MOIL Limited Explained

MOIL is India’s largest producer of manganese ore, a Miniratna Category-I central public sector enterprise headquartered in Nagpur, Maharashtra, and formerly known as Manganese Ore (India) Limited. The Government-owned MOIL Limited works a chain of underground and open-cast mines across the Nagpur and Bhandara districts of Maharashtra and the Balaghat district of Madhya Pradesh, and supplies most of its ore to the steel and ferro-alloy industries.

Manganese is a quiet but essential ingredient in modern steelmaking, and MOIL sits at the start of that supply chain. This explainer covers how MOIL began, where its mines are, why manganese matters, what the company sells and how it is expanding into value-added products.

Key Takeaways

• MOIL Limited is India’s largest manganese ore producer and is headquartered in Nagpur, Maharashtra.
• MOIL was formed as a Government company in 1962 under the name Manganese Ore (India) Limited, but the mining roots of its region go back to the late nineteenth century.
• MOIL is a Miniratna Category-I public sector enterprise that reports to the Ministry of Steel.
• MOIL’s mines are concentrated in the Nagpur-Bhandara belt of Maharashtra and the Balaghat belt of Madhya Pradesh, and many of them are underground.
• Manganese, which MOIL produces, is used mainly in steel, where it removes impurities and adds strength and toughness.
• MOIL has expanded into ferro-alloys, battery-grade manganese dioxide and renewable power to earn more from each tonne of ore.

What is MOIL?

MOIL is a Government of India enterprise that mines and sells manganese ore, and it is the biggest company in that business in the country. The name is an acronym of its earlier full name, Manganese Ore (India) Limited, which was shortened when the company adopted its current identity.

The company belongs to the group of Miniratna Category-I enterprises, a recognition given to profitable public sector undertakings that enjoy more financial autonomy than ordinary ones. Its administrative ministry is the Ministry of Steel, which makes sense because the steel industry is its principal customer. MOIL Limited also has publicly traded shares, with the Government of India retaining a controlling stake.

Most of what MOIL sells is ore in graded lumps and fines, but it also has small downstream businesses. These sit alongside the mines rather than replacing them.

What is the history of MOIL?

MOIL’s history begins with private manganese mining in the Central Provinces in the 1890s and became a state enterprise when the Government of India formed Manganese Ore (India) Limited in 1962. The older mines in the Nagpur and Balaghat region had been operated by private firms, and the creation of a Government company brought them under unified public ownership.

Manganese deposits in this belt were recognised in the nineteenth century and were exploited heavily for export during the colonial period, particularly for steelmaking abroad. After independence, the Government sought to organise the sector, secure the mineral for domestic steel plants and modernise the mines.

In the decades since, the company expanded its mines, mechanised operations, opened new shafts and started exploring new areas. It was listed through a public offering at the end of 2010, and it was given Miniratna Category-I status in recognition of its financial record.

Where are MOIL’s mines located?

MOIL’s mines are located in the manganese-rich belt of eastern Maharashtra and the Balaghat district of Madhya Pradesh. The company works roughly a dozen mines, and the names most associated with it include Gumgaon, Kandri, Munsar, Beldongri, Sitasaongi, Dongri Buzurg, Chikla, Tirodi, Ukwa and Balaghat.

The deposits are mostly in the form of steeply dipping ore bodies in old rock formations, which is why a number of mines are underground. Some of them are among the deeper manganese mines in the country, and the company has invested in deeper shafts, ventilation and mechanised drilling.

Underground versus open-cast mining

Underground mining involves sinking shafts and driving tunnels to reach ore, and it is more expensive per tonne than open-cast methods. MOIL has used both methods, though much of its output has come from underground work, particularly as shallow ore has been depleted.

Why is manganese important?

Manganese is important because it is an essential alloying and cleaning element in steel, which is the backbone of construction, transport and manufacturing. Roughly nine-tenths of the manganese consumed worldwide goes into steelmaking, a figure that has stayed broadly stable for decades.

In a steel plant, manganese does three main jobs. It removes sulphur and oxygen, which would otherwise make steel brittle, it adds hardness and strength, and it improves the ability of steel to be rolled and forged without cracking. No widely used substitute exists at comparable cost, which makes manganese a strategic input.

• Steel and cast iron: the largest use, often through ferro-manganese and silico-manganese alloys.
• Batteries: manganese dioxide is used in dry-cell batteries, and manganese compounds feature in some lithium-ion chemistries.
• Chemicals and agriculture: in fertilisers, animal feed and some water treatment applications.
• Aluminium alloys: manganese is added to improve strength and corrosion resistance in some alloys.

What does MOIL produce and sell?

MOIL produces manganese ore in several grades and sells it chiefly to steel plants, ferro-alloy makers and the chemical and battery industries. Grades are classified by manganese content, with high-grade ore suited to ferro-manganese production and low-grade ore blended or used in silico-manganese.

The company also sells small volumes of related products. These include ferro-manganese produced at its own facility, electrolytic manganese dioxide for batteries, and power from its renewable energy projects. In practice, ore sales remain overwhelmingly the largest part of revenue.

