The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.

Bauxite deposits occur in at least 50 countries, with estimated world reserves of approximately 30 billion tons. In 2020, the global production of bauxite amounted to approximately 371 million metric tons, while about 79% of the ore was refined to produce alumina, and the remainder was used for a variety of products, e.g., abrasives and …
2. Preliminary crushing of the screened aluminum ore by the jaw crusher. 3. The spiral classifier classifies the ore powder ground by the ball mill again. With the low-speed rotation and continuous stirring of the spiral classifier, most of the light and fine bauxite ore particles are suspended on the surface and overflow from the overflow weir.
The bauxite ore is then fed into a crusher. The crushed bauxite ore is then fed into a screen. The screened bauxite ore is then collected in different bins, depending on the size of the ore. The crushing and screening process is an important step in the production of bauxite. The process breaks down the bauxite ore into smaller pieces …
