It can reduce unnecessary investment in equipment to obtain ideal beneficiation results. Ilmenite is a black irontitanium oxide (FeTiO 3) with the main mineral components of hematite, magnetite, pyrite, pyroxene, and amphibole. Ilmenite in placer deposits often contains a large amount of slime. Ilmenite mineral's Mohs scale hardness is 56.
