Ilmenite generally means that du in the bai sense refers to the original ore (that is, ore that has not been beneficiated after mining and contains more impurities), namely crude titanium ore dao, more professionally refers to titanium metatitanate (FeTiO3 ). Ilmenite is an oxide mineral of iron and titanium, and is the main ore for titanium extraction. Ilmenite is heavy, gray to black, with a little metallic luster. The crystals are generally plate-shaped, and the crystals are aggregated into a massive or granular shape.
Ilmenite is the main mineral for extracting titanium and titanium dioxide. Trigonal crystal system, the crystal is often plate-shaped, and the aggregate is massive or granular. Steel gray or iron black, metallic luster, Mohs hardness 5 to 6, specific gravity 4.7 to 4.78, weak magnetic. Found as auxiliaries in igneous rocks and metamorphic rocks, it can also form sands. Famous mines include Eilat Lake in Quebec, Canada, and Cragro in Norway. The famous producing areas of coastal sand mines include Tranwanker in India, Florida in the United States, and the east coast in Australia. In Panzhihua iron ore in Sichuan, China, ilmenite is distributed between magnetite particles or in fissures and forms large deposits.
Titanium concentrate refers to the concentrate obtained after the titanium ore is processed by the beneficiation process. Titanium concentrate requirements: TiO2 content ≥50%; Fe2O3 content ≤13%; FeO content <34%. It is selected from ilmenite or titanomagnetite and is a raw material for producing titanium dioxide with a wide range of uses. Titanium concentrate standard samples can be used as standards for the transfer of value, mainly used for quality control of titanium concentrate chemical analysis, calibration of analytical instruments, evaluation and verification of the accuracy of analytical methods.
