One of the first applications discovered for Hematite was used in making paints and paintings. Hematite was used as a red chalk for some of the earliest writings in human history. Hematite gemstones are considered to be very strong healing stones. They are mostly used to relieve and reduce blood disorders; It is one of the most popular stones available today, especially when combined with the powers of blood stones. Hematite is believed to stimulate iron absorption, which in turn provides oxygen supply and flow to the body.
This stone is considered as a stone that has pain relieving properties. Mentally, it is believed to help calm the mind and eliminate disturbing thoughts to increase concentration and attention. Hematite is also important for Chinese feng shui, because of its protective power and energy to the person who uses it. In general, Hematite is an important gemstone for mental, physical and psychological adaptation and healing. Jewelry and decorations applications has been very popular for hematite. This iron ore is still used to make jewelry.
Application of Hematite powder in drilling industry
One of the most important applications of Hematite is in the drilling industry. Hematite powder can be used as a weighting agent in drilling mud. It must be noted that composition of drilling mud depends on many factors. For example, Hematite is used in the drilling industry to control hydrostatic pressure. For a complete review of Hematite application in drilling industry, please review the article.
Other Applications of Hematite powder
Hematite, along with magnetite, is a major source of world steel production. Hematite application in steel industry is one of the important uses of Hematite produced by TEAM Company. Hematite application in construction industry and the paint industry is also very important.
The difference between Hematite and Magnetite
In this section, the difference between Hematite and Magnetite will be examined as the most important Iron minerals in nature: Magnetite has the chemical formula Fe3O4 and Hematite has the chemical formula Fe2O3. The main difference between Hematite and Magnetite is that iron in Magnetite is in the +2 and +3 oxidation states, while in Hematite it is only in the +3 oxidation state. Magnetite iron ore has a magnetic property, while this property does not exist in hematite as noted before.
4(Fe2O3.FeO) + O2 = 6Fe2O3 ΔH = – 119 Kj/mole
The regenerative capacity of magnetite iron ore is the lowest compared to hematite. Therefore, this mineral must be converted to other minerals such as Hematite in order to be regenerative. It seems that the low regenerative property is the disadvantage of magnetite iron ore. Therefore, its price should be lower than hematite, but in reality this is not the case. In the process of oxidation of magnetite to hematite, a significant amount of heat is released. This process is given in the following equation
4(Fe2O3.FeO) + O2 = 6Fe2O3 ΔH = – 119 Kj/mole
Magnetite iron ore is more valuable than Hematite iron ore. For this reason, the price of Magnetite iron ore is higher than the price of Hematite . Another difference between Hematite and Magnetite is their color. Magnetite is black, but Hematite comes in a variety of colors. Hematite has a reddish brown color. These two substances also have different crystal structures.
Where can Hematite be found?
Hematite is one of the most important sources of iron ore so there is a lot of investment in its mines. Some of the largest mines extract about 100 million tons of iron ore a year. These open pit mines can extend to several miles deep. China, Australia, Brazil, India, Russia, Ukraine, South Africa, USA, Canada, Italy, Cumberland, UK, Brazil, Mexico, Alba Island, Germany, New Zealand are the world Hematite supplier leaders in iron ore production As you know, another name for Mars is Red Planet. NASA has discovered large amounts of Hematite in the soil of Mars. That’s why the surface of Mars is reddish-brown at night. Scientists believe that water once existed on Mars, because Hematite formed in aqueous sediments.
Iran is another country rich in iron ore. In Iran, most iron ores are Hematite or magnetite. The provinces of Kerman, Khorasan Razavi, Semnan, Zanjan, Kurdistan, Hormozgan and Fars have rich resources of Hematite iron ore reserves. In some parts of Hormozgan province, Hematite mines have high reserves such as 300 million tons and 100 million tons. Hormoz Island in Iran, which is very famous for its red soil, has significant reserves of this iron ore. In general, Hematite is usually formed by the accumulation of sediment in places where there is standing water or hot springs. It can also be caused by volcanoes.
