Mineral Resources

• The mining sector is an important segment of the Indian economy. Since independence, there has been a pronounced growth in mineral production both in terms of quantity and value.

Introduction

• A mineral is a naturally occurring substance with a specific chemical composition and distinct physical properties.
• Minerals exhibit uneven distribution across Earth's surface, concentrating in specific areas or rock formations. They form through natural processes, devoid of human intervention, and can be distinguished by physical properties like color, density, hardness, and chemical characteristics such as solubility.
• Minerals play a crucial role as the foundational materials for the social and economic development of a country. India, rich in diverse minerals, has concentrated deposits in specific regions.
• The abundant and easily accessible mineral reserves have fostered the growth and development of India's mining sector.

Classification Resources of Mineral

• On the basis of chemical and physical properties. minerals are classified into two major mineral resources; metallic and non-metallic
• Metallic minerals are those that contain metal in their crude form, characterized by hardness, heat and electricity conductivity, and a characteristic luster. Examples of metallic minerals include iron ore, bauxite, and manganese ore, further categorized into ferrous and non-ferrous minerals.
• Ferrous Metallic Minerals: Comprising iron-based minerals such as iron ore, manganese, chromium, nickel, cobalt, and tungsten.
• Non-Ferrous Metallic Minerals: Lacking significant amounts of iron, examples include copper, gold, zinc, silver, platinum, and aluminum.
• Non-metallic minerals encompass both organic and inorganic types. Organic minerals consist of petroleum, coal, and natural gas, while inorganic minerals include mica and limestone.

The Mineral Belt of India

• In India, mineral belts play a crucial role in resource distribution. The Chhota Nagpur plateau region holds more than 90% of the country's mineral wealth, with significant coal reserves in the Gondwana troughs. 
• Madhya Pradesh boasts reserves of manganese-ores, coal, limestone, and bauxite.
• Tamil Nadu holds workable deposits of lignite, manganese, mica, and limestone, while Karnataka is a major producer of gold, iron, porcelain clays, and chrome ores. Andhra Pradesh possesses reserves of inferior-quality coal and mica, while Kerala concentrates heavy mineral sands.
• Rajasthan is rich in copper, silver, lead, zinc, uranium, mica, precious stones, and low-grade coal. Gujarat and Assam contribute to petroleum production, with Gujarat also supplying about 90% of the country's fluorite yield. Additionally, Assam has reserves of lignite, and West Bengal is a significant supplier of coal and iron ore.

Mineral Belts and Their Location

Mineral Distribution in India

Iron-Ore:

• Iron-ore serves as the cornerstone of industrial development, constituting about 80% of the total iron-ore reserves in the country, primarily in the form of haematite. India currently stands as the world's fourth-largest producer of iron ore.
• Extracted from igneous rocks located in Cuddapah and Dharwar, major production regions include Gorumahisani, Suleipat, and Badam Pahar in the Mayurbhanj district of Odisha, the Baramjader group extended across Keonjhar and Sundargarh districts of Odisha, Singhbhum district in Jharkhand, Bailadila range in Bastar district in Chhattisgarh, Sandur hills at Bellary Hospet region, and Bababudan hills in Chikkamagaluru district, Karnataka.

• Additional diamond mining regions include Raichur and Gulbarga in Karnataka and Anantapur and Krishna Basin in Andhra Pradesh.

Mica:

• Mica, a vital non-metallic mineral formed in igneous and metamorphic rocks, is valued for its insulating properties in the electronics industry.
• Major mica producers are Andhra Pradesh, Jharkhand, and Rajasthan. India leads global mica production with 60%, with a significant portion dedicated to exports.

Top States for Mica Production:

Gypsum:

• Used in fertilizer, cement, and sulfur production, gypsum is formed in sedimentary rocks. Rajasthan is the largest producer, with 90% of India's production.
• Hanumangarh district in Rajasthan is the primary gypsum-producing region, with additional findings in Bikaner, Jodhpur, Nagpur, Jaisalmer, Doda in Jammu and Kashmir, and Kutch in Gujarat.

Limestone:

• Limestone, associated with calcium carbonate, the double carbonate of calcium and magnesium, or a mixture of the two, is of sedimentary origin.
• Predominantly produced by Madhya Pradesh, Rajasthan, Andhra Pradesh, Gujarat, Chhattisgarh, and Tamil Nadu, limestone is crucial in the cement, iron and steel, and chemical industries.

Gold:

• Gold, a transition metal often occurring in auriferous rocks, is known as an international currency and is extensively used in jewelry manufacturing.
• Mainly found in Karnataka and Andhra Pradesh, prominent gold fields include the Kolar gold field, Hutti goldfield, and the Ramgiri field. Sands of the Subarnarekha river in Jharkhand also yield gold.

• India possesses the largest deposits of thorium reserves globally, followed by Brazil, Australia, and the USA.
• Extracted from monazite sand formed by the disintegration of Precambrian rocks, these monazite extracts are mainly found in the coastal region of Kerala.
• With proper technology development, thorium deposits can fulfill India's power requirements permanently.

Conservation of Mineral Resources:

• Mineral resources are depleting rapidly due to the increasing population and demands, being limited and irreplaceable.
• Conservation methods include strategic and long-term utilization, recycling through scrap metals, improving technology for cost-effective use of poor-grade ores, promoting non-conventional energy sources as substitutes, and training for efficient mineral conservation.

Mines and Minerals (Regulation and Development) Act (1957):

• Enacted by the Indian Parliament, this act regulates the mining sector in India, excluding minor minerals and atomic minerals.
• The act, amended in 2015 and 2016, forms the basic framework for mining regulation in the country.
• It outlines the conditions for obtaining a mining license in India. The extraction of minor minerals falls under the jurisdiction of State Governments, and river sand is considered one such minor mineral. Prior permission from the Ministry of Environment and Forests is required for mining and prospecting on forest land. The Mines and Minerals (Development and Regulation) Act, 2015, amended this act.

The Mines and Minerals (Development and Regulation) Amendment Act, 2015

• The Mines and Minerals (Development and Regulation) Amendment Act, 2015, aimed to introduce transparency in the mining license allocation process through auctions. This amendment proposed an auction-based system for the allocation of mining licenses. 
• A fixed percentage of the mine's revenue would be allocated to the development of the surrounding area, forming a District Mineral Foundation. State Governments would set the rates, in addition to royalty.
•  The amendment also established the National Mineral Exploration Trust to explore and promote non-coal minerals. The validity of licenses was extended to 50 years, with no renewals but only re-auction.

The National Mineral Policy, 2019

• The National Mineral Policy, 2019, introduced measures to boost the mining sector, such as the Right of First Refusal for RP/PL holders, encouragement of private sector exploration, and support for mergers and acquisitions in the mining industry. 
• It proposed creating dedicated mineral corridors, granting industry status to mining activities, and promoting long-term import-export policies for better planning. 
• The policy aimed to rationalize reserved areas given to PSUs through auctions, harmonize taxes and royalties with global benchmarks, and enhance private sector participation.

The Mines and Minerals (Development and Regulation) Amendment Bill, 2021

• The Mines and Minerals (Development and Regulation) Amendment Bill, 2021, presented in Lok Sabha on March 15, 2021, proposed amendments to the Mines and Minerals (Development and Regulation) Act, 1957. 
• Key provisions include the removal of restrictions on the end-use of minerals, allowing captive mines to sell up to 50% of their annual production in the open market, and the central government's authority to conduct auctions in specific cases. 
• Additionally, the bill outlined the transfer of statutory clearances to new lessees for a two-year period after the expiry of a mining lease.
