Aluminum is the most common metal element found on Earth, totaling about 8% of the Earth’s crust. However, aluminum as an element is reactive and therefore does not occur naturally – it needs to be refined to produce aluminum metal. The primary starting material for aluminum refining is bauxite, the world’s main commercial source of aluminum.

Beneficiation can begin within the mine itself. Most mines will have a crusher within the mine itself where separation of ore and gangue minerals occurs and as a side effect becomes easier to transport. After the crusher the ore will go through a grinder or a mill to get the ore into fine particles.
