Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.
and ball mills can readily handle bauxite on account of its very soft nature. However, it is the tonnage throughput and the product size that are the two critical factors that must be met in assessing the optimal mill design. Despite the simplicity of open circuit rod mills, the operation of numerous small mills has now become antiquated.
