The world iron ore resources in Australia, Brazil, Russia, Ukraine, Kazakhstan, India, the United States, Canada, South Africa and other countries.
Iron is found the earliest use of the most widely used, the dosage is also up to a metal, about 95 percent of its consumption accounting for metal consumption. Iron ore for the steel industry, smelting carbon content of pig iron (carbon content is generally more than 2%) and steel (carbon content is generally below 2%). Pig iron is usually for different purposes is divided into steel-making pig iron, cast iron, alloy pig iron. Steel elements are divided into carbon steel, alloy steel. Alloy steel is carbon steel on the basis of, and who wish to improve or get some performance by adding an appropriate amount of one or more elements of steel, join the types of elements in the steel, mainly chromium, manganese, vanadium, titanium, nickel, molybdenum, silicon. In addition, the iron ore used to make synthetic ammonia catalyst (pure magnetite), natural mineral pigments (hematite, specularite, limonite), feed additives (magnetite, hematite, brown iron ore ) and the valuable constructive criticism (magnet), but the amount is very small. Iron and steel products are widely used in various departments of the national economy and people’s lives in all aspects of the basic materials necessary for the social production and public life. Since the mid-19th century invention of converter steelmaking method gradually formed the large-scale production of iron and steel industry, iron and steel has been the most important structural materials occupy very important position in the national economy, is an important pillar industry of social development, is the most important modern industrial and the most widely used metal materials. Therefore, it is often steel, steel production, variety and quality as an important indicator of measuring a country’s industry, agriculture, national defense and science and technology development level of the.
