Bauxite 101 | The Aluminum Association
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. Approximately 70 percent of the world's ...

Manufacturing
(Pakistan, ) Aluminium production starts with the raw material bauxite, which is a clay like soil type found in a belt around the equator (Hydro, 2016). This bauxite is mined from a few meters only below the ground. The bauxite is then transported to plants where the clay is washed off and the bauxite passes through a grinder.

Project Report
The Bayer process dissolves bauxite (Aluminium Ore) in sodium hydroxide at elevated temperatures. Alumina Trihydrate is then separated from the solids that remain after the heating process. The solids remaining after the Alumina Trihydrate is removed is highly toxic and presents environmental issues. COST ESTIMATION Plant Capacity MT/day

The Aluminum Manufacturing Process
The Bayer Process Aluminum manufacturing begins with bauxite, an ore that consists of aluminum oxide, iron, and other metals. As soon as the bauxite is mined, it's subjected to the Bayer process—a method named in honor of the Austrian chemist who developed it in the late nineteenth century.
