  • SPECIAL SECTION/REFRACTORIES: Improving Ilmenite Smelting

    Mar 01, 2009 · This interaction represents a delicate balance in the process and must be maintained by carefully controlling the relative amounts of the process inputs (ilmenite, reductant and electrical energy). The result is that the ilmenite smelting process presents a number of interesting process control challenges.

  • ILMENITE (Iron Titanium Oxide) - Amethyst Galleries

    Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.

    A third mineral, leucoxene, is an alteration of ilmenite from which a portion of the iron has been naturally leached. It has no specific titanium content. Titanium minerals occur in alluvial and volcanic formations. Deposits usually contain between 3 and 12 percent heavy minerals, consisting of ilmenite, rutile, leucoxene, zircon, and monazite.
