Aluminum - Minerals Education Coalition

Aluminum. Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

Grinding Aluminum

The stone would grind the aluminum for a while, but particles would start getting embedded in the pores of the stone. And the next time the stone comes around, there's no grit exposed, only little bits of aluminum. So the aluminum on the piece rubs against the aluminum on the wheel, producing more heat, which produces more melting, and so on.
