Question

Name the best variety of iron ore found in india

Answer 1

In India we get four types of iron ores, viz. (a) hematite (Fe203), magnetite (limonite (2Fe203.3H20), and siderite (Fe2C03).

The hematite ore or red-ochre is called 'ox­ide 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. It is massive, hard, compact and lumpy ore with reddish or ochre red in colour.

Its chief types are laminated hematite, mi­caceous hematite, and haematite-breccia and hematite quartz-schist. Major portion of India's iron ore de­posits belong to this grade with their concentration in Bihar, Jharkhand, Orissa, Madhya Pradesh, Chhattisgarh, Karnataka, Goa, Maharashtra and Andhra Pradesh.
