hematite recovery from iron ore waste


Iron Ore - Artifacts

Most large hematite iron ore deposits are sourced from metasomatically altered banded iron formations and rarely igneous accumulations. Hematite iron is typically rarer than magnetite bearing banded iron formations or other rocks which form its main source or protolith rock, but it is considerably cheaper and easier to beneficiate the hematite ores and requires considerably less energy to crush and grind.
