Grinding is most often performed with an ore/water slurry, which reduces particulate matter (PM) emissions to negligible levels. When dry grinding processes are used, PM emissions can be considerable. After final size reduction, the beneficiation of the ore increases the concentration of valuable minerals by separating them from the matrix rock.

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.

Aluminum melts easily, and if you were to try to grind down aluminum, it would start to melt and the aluminum would coat the wheel. 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.
