Separation Process Of Iron Ore Iron Ore Magnetic Separation process of iron ore At present there are about 300 kinds of ironbearing minerals found in nature According to their chemical composition iron ore can be divided into magnetite hematite limonite and siderite The specific magnetic susceptibility of the material is different and iron ore is divided into strong magnetic and weak magnetic...It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite- smithsonite, siderite- magnesite and siderite- rhodochrosite solid solution series.Siderite WikipediaLimonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.

Learn Ferrous Minerals in 3 minutes.

Iron is one of the most important ferrous minerals in India. It is used in industries and construction activities and therefore called the backbone of the economy. There are basically four types of iron ore- Magnetite, Hematite, Siderite, and Limonite. Hematite is the most commonly used iron ore. There are 4 major iron ore belts in India.tant iron minerals are magnetite (Fe 3O4), hematite (Fe2O3), and limonite (FeOOH). Meanwhile, other iron minerals such as siderite (FeCO 3) and pyrite (FeS2) are not common to process as metallic iron source. Figure 1 visualized various iron minerals.
