Case study bauxite residue management at Rio Tinto Alcan

After the third stage expansion has been completed, the alumina production will be increased to Mtpa. Due to the global financial crisis, the full capacity has not yet been fully utilised and the alumina production was Mtpa in 2009. Bauxite at Gove is mined by open cut methods and transported to the refinery 19 km by overland conveyors.

In 1956 DEMBA started construction of the alumina refinery which began production in 1961. Most of British Guiana''s bauxite was shipped as raw ore to the parent companies'' plants in Canada and the United States, but a small proportion was calcined. With the opening of the alumina plant, a quantity of alumina was extracted and exported.

How Aluminum Works

The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure. The sodium
