The Votorantim Group started as a textile factory and was commissioned in 1918 in the municipality of Votorantim, São Paulo state. Since then, Votorantim has been diversifying its activities.ball bauxite process,Our production processes | .alteo-aluminaOur production processes. Today, more than 95% of alumina is produced from bauxite using the Bayer process. Bauxite is the ideal raw material because it contains alumina in a non-combined form and in great quantities (30% to 65%).

Bauxite may be as hard as rock or as soft as mud and may occur as compacted earth (both friable and re-cemented), small balls (pisolites), or hollow, twig-like material (tubules) . Once mined, the next stage in aluminium production is the chemical Bayer Process where alumina (Al2O3) is extracted from bauxite in a refinery.

Studies on Batch Grinding of Bauxite Ore in Ball Mill - International .

Grinding is the last stage in the process of comminution; in which the particles are reduced in size by a combination of impact, abrasion and attrition of the ore by the grinding media such as balls, pebbles or rods in rotating cylindrical vessels known as tumbling mills [1]. In many industries the final product or the raw materials.
