Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a complete solid solution at

Ilmenite: An ore of titanium Uses and Properties

What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world.

Ilmenite is the primary ore of titanium, a metal needed to make a variety of high

Utilization of Egyptian Ilmenite Ore for Steel Surface

Russia. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the hematite group, but ilmenite has a different crystal form and is not as strongly magnetic. Ilmenite lends it name to a group of similar called ilmenit group, a subgroup of the hematite group of minerals. The general
