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.

Chromite: The only mineral ore of chromium metal

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Wisconsin Geological & Natural History Survey » Ilmenite

Formula: FeTiO 3 Hexagonal Description: Ilmenite is a black metallic mineral occurring in tabular crystals or platy masses. It is found as an accessory mineral in many rocks, particularly gabbro and anorthosite. It can be found as a heavy mineral in detrital sediments, although it does alter readily to a mixture of white to yellow titanium oxides known collectively as leucoxene.
