Mineral Properties and Uses



What is Ilmenite?



Ilmenite is an iron titanium oxide and the primary ore of titanium. It is a common accessory mineral in igneous rocks such as gabbro, diorite and anorthosite. It is also forms in veins and pegmatites. Most of the commercially produced ilmenite is recovered from sands that have formed from the weathering of ilmenite-bearing rocks. The ilmenite sand is recovered by dredging and processing the alluvial deposits.

Uses of Ilmenite?



Ilmenite is the primary ore of titanium. It is also used in the manufacture of titanium dioxide for paint pigments. Titanium is used to manufacture a wide variety of metal parts where light weight and very high strength are needed. Examples include: aircraft parts, artificial joints for humans and sporting equipment such as bicycle frames. Titanium is also used in a number of high-performance alloys.
