Bauxite Crushing Plant. Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.
The bauxite is then transported to the crushing and washing area, reducing the particle size and increasing the available surface area for the digestion stage. The material that is discharged from the mill is called slurry; Digestion: The slurry is pumped to a digester where the chemical reaction to dissolve the alumina takes place. A hot ...
Aluminum (Al) Ore. Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities.
