Ore minerals are the minerals within ores that contain the metal. Ores occur as large bodies of rock called ore deposits, which are metalbearing mineral deposits. Types of Minerals Minerals can be divided into: Metallic and Non metallic minerals. Metallic minerals are further divided into Ferrous and nonferrous minerals.
the characteristics of the mineral (such as the quality, size, hardness, iron ore grade, reducibility, mineral/waste rate, and type of deposit), mining processes (type of exploitation, ore processing, available technology), and transportation (distance to cover).

World Class Iron Ore Project. Additional target mineralization is 395 to 540 million tonnes. Within the target area, approximately 200 240 million tonnes have been identified as high grade direct shipping ore ("DSO") with an Fe range of 55 to 62 % Fe. The target extends some 3 km to the West of the Central Zone of the current JORC resource.
Some iron ore contained vanadium producing socalled Damascene steel, ideal for swords. The first person to explain the various types of iron was René Antoine Ferchault de Réaumur who wrote a book on the subject in 1722.
The iron and steel slag that is generated as a byproduct of iron and steel manufacturing processes can be broadly categorized into blast furnace slag and steelmaking slag. Blast furnace. Iron and steel slag refers to the type of metal manufacturing slag that is generated during the process of manufacturing iron and steel products.

Ore:a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue:the valueless mineral particles within an ore deposit that must be discarded.

Changing the type and amount of the elements alloyed with iron can produce different types of steel. The most common steels are: Carbon steels, which contain between % carbon. These are the most common steels and are used for auto bodies, ship hulls, knives, machinery and .
The most important iron ore types found in India are hematite and magnetite. Nearly 61% of hematite ore deposits are found in the eastern part of India and 82% of magnetite ore deposits occur in southern part of India, especially in the state of Karnataka.
Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted.

Iron metalis extracted from iron ore. It never exists in pure form and has to be extracted from iron ore by eliminating the impurities. Gold is the oldest and most precious element to be known. Manganese ore is a silvery brittle or greywhite metallic ore, occurs in many forms and found worldwide.
Mafic Igneous Intrusion Associated Deposits. It is also possible to produce this type of ore through the meteorite impacts, rift/continental flood basaltassociated sills and dykes, volcanic flows and troctolite intrusions. Examples: Sudbury (meteorite impactunusual), Voisey's Bay and Thompson, Canada.
