The crystalisation process is driven by progressive cooling of the pregnant liquor, resulting in the formation of small crystals of aluminium trihydroxite (Al(OH) 3, commonly known as “hydrate”), which then grow and agglomerate to form larger crystals. The precipitation reaction is the reverse of the gibbsite dissolution reaction in the

Aluminum Processing Equipment Process Flow

2021-2-15  Aluminum is the most abundant metal element in the Earth’s crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

Chapter 2. Production and Processing of Aluminum

1999-5-7  The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.
