The ore, which is an active ingredient in creating steel, is the world’s most commonly used metal, representing almost 95 percent of all metal used per year. Although prices for iron ore have been extremely unattractive as of late, we examine the process of turning the metal into steel.
Iron ore is converted into various types of iron through many processes. The most common process is the use of Blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace.
Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.
Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron oxide.It is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's continents.

Iron ore tailings mines decomposition products can be widely used in the drilling mud treated process as the natural brown material, and iron ore mines can neutralizing hydrogen sulfide. This passage will have a brief introduction of iron ore mining process. Iron ore mines as the main iron source have been widely used in England and Europe.
Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low -grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. The equipment used

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
