3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.

An electrical current is run through the mixture, causing the carbon from the carbon anode to attach to the oxygen component in the alumina, yielding aluminum and carbon dioxide: 2 Al2O3 + 3 C > 4 Al + 3 CO2. This process takes place at temperatures between 940-980º C and yields an aluminum of high purity.

Bauxite has developed a reputation for being difficult to hydraulically transport. This is about to change with the first long-distance slurry pipeline. The 250-km-long, 10 MT/y capacity pipeline was designed by PSI. Several other pipelines are currently being considered for transportation of bauxite. It will be shown that a properly designed ...

Abstract. It is a well known fact that bauxite was discovered in France near the village of "Les Baux de Provence" in 1822, by a chemist named Berthier, who found an ore which was rich in alumina and poor in iron. But only a few know that the original name was "Beauxite" after the name of the village which at that time was "Les Beaux".
Abstract: Red mud waste residue management has been a consistent issue for review within alumina refinery operations. With 1 to 2.5 tons of red mud residue per ton of Al2O3 produced, the various options must be carefully considered. In light of the 2010 red mud pond dam failure at the Ajka refinery in Hungary, all eyes are on the problem and actions …
Benny E. Raahauge and Fred S. Williams. Abstract This book centers on the production of purified alumina (Al2O3) that is used as a feedstock to smelting cells that convert alumina to purified aluminum (Al). The smelting process used universally around the world for the production of aluminum is known as the Hall-Heroult process.
Prior to joining FL in 1974, he worked as plant engineer for the Danish Sugar Factories. Mr. Raahauge has more than thirty-six years of experience in the calcination of alumina hydrate to alumina, including research and development, process development and design, engineering, and dynamic simulation of gas suspension calciner.

Red mud bauxite residue management is a critical issue for alumina refineries. For every single ton of Al 2 O 3 produced in the alumina refinery, as much as 2.5 tons of red mud residue must be handled. Depending on the bauxite ore grade and the geographic location of the alumina refinery, the amount of residue will vary.

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 …

Bauxite digestion conditions should provide not only the maximum alumina recovery from raw material into liquor, but also the required desilication to produce further alumina of high quality. Several desilication circuits are common for alumina industry, namely low temperature predesilication of crude and digested slurry, Sumitimo process.
