Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

Bauxite ore is the world’s main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide.

The Refinery is the first alumina refinery in the Middle East; it can produce 1.8 million tonnes per year of alumina, all of which almost 80% are processed in Ma'aden’s Smelter, while the rest exported globally. The bauxite and alumina is under the operation of Ma’aden MBAC.

Alumina is a white granular material, a little finer than table salt, and is properly called aluminium oxide. Aluminium does not occur as a metal, but must first be refined from bauxite into alumina.Approximately two tonnes of alumina are required to produce one tonne of aluminium.

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:

Around two tonnes of alumina is required to produce one tonne of aluminium. Across our business we produce about 5.3 kilotonnes of alumina a year. We mine and refine bauxite into alumina at South32’s Worsely Alumina and Brazil Alumina. We smelt alumina into aluminium at South32’s Mozal smelter and our Hillside smelter.

Alumina. Bauxite is the raw material for the production of aluminum trihydrate and ultimately alumina or aluminum oxide. Depending on the quality of the ore, anywhere between two to four tons of bauxite is required for each ton of alumina produced. Alumina is most widely known as the feed for the production of aluminum metal.

Bauxite mining in the United States produced an estimated 128,000 metric tonnes of bauxite in 2013. Although the United States was an important source of bauxite in the early 20th century, it now supplies less than one percent of world bauxite production.

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the

4 The objective of this Alumina Technology Roadmap is to identify the alumina industry’s collective vision of its operating environment in some 15-20 years time, and the goals it must achieve to reach this vision. The Roadmap focuses on the production of (smelting grade) alumina as feedstock for aluminium metal produc- tion.

The alumina is then used to produce aluminum sheets or casts serving as the basis for the numerous aluminum products we consume on a daily basis. It takes approximately six tons of bauxite ore to produce one ton of aluminum. In addition to the production of aluminum, bauxite can be processed in a rotary kiln to remove moisture.

The Bauxite, AR facility was opened as a bauxite refinery in 1952. In 1954 and later in 1959, parts of Alcoa's chemical processes in East St. Louis, Illinois were transferred to the Bauxite facility. The facility acted as a combination chemical and refining plant until the Arkansas bauxite
