  • Iron ore

    The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals

  • MHI Cascade e Ion Plasma Case Studies

    Is there a simple way to tell if the Cascade e Ion Plume treated part is smoother? Yes, when nitrided or oxy nitrided with the GoldenBlue treatment, the swage lock, high temperature bolt, ball/roller bearing or machine tool should make less noise when machining, or when putting on the nut. Less noise is an indicator of smoothness.
