Due to its diverse geological structure, India is endowed with a diverse range of mineral resources. After Zimbabwe, India processes the world's second-largest manganese reserves. After China, Gabon, South Africa, and Australia, India is the world's fifth-largest producer. The major manganese ore-producing states are Maharashtra, Madhya Pradesh, Odisha, Andhra Pradesh, and Karnataka. More than half of India's manganese is produced in Maharashtra and Madhya Pradesh combined. This article will explain to you about Manganese Resources in India which will be helpful in preparing Geography for the UPSC Civil service exam.

Manganese Resources in India

• Manganese ore deposits in India are primarily associated with the Gondite Series of Madhya Pradesh (Balaghat, Chhindwara & Jhabua districts), Maharashtra (Bhandara & Nagpur districts), Gujarat (Panchmahal district), Odisha (Sundargarh district), and Andhra Pradesh (Ganjam & Koraput districts) and the Kodurite Series (Archaeans) (Srikakulam & Visakhapatnam districts).
• Opencast and underground methods of manganese ore mining are both used in the country.
• There are 8 underground mines out of 142 total (3 in Madhya Pradesh and 5 in Maharashtra).
• MOIL Ltd, a public sector company, operated seven underground mines, while M/s J.K. Minerals, Balaghat (Madhya Pradesh), a private company, operated one.
• The underground mines are all mechanized or semi-automated.

Importance of Manganese

• Manganese is a silvery grey mineral that is extremely hard and brittle.
• It is always found in the presence of iron, laterite, and other minerals.
• Manganese in alloy form is a critical component of steel production, and steel is one of the most important indicators of a country's industrial economy's growth.
• Manganese ore trade volume has increased globally, including in India, in recent years.
• India is currently one of the world's largest importers of manganese ore.

Transportation of Manganese Ore in India

• Manganese ore is typically transported by trucks from mines to railheads, where it is then transported to ports by rail wagons.
• The ore is transported by aerial ropeways from the MOIL mine in Balaghat district, Madhya Pradesh, to the rail-head loading bins.
• In Goa, the ore is transported in bulk via road-to-river routes up to Mormugao harbor, and in a few cases, by rail where mines are close to railways.
• The ore loading into barges at the river's mouth is done mechanically.

State Wise Distribution of Manganese

Exports

• Over four-fifths of total production is consumed domestically, with only one-fifth exported.
• The manganese exports have been steadily declining due to rapidly rising demand in the domestic market.
• This is due to the expansion of some of the industries that rely on manganese as a primary raw material.

Worldwide Supply of and Demand for Manganese

• Only four countries produced 70% of the world's manganese ore in 2011, in decreasing order of production: South Africa, Australia, China, and Gabon.
• These four countries, plus Brazil and Ukraine, account for 90% of proven manganese reserves.
• The United States, like many other industrialized countries, particularly in Europe, has no manganese reserves.
• In the United States, all manganese ore is imported. Gabon (61%) was the primary source of ore from 2008 to 2011, followed by Australia (21%), South Africa (7%), and Brazil (5 percent).
• Manganese demand has historically tracked steel production and is expected to do so again in the future.

Conclusion

According to the World Steel Association, India's per capita steel consumption was 65.2 kg in 2017, compared to 214.5 kg globally. This disparity in steel consumption per capita reflects opportunities that will inevitably arise for the steel industry, which will have a positive impact on manganese ore demand. The single most important factor influencing manganese ore demand is crude steel production. This reflects the country's strong growth in the steel industry, as steel is the primary market for manganese, accounting for 65 to 70 percent of consumption. India has set a target of 300 million tonnes of steel production capacity by 2030-31. In the coming years, demand for manganese ore is expected to rise to around 10 million tonnes per year. MOIL Ltd, India's largest manganese ore producer, has set a target of increasing production to 3 million tonnes by 2030; however, imports will continue to fill the demand gap in the coming years.

GS Mains Questions and Model Answers

Q1: Discuss the role of manganese in India's industrial sector and its economic importance.\

Answer: Manganese is critical for India's industrial sector, particularly in steel manufacturing where it enhances strength and corrosion resistance. It is also vital for the chemical and battery industries. India is a major global supplier, and its export of manganese contributes significantly to foreign exchange. However, sustainable mining practices are necessary to mitigate environmental impacts, making manganese both economically and environmentally significant.

Q2: Identify the main manganese-producing regions in India and their contribution to the economy.

Answer: Key manganese-producing regions include Madhya Pradesh, Maharashtra, Odisha, and Karnataka, with Maharashtra leading. These states not only support local industries but also contribute to national exports. The mining sector in these areas provides employment, boosts regional economies, and strengthens India’s position in the global minerals market.

Q3: What are the environmental impacts of manganese mining, and how can they be mitigated?

Answer: Manganese mining can cause deforestation, habitat loss, soil erosion, and water contamination from mining waste. Mitigation measures include enforcing stricter environmental regulations, using sustainable mining techniques, restoring mined lands, and monitoring waste disposal to minimize ecological damage.

Previous Year Questions on  Manganese Resources in India

1. UPSC CSE Prelims 2018

Question: Which of the following states is a major producer of manganese in India?

Answer: States like Maharashtra, Madhya Pradesh, and Odisha are prominent manganese producers due to large deposits. Maharashtra, in particular, has substantial reserves around the Nagpur region, aiding India's export strength and supporting the steel industry. The presence of rich mineral resources in these states has made India one of the top manganese producers globally, enhancing industrial capabilities and contributing to economic growth.

2. UPSC CSE Mains 2017

Question: Evaluate the environmental implications of manganese mining in India and suggest measures to address them.

Answer: Manganese mining can lead to land degradation, water pollution, and biodiversity loss, particularly impacting local ecosystems. The discharge from mines can contaminate water sources with heavy metals, affecting communities. Measures to mitigate these impacts include environmental impact assessments, regulated waste disposal, reforestation, and strict enforcement of environmental norms. Sustainable practices like backfilling pits and water recycling can reduce long-term damage, ensuring that economic benefits from manganese mining do not come at the cost of environmental health.
