Major mineral resources of India with maps

Minerals play a vital role in the functioning of industries. All the industries need certain types of mineral resources for the manufacturing of semi-finished and finished goods or even as an energy source. In this article, I shall discuss the major mineral resources of India, their location and distribution, types of minerals, etc. This topic is very important for exams of upsc, bpsc and other state exams. For other important topics related to Indian geography, kindly read the articles of Indian geography.

Minerals and ores

Minerals are the naturally occurring substances of organic and inorganic origin having definite chemical and physical properties. Generally, minerals are found in ores. The term Ore is defined as an accumulation of any mineral mixed with other elements.

Fortunately, India is bestowed with a large number of mineral resources. Since India’s geological structure is the product of ancient hard rocks, therefore, all kinds of mineral resources are found in India.

Occurrence of minerals resources of India

In Igneous and Metamorphic rocks

  • Occur in cracks, crevices, faults or joints.
  • They are forced towards the earth’s surface since these minerals are in the molten and gaseous state.
  • They get cooled and solidified as they rise through the cracks and faults.
  • Examples- Tin, Copper, Zinc and Lead

In Sedimentary rocks

  • Occur in beds and layers.
  • They are formed due to accumulation, deposition and concentration in horizontal layers.
  • Examples- Coal, Iron Ore, Gypsum, Potash, Sodium salt.

Decomposition of surface rocks

  • The removal of soluble constituents.
  • Example- Bauxite.

Minerals of Alluvial deposits

  • They occur in sands of valley floors and base of hills.
  • They are commonly known as Placer deposits.
  • Example- Gold, Silver, Tin and Platinum.

Minerals of Ocean water

  • They are too widely diffused to be of economic significance.
  • Example- Common salt, Magnesium, Bromine and Manganese Nodules.

Classification of Minerals

Based on the chemical and physical properties, minerals can be classified under three broad categories of Metallic, Non-Metallic and Energy minerals.

Characteristics of Mineral resources of India

  • Firstly, mineral resources are unevenly distributed over the surface.
  • Secondly, the low-quality of mineral resources are more in quantity as compared to high-quality minerals. In other terms, there is an inverse relationship between quantity and quality of mineral resources.
  • Thirdly, all the minerals are exhaustible over the period.
  • Moreover, these minerals take long period (over hundreds of years) to replenish.

Regional distribution of Mineral resources in India

Geologically, Indian Peninsular region is endowed with great amount of mineral resources. Over 97% of the total coal reserves of India occur in the valleys of Godavari, Mahanadi, Sone and Damodar. In terms of Petroleum reserves, the sedimentary basins of Assam, Gujarat and Mumbai contain huge amount of petroleum reserves. The following are the three broad belts of minerals in India.

  • North-Eastern Plateau region.
  • South-Western Plateau region.
  • North-Western Plateau Region.

North-Eastern Plateau region

The north-eastern plateau region covers Chhotanagpur in Jharkhand, plateau regions of Odisha, West Bengal and some parts of Chhattisgarh. This region is endowed with rich iron ore, coal, manganese, bauxite and Mica hence, it is a region of major iron and steel industries.

South-Western Plateau region

The south-western plateau region covers the states of Karnataka, Goa, uplands of Tamil Nadu and Kerala. It is rich in both ferrous metals and bauxite. The other important minerals of this region are iron ore, manganese and limestone.

North-Western Plateau Region

The north-western plateau region spreads along Aravali in Rajasthan and parts of Gujarat having Dharwar rocks. The important metallic minerals of this region are Zinc and Copper. In terms of building materials, Rajasthan has rich reserves of Sandstone, Granite, Marble. Apart from aforesaid regions, the Himalayan region of India also has mineral resources like Copper, Lead, Zinc, Cobalt and Tungsten.

Iron ore in India

Iron ore plays a vital role in the development of metallurgical industries. Geologically, the major deposits of iron ore are found in association with Volcano-Sedimentary Banded Iron formation (BIF) of Pre-Cambrian age. The major iron ores are Magnetite, Hematite, Siderite, Limonite and Laterite. Out of these, Magnetite (the best quality iron ore) and Hematite are the most prominent iron ores found in India.

However, the entire production of iron and its products in India come from Hematite reserves as Magnetite reserves are not being exploited fully. The Magnetite reserves of India are mainly found in eco-friendly areas of Western Ghats. According to geologists, around 96% of Hematite reserves are confined in the states of Jharkhand, Chhattisgarh, Odisha, Karnataka and Goa. The remaining reserves of Hematite are constrained in the states of Maharashtra, Madhya Pradesh, Uttar Pradesh, Rajasthan and Assam. Over 85% of the Hematite reserves are of medium grade to high grade having more than 62% of iron content.

Manganese ore in India

Manganese is a Ferro metal, occurring as silvery grey. It is very hard and brittle. It is always present in combination with other minerals like iron, laterite, etc. Being a ferrous metal, manganese is used in steel manufacturing and ferromanganese alloys. It has been estimated that for manufacturing of one tonne of steel, about 10 kg of manganese is required. In terms of other manufacturing industries, it is used in the manufacturing of pesticides, bleaching powder and paint industries. Geologically, manganese deposits are found in association with the Dharwar system.
