Mining and Refining – Process - World Aluminium

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.

Primary Production The Aluminum Association

Bauxite to aluminum reduction factors For every 4 pounds of bauxite, 2 pounds of alumina can be produced. From every 2 pounds of alumina, 1 pound of aluminum is produced. Energy conservation trends Per ton of aluminum produced, electrical consumption has been reduced by 50 percent from the levels necessary 50 years ago.

Bauxite: The principal ore of aluminum.

Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Chapter 2. Production and Processing of Aluminum

The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of production steps from the bauxite mine through casting is given in Fig. 2.1.

12.1 Primary Aluminum Production

Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.
