1. Introduction [2] The hemo-ilmenite ores from the Allard Lake area, Quebec, have been of interest for their magnetic properties since the 1950s [Hargraves, 1959a; Carmichael, 1961].Nearly 50 years later, Hargraves' interest was rekindled in these rocks with the discovery of magnetic anomalies on Mars and with the concept of lamellar magnetism …
Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, IiO2, an important pigment, whiting, and polishing abrasive. Ilmenite has a high resistance to weathering. When rocks containing ilmenite weather, grains of ilmenite ...
Ilmenite, iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (FeTiO3), that is used as the major source of titanium. It forms solid-solution series with geikielite and pyrophanite in which magnesium and manganese, respectively, replace iron in the crystal structure.

Ilmenite has served as an effective indicator mineral for more than 40 years due to its resistance to chemical and physical weathering. As a result of its relatively high density compared to other indicator minerals, ilmenite grains often accumulate in placer deposits downstream from a kimberlite source. Although the ideal formula for ilmenite ...