MOIL typically sells through a combination of long-term supply arrangements and auctions or price notifications, and it revises ore prices periodically based on market conditions. Because it sells a bulk commodity, its revenues are sensitive to steel demand and ore prices.

How does manganese ore travel from a MOIL mine to a steel plant?

Manganese ore travels from a MOIL mine to a steel plant through a sequence of blasting, hoisting, crushing, sizing, grading and dispatch, mostly by rail and road. After ore is blasted underground or in a pit, it is brought to the surface, where crushers and screens separate it into lumps and fines.

Lumps are the coarser pieces used directly in furnaces, while fines are smaller particles that may need agglomeration, such as sintering or briquetting, before use. Samples are tested in laboratories to assign a grade based on manganese content and impurities such as iron, silica and phosphorus.

Graded ore is stockpiled at mine sites and loaded onto trucks or railway wagons. Customers include integrated steel plants, mini steel plants that make ferro-alloys on site, and independent ferro-alloy producers. Transport cost is a significant part of the delivered price, so proximity to the steel belt of central and eastern India is an advantage.

How are manganese ore grades classified?

Manganese ore grades are classified mainly by the percentage of contained manganese, so a higher percentage means a higher grade and a higher price. As a general guide, high-grade ore is used for ferro-manganese, medium-grade ore for silico-manganese, and lower-grade ore for blending or for steel plants that accept it directly. The exact grade boundaries used in trade can differ by buyer and by official classification.

How is MOIL moving into value-added products?

MOIL is moving into value-added products by producing ferro-alloys, electrolytic manganese dioxide and joint-venture alloys so that it earns more than the raw ore price. The idea is to convert part of its ore into higher-priced intermediate products closer to the end user.

• Ferro-manganese plant: a plant in the Balaghat region that smelts ore into ferro-manganese, an alloy used directly by steelmakers.
• Electrolytic manganese dioxide (EMD): a plant at Dongri Buzurg for battery-grade manganese dioxide, whose use in batteries supports demand outside steel.
• Ferro-alloy joint venture: RINL-MOIL Ferro Alloys Private Limited, a joint venture with Rashtriya Ispat Nigam Limited, the corporate entity of Vizag Steel, for ferro-alloys at Visakhapatnam.
• Renewable power: wind and solar installations, meant to supply electricity to its operations and reduce energy costs.

The scale of these businesses is still modest relative to ore mining, and the company has described value addition as a long-term strategic direction rather than an immediate replacement for mining revenue.

How does MOIL expand its mining capacity?

MOIL expands its mining capacity by sinking new shafts, deepening existing mines, opening new blocks and exploring unexplored areas for fresh reserves. The company has typically run a multi-year programme of mine development, with the aim of raising ore output steadily.

Expansion requires several approvals. A new mining lease needs state and central clearances, environmental and forest clearances and approvals for land use. Underground expansion adds engineering challenges, such as ventilation, dewatering and ground support, which raise costs and take years to complete.

MOIL also invests in exploration, because manganese reserves are finite and richer ore is gradually depleted. Better exploration data helps the company plan capital spending and lease applications long before ore is needed.

Who regulates and owns MOIL?

MOIL is owned by the Government of India, which holds the majority of its shares, and it is regulated by the laws governing mines and minerals in India. Its administrative ministry is the Ministry of Steel, while its mining operations are governed by the Mines and Minerals (Development and Regulation) Act, 1957 and the rules made under it.

As a listed company, MOIL also follows the disclosure rules of the securities regulator and the stock exchanges. Safety in its mines is overseen by the Directorate General of Mines Safety, and environmental compliance is monitored by central and state pollution control bodies.

Like other central public sector enterprises, MOIL is audited by the Comptroller and Auditor General of India, and it signs an annual performance agreement with the Government.

Why does MOIL matter to India?

MOIL matters to India because it secures a domestic supply of a critical steelmaking input, employs people in the mining belt and contributes royalty and taxes to state exchequers. India is among the largest steel producers in the world, and domestic manganese supply reduces exposure to imports.

The company also supports its local communities through health, education and infrastructure initiatives in mining districts. It runs hospitals and schools in or near its townships, and tribal and rural areas near the mines have benefited from its corporate social responsibility activities.

In addition, MOIL’s push into batteries and renewables ties it to India’s wider energy transition. If demand for battery-grade manganese compounds rises, a domestic producer would be well placed to benefit.

What challenges does MOIL face?

MOIL’s main challenges are depleting shallow ore, rising costs of deeper mining, price swings tied to steel demand and competition from imported ore and other domestic miners. Each of these affects its margins, especially since much of the production is underground.

• Depth and cost: as ore gets deeper, the cost of extraction, ventilation and safety rises.
• Market dependence: demand follows the steel cycle, so revenue can fluctuate.
• Clearances: new leases and expansions depend on regulatory approvals that can be slow.
• Safety and environment: mining carries inherent safety risks, and dust, water and land management need constant attention.

MOIL in brief: milestones
