Ushing Grinding Ore Metallurgy

Grinding is most often performed with an orewater 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.
