suitable iron ore magnetic separator for less than 3 mm iron ore

  • Iron ore Wikipedia

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe) .. The typical magnetite iron ore concentrate has less than 0.1% phosphorus,.
