Hematite, magnatite, limonite, taconite and siderite are some types of iron ore. Hematite has about 70% pure iron and magnatite about 72% while taconite has only about 40%.
Some iron ore contained vanadium producing so-called 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.

Ore - Wikipedia, the free encyclopedia. An ore deposit is one occurrence of a particular ore type. Most ore deposits are named according to either their location (for example, the Witswatersrand, South Africa), or after a discoverer (e.g. theThe classifications below are typical.Hydromagmatic magnetite iron ore deposits and skarns.
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Types of Ore Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock .
This chapter reviews current iron ore comminution and classification technologies and presents some examples of flowsheets from existing operations. New trends and advances in comminution technologies are presented and discussed, particularly with regard to the impact on energy, operating, and capital costs.

Types of iron ore: Hematite. Hematite gets its name from the Greek word for blood, haima, because of its reddish color. This is one of the types of iron ore that has very high iron content, and although the iron content of hematite itself is lower than that of magnetite, the mineral sometimes occurs in higher-grade deposits, often referred to as direct-shipping ore (DSO).
