flotation of chromite from the silica

  • Chromite Wikipedia

    Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can

    The chromite glaze problem has been assumed to be the formation of fayalite (ferrous orthosilicate Fe 2 SiO 4 with a melting point of °C) as the reaction product between silica and chromite. Fayalite is not magnetic and so cannot be separated from the sand magnetically. During the recycling of the sand, this low melting point constituent therefore builds up, lowering the refractoriness
