Difference Between Hematit And Magnetic Iron Ore Ndash Grinding
difference between hematite and magnetite iron ore. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons) Haematite is a slighty lower quantity of iron of about 60%-70% but the Magnetite ore is a finest high quality iron with 70% iron.
