bauxite mines andor ports for efficient transport of raw materials and of the final productGet Price
Alumina is produced from bauxite an ore that is mined from topsoil in various tropical and subtropical regions The Bayer process discovered in 1887 is the primary process by which alumina is extracted from bauxite To produce pure aluminum alumina is smelted using the Hall–Héroult electrolytic processGet Price
Mar 11 2019 · A typical Bayer plant generates from 1 to 25 times as much red mud as alumina produced with an average of 175 tonnes of red mud per tonne of alumina this ratio is dependent on the type of bauxite used in the refining process and the extraction conditionsGet Price
The Bauxite AR facility was opened as a bauxite refinery in 1952 In 1954 and later in 1959 parts of Alcoas chemical processes in East St Louis Illinois were transferred to the Bauxite facility The facility acted as a combination chemical and refining plant until the Arkansas bauxiteGet Price
Reynolds began exporting bauxite from Ocho Rios in June 1952 and Kaiser followed a year later from Port Kaiser on the south coast Alcan built the first alumina processing plant near its mines at Kirkvine Manchester and in early 1952 began shipping alumina from Port Esquivel This was the beginning of the industry in JamaicaGet Price
