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.
