Current IAI membership represents over 60% of global bauxite, alumina and aluminium production. Since its foundation in 1972, members of IAI have been companies engaged in the production of bauxite, alumina, aluminium, the recycling of aluminium, or fabrication of aluminium, or as joint venture partners in such. The key objectives of IAI are to:
Such improvements, along with the addition of new, best available technology, refining capacity has driven an almost 10% improvement in global refining energy efficiency in just 5 years. Today, the average specific energy consumption is around 14.5 GJ per tonne of alumina, including electrical energy of around 150 kWh/t Al 2 O 3 .
Our operations include one of the world's largest bauxite mines and the world's largest alumina refinery. Our bauxite mines are located in the state of Pará, in the northernmost part of Brazil. A significant portion of Hydro's bauxite is further processed in the company's own plants, but some of it is also sold directly to other companies.

Rusal suspends all bauxite operations in Guyana on continued unrest Russian aluminium producer UC Rusal is suspending the operation of its Bauxite Company of Guyana (BCGI) business in Guyana on "serious illegitimate actions" but will continue to obtain bauxite supply from its other mines, it said on Monday February 3.
Alcoa of Australia Ltd operates one of the world's largest integrated bauxite mining, alumina refining and aluminium smelting system and supports approximately 4,275 direct jobs, predominantly in regional Australia. Our operations consist of two bauxite mines, three alumina refineries and two dedicated port facilities in Western Australia and Portland Aluminium smelter in Victoria.
In most commercial operations, alumina is extracted (refined) from bauxite by a wet chemical caustic leach process known as the Bayer process. Alumina is smelted using the energy-intensive Hall-Heroult process to produce aluminium metal by electrolytic reduction in a molten bath of natural or synthetic cryolite (NaAlF 6).
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 Jamaica.
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.
