Mining and Refining – Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. 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 is usually classified according to its intended commercial application: abrasive, cement, chemical, metallurgical and refractory. Approximately 85% of the world's bauxite production is metallurgical bauxite and the alumina is extracted from the bauxite in a refinery using a wet chemical caustic soda leach process known as the Bayer process.

Bauxite, a naturally occurring, heterogeneous material, is the most important raw material used in the production of aluminium (ATSDR, 1999; Dinman, 1983). Bauxite is made up primarily of one or more aluminium hydroxide minerals together with various mixtures of silica, iron oxide, titania, aluminium silicates, and other impurities in minor or trace amounts.

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3).It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.

Aluminium Oxide This grain is derived by refining bauxite ores in an electric furnace. The bauxite is first heated to drive off moisture and then mixed with coke and iron borings to form the furnace charge. After the mixture has been fused and cooled, the resulting rock–like mass is crushed and screened into various sizes.
