INDIAN GEOGRAPHY

Detailed explanation-1: -Ferrous minerals contain iron, non-ferrous minerals do not contain iron. Ferrous minerals constitute about 75% of the total production of minerals in India. Iron ore and manganese are two important ferrous minerals mined in India.

Detailed explanation-2: -Our country is well-placed in respect of ferrous minerals both in reserves and production. India is endowed with fairly abundant resources of iron ore. It has the largest reserve of iron ore in Asia. The two main types of ore found in our country are haematite and magnetite.

Detailed explanation-3: -Iron ores are composed of hematite, calcite, and quartz. Two mineralogical types of manganese ores are distinguished: hausmannite and braunite.

Detailed explanation-4: -Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).

Detailed explanation-5: -Haematite and magnetite are the most important iron ores in India. About 79% haematite ore deposits are found in the Eastern Sector (Assam, Bihar, Chhattisgarh, Jharkhand, Odisha & Uttar Pradesh) while about 93% magnetite ore deposits occur in Southern Sector (Andhra Pradesh, Goa, Karnataka, Kerala, & Tamil Nadu).
