About 7 Mt/year of alumina is produced in Europe, i.e. 7% of the global production which reaches 130 Mt/year. This generates about 5-6 Mt/year of bauxite residue in Europe. The Alumina plants located in Europe are reported in Fig. 2. Fig. 2 Alumina plants located in Europe
Abstract. Bauxite is the main source for alumina production. With the rapid development of iron and steel industry and aluminum industry, high-quality iron ore and bauxite resources become increasingly tense.
Metallurgical-grade alumina (Al 2 O 3) extracted from bauxite by the Bayer process is generally referred to as the ore (Sanders, 2002). 1.2. Manufacturing processes ... has also been detected in the indoor atmosphere of an aluminium-production plant (IARC, 2002; Brusick et al., 2008). 4.1.2. Humans.
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 and/or ports for efficient transport of raw materials and of the final product.
