Distinguishing features . Ilmenite is often recognised in many altered igneous rocks (which is most, to some extent) by the production of the white pseudo-mineral leucoxene.Often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimed ilmenite.

Ilmenite has been mined both from rocks and beach sand deposits. Ilmenite occurs as accessory minerals in igneous and metamorphic rocks which upon weathering, transpor tation and concentration by wave action yield the placer deposits3. These are the secondary deposits of ilmenites. The rock deposits are the primary deposits of ilme-nites.
V-6. Mining and Beneficiation of Lunar Ores. RICHARD J. WILLIAMS, DAVID S. McKAY, DAVID GILES AND THEODORE E. BUNCH. The beneficiation of lunar plagioclase and ilmenite ores to feedstock grade permits a rapid growth of the space manufacturing economy by maximizing the production rate of metals and oxygen.
Ilmenite is a common accessory mineral found in metamorphic and igneous rocks.It is found in large concentrations in layered intrusions where it forms as part of a cumulate layer within the silicate stratigraphy of the intrusion. Ilmenite generally occurs within the pyroxenitic portion of such intrusions (the 'pyroxene-in' level).. Magnesian ilmenite is indicative of kimberlitic paragenesis ...
