how to grind iron ore fines particle 2

  • Iron Ore FineIron Ore

    Iron ore fines refer to a small particle of high grade direct ship ore. Fines are high quality ground iron ore sands that must be sintered at first to create larger pieces before they can be used in blast furnaces. The grade is between 56 to 66 iron (Fe) with the disadvantageous elements controlled through ore mixing.
