Deposits of Heavy Metals Required for Crucial Industries


azadi ka amrit mahotsav

India has some deposits of heavy metals and critical minerals essential for crucial industries such as Li-Ion batteries, semiconductor technology, and computing. However, the extent to which these deposits are significant and financially viable varies. These deposits are scattered across different regions of the country, with varying levels of accessibility and extraction feasibility. The details are as under:

 

  1. Lithium – India has discovered lithium reserves in the states of Karnataka and Jammu & Kashmir.
  2. Cobalt & Nickel – Cobalt, & Nickel is generally found in association with copper ores. Small deposits are known to exist in Odisha and Jharkhand. India’s reserves are relatively modest.
  3. Rare Earth Elements (REEs) – India has significant reserves of rare earth elements in the states of Andhra Pradesh, Karnataka, Odisha, and Kerala. The monazite sands in Kerala are particularly rich in REEs.
  4. Graphite – India has substantial reserves of high-quality graphite. Graphite is found in Arunachal Pradesh, Jharkhand, and Tamil Nadu.
  1. Further, as per National Mineral Inventory (NMI) as on 01.04.2020, the reserve/resources of critical minerals is given in Annexure-I.

 

          No. Currently, there are no working mining leases for cobalt, nickel, lithium, and neodymium in the country for production purposes.

However, India has mining and production of some critical metals, although it still largely depends on imports to meet its demand. There are 54 mining leases of critical minerals viz. graphite, rock phosphate and tin ore, in the country and the details are as follows :

As regards the steps being undertaken to conduct the exploration of such resources, the Geological Survey of India (GSI) is involved in exploration of critical minerals/metals with special emphasis on exploration of areas, which are potential for critical and strategic minerals and has given thrust to increase the number of exploration projects across the country. GSI has increased its exploration projects for critical and strategic minerals from 118 nos. in 2021-22 to 196 nos. in 2024-25. Since amendment of MMDR Act, 2015, the details of cumulative resource augmented by GSI for critical and strategic minerals at various cut off and different average grade is as follows:

In order to promote exploration of critical and deep-seated minerals, a new mineral concession namely, Exploration Licence has been introduced for 29 deep-seated minerals, of which many are of critical minerals, which will permit the licencee to undertake reconnaissance and prospecting operations for these minerals. GSI has handed over 20 blocks for auction as exploration license to State Governments of which 12 blocks are notified for auction by State of Rajasthan, Karnataka, Maharashtra, Andhra Pradesh, Madhya Pradesh and Chhattisgarh.

In order to encourage private participation in exploration, Ministry of Mines has notified 23 private exploration agencies (NPEAs). These agencies are taking up exploration projects through funding from National Mineral Exploration Trust (NMET).

As regards the mining of such resources, the Central Government has amended the “Mines and Minerals (Development and Regulation) Act, 1957”, in 2023 to empower Central Government to exclusively auction blocks for 24 critical and strategic minerals mentioned in part D to the Schedule-I of the MMDR Act, 1957. So far, 14 critical mineral blocks [Mining Lease-2, Composite Licence-12] have been successfully auctioned having minerals viz., Lithium, Rare Earth Elements (REE), Graphite, Vanadium, Nickel, Chromium, Glauconite, Platinum Group of Elements (PGE) and Phosphorite. These blocks are spread across the States of Bihar, Madhya Pradesh, Karnataka, Odisha, Tamil Nadu, Uttar Pradesh and Chhattisgarh. Earlier, State Governments had auctioned 30 blocks of critical minerals. So far, a total of 44 blocks of critical minerals have been auctioned by the Central Government and various State Governments as per table given below:
