Bauxite is used as raw material by which industry? A. Aluminium: B. Iron: C. Steel: D. Gold: Answer» A. Aluminium Explanation: Bauxite is the principal ore of aluminium. Bauxite is not a mineral. It is a rock formed from a laterite soil that has been severely leached of silica and other soluble materials in a wet tropical or subtropical climate.
AbstractThe most common process step to feed an alumina refinery with bauxite is sizing of the raw bauxite material that is extracted from the mine. The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. ...
Bauxite ore is the world's main source of aluminum. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world's bauxite production is refined through the Bayer chemical process into alumina.
The Bayer Process is the most commonly used method of obtaining alumina from bauxite, and is explored in detail here. The key input materials are the ores bauxite gibbsite, boehmite, or diaspore, caustic soda, and calcined lime. The global average consumption of these inputs is as follows: Raw Material. kg per tonne of alumina. Bauxite. ~ 3,000.
