Ilmenite. Ilmenite is named after the Ilmenski mountains in Russia where the mineral was first discovered. Ilmenite is slightly magnetic, which means that magnets can be used to separate it from other minerals in sand deposits. It is able to withstand extreme temperatures and is used in the steel industry to line blast furnaces.

species assigned to hematite, ilmenite, and a small amount of tetrahedral Fe3 are present. Magnetic properties at high and low T also indicate that the only magnetic minerals are ilmenite and hematite. Magnetic data suggest that ultra-fine hematite lamellae are magnetically ordered, and their resultant remanent magnetic anomalies may contribute
