(a) hematite (Fe 2 0 3 ), magnetite (limonite (2Fe 2 0 3 .3H 2 0), and siderite (Fe 2 C0 3 ). The hematite ore or red-ochre is called ‘ox ide of iron’. It has ferrous content ranging from 60 to 70 . It is mainly found in the Dharwad and Cuddapah rocks of the Peninsular India.
However the iron ore of Goa is of inferior limonite and siderite variety. Types of Iron Ore ADVERTISEMENTS In India, Iron ores of magnetite, haematite and limonite are found. (i) Magnetite (Fe 3 O 4) This is the best quality of iron ore and contains 25 to 62 per cent pure iron. It possesses magnetic property and is called magnetite and is.Sep 25, 2019 Important iron ores are haemetite, magnetite, limonite, iron pyrite, siderite. Haematite is most commonly used for the iron extraction process. Thermal decomposition of any compound in a limited supply of air or in the absence of air is known as calcination. Smelting involves the use of reducing agents like C, H2 etc for the extraction of metal.Limonite and siderite contains less iron than hematite.

Siderite ore – Siderite ore (Fig 3) is an iron carbonate with a chemical formula of FeCO3 (iron carbonate), a theoretical iron content of 48.2 , a FeO content of 62.1 , and a CO2 content of 37.9 . Common in nature is hard and dense siderite, the appearance of the colour is gray and yellow-brown, the specific gravity is 3.8, the hardness is between 3.75 and 4.25 n.
Magnetite is a very common iron oxide (Fe 3 O 4) mineral that is found in igneous, metamorphic, and sedimentary rocks. It is the most commonly mined ore of iron. It is also the mineral with the highest iron content (72.4 ). Identification of Magnetite. Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a.The earth's core is composed of metallic iron, and iron compounds form 1.5 of the lithosphere, making iron the eighth most abundant element.
