Grading of Bauxite Mines of the World
Bauxite: Bauxite, rock largely composed of a mixture of hydrous aluminum oxides. Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic,

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
