Ilmenite generally refers to raw ore (that is, ore that has not been ore-dressed after mining and contains more impurities), namely crude titanium ore, and more professionally refers to titanium metatitanate (FeTiO3). Ilmenite is an oxide mineral of iron and titanium, and is the main ore for refining titanium. 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 system, the crystals are often plate-shaped, and the aggregates are massive or granular. Steel gray or iron black, metallic luster, Mohs hardness 5 to 6, specific gravity 4.7 to 4.78, weak magnetic. It is found in igneous rocks and metamorphic rocks as accessory minerals and can also form sand deposits. Famous mines include Lake Erad in Quebec, Canada, and Cragro in Norway. Famous producing places of coastal sand mines include Tranwankol 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 values, and are mainly used for quality control of titanium concentrate chemical analysis, calibration of analytical instruments, and evaluation and verification of the accuracy of analytical methods. At present, the price of titanium concentrate in the market is about 700 yuan per ton, and the price is relatively stable.

In your supplementary question, the product listed is an ilmenite alloy, which is not the same thing as ilmenite or ilmenite. Ferrotitanium alloy of titanium and iron. Used as a purification agent for steel. The high-carbon ferro-titanium contains 17% titanium and 7% carbon, and the remaining iron is used as a ladle additive for purifying steel. The low-carbon ilmenite alloy contains 20% to 25% titanium, 0.10% carbon, 4% silicon, and 3.5% lead, and the rest is iron. It is used as a reducing agent and is made of ilmenite in an electric furnace. The price per ton is above 10,000 yuan.
