What is a high carbon ferro manganese project report?
A high carbon ferro manganese project report is a detailed project report (DPR) for a smelting plant. The plant reduces manganese ore with coke in a submerged arc furnace to make an alloy of about 65–82% manganese and 6–8% carbon. The report sets out the process, raw materials, power load, approvals, project cost, five-year projections, DSCR and break-even.
Promoters use it to size the furnace and raise a term loan; banks and environmental appraisal committees use it to judge whether the plant is viable and compliant.
Also known as: HC FeMn project report, ferro manganese plant DPR, ferro manganese business plan, ferro alloy plant feasibility report.
High carbon ferro manganese plant cost and economics
Our sample report models an 18 metric tonnes per day plant running 330 days a year, or 5,940 MT per year. It starts at 60% capacity, reaches 80% in Year 5 and sells at ₹71,200 per MT.
Raw materials, with furnace power counted among them, take about 63% of sales in Year 3. That leaves a thin margin, so the lowest DSCR of 1.55 in Year 2 is the number a lender will look at first.

High carbon ferro manganese manufacturing process
The alloy is made by carbothermic reduction: carbon from coke strips oxygen from manganese and iron oxides inside a submerged arc furnace. The furnace runs round the clock, so a shutdown costs both output and electrode life.
- Ore preparation
Manganese ore, coke and dolomite are crushed, screened and dried where needed, because fines choke the burden and stop gas flowing up through the charge.
- Batching and charging
The mix is weighed in a set ratio and fed by gravity through chutes from day bins above the furnace.
- Smelting
Electrodes buried in the charge heat it by arc and resistance; carbon reduces the oxides and carbon monoxide leaves as gas.
- Tapping
Alloy and slag are tapped together at intervals into ladles, and the lighter slag is skimmed off.
- Casting and cooling
Metal is cast into beds or moulds and left to solidify before breaking.
- Crushing and sizing
Cooled alloy is crushed and screened to the size class the steel plant orders, from large lumps to 10–100 mm.
- Testing and packing
Each lot is analysed for manganese, carbon, silicon and phosphorus against the grade, then packed in bulk bags.
Which furnace and slag practice should you choose?
Two plants of the same tonnage can have very different costs because of a few design choices made before the furnace is ordered.
| Slag practice | A high-manganese slag practice keeps furnace power lower and sends the rich slag to silico manganese production. A discard-slag practice drives more manganese into the alloy but needs more energy and flux. |
|---|---|
| Product mix | The same submerged arc furnace can switch between ferro manganese and silico manganese. Planning for both protects the plant when one alloy's price falls. |
| Open or closed furnace | Off-gas is rich in carbon monoxide. A closed furnace lets you clean and reuse it for drying or power; an open furnace is cheaper but wastes that energy and needs a larger dust system. |
| Electrodes | Self-baking Soderberg electrodes are fed with electrode paste as they burn away; one disclosed plant plans about 0.03 tonne of paste per tonne of alloy. |
| Captive power | Some larger plants pair the furnace with captive or waste-heat power to escape high grid tariffs; small plants usually rely on a high-tension grid supply. |
Raw materials and consumption norms
Manganese ore is the costliest input, and its grade sets almost everything else. One Maharashtra plant's environmental summary plans about 2.1 tonnes of ore, 0.8 tonne of coke and 0.25 tonne of dolomite per tonne of alloy. In our sample, furnace power is booked as a raw material, as many ferro alloy reports do.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Manganese ore | 55% | 1,025.88 |
| Coke | 20% | 373.05 |
| Power (furnace) | 20% | 373.04 |
| Fluxes | 5% | 93.26 |
| Total | 100% | 1,865.23 |
Sample shares at 70% utilisation. Ore and coke prices move with the steel cycle; your report should use current quotations.
Machinery for a ferro manganese plant
The furnace and its transformer take more than two thirds of the machinery budget. They are sized together in MVA from the daily tonnage and the power you expect per tonne.
| Equipment | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Submerged arc furnace | Smelts the charge; includes shell, lining and electrode system | 250.13 |
| Furnace transformer | Steps grid power down to high-current furnace supply | 90.05 |
| Raw material handling | Day bins, weigh batching and conveyors to the charging floor | 60.03 |
| Crushing and screening | Prepares ore and coke, then sizes the finished alloy | 50.02 |
| Pollution control | Fume extraction and bag filters on the furnace and transfer points | 50.02 |
| Total plant and machinery | 500.25 | |
Costs are the sample report's estimates for an 18 MT per day plant. Get current quotations before you finalise.
Power, water and manpower for the plant
| Electricity | About 2,700 kWh per tonne in CSIR-NML furnace trials. Your tariff per unit decides more of the profit than any machine choice. The sample books ₹373.04 lakh of furnace power under raw materials and ₹195.42 lakh under power and fuel in Year 3. |
|---|---|
| Power connection | A dedicated high-tension supply sanctioned for the furnace load, with a plan for outages, because a cold furnace takes time and electrodes to restart. |
| Water | Mainly closed-loop cooling for the furnace shell, electrodes and transformer. A plant with two 6 MVA furnaces disclosed 10 KLD of process water. |
| Manpower | 90 people in our sample. The furnace runs three shifts, so operators and tappers are needed on every shift, plus a laboratory for alloy analysis. |
| Slag and dust | Space to cool and store slag, and bag filter dust sent to authorised recyclers. |
Licences, environmental clearance and BIS for ferro manganese
Environmental clearance can take longer than building the plant, so approvals belong in the project schedule from day one.
| Environmental clearance | Ferro alloy plants are appraised under item 3(a), metallurgical industries, of the EIA Notification 2006; the projects reviewed for this page were category A, with a public hearing |
|---|---|
| Pollution board consent | Consent to establish and consent to operate from the State Pollution Control Board, with stack monitoring on the furnace |
| Product standard | IS 1171 for ferromanganese, covering grades from FeMn 68 to FeMn 80; BIS lists mandatory certification under a Ministry of Steel quality control order from 8 November 2024 |
| Power | High-tension connection and load sanction from the state power utility |
| Factory and registrations | Factory licence under state rules, Udyam and GST registration |
Requirements vary by state and plant size. Confirm the current position with the authorities before you apply.
Who buys high carbon ferro manganese?
Steelmaking takes almost all of it. The alloy is added in the furnace or ladle to remove oxygen and raise manganese, so demand follows crude steel output in both integrated plants and induction furnace units.
India is a large exporter. The Indian Bureau of Mines reports ferro manganese exports of 638,850 tonnes in 2021-22, up from 335,229 tonnes a year earlier, against imports of 40,881 tonnes.
- Integrated steel plants, which buy through purchase tenders
- Electric arc and induction furnace steel units
- Alloy, wear-resistant and stainless steel makers
- Iron and steel foundries
- Traders and exporters supplying steel mills abroad
Watch the export market: since 18 November 2025 the European Union applies tariff-rate quotas to ferro-manganese imports. India has its own quota, and a variable duty applies once it is used up. An export-led plan should price that in.
Mistakes that weaken a high carbon ferro manganese project report
- Assuming ore grade without checking the ratios
The manganese to iron ratio sets the alloy grade, and phosphorus in the ore passes into the metal. IS 1171 caps phosphorus, so off-grade ore cuts the price you can charge.
- Using an average power tariff
Demand charges, time-of-day rates and outages change the real cost per kWh. A small tariff error swings DSCR more than any other input.
- Ignoring manganese lost to slag
Manganese that stays in the slag is paid for but not sold. The report must show recovery and what happens to the slag.
- Pricing every tonne at the top grade
FeMn 76 and FeMn 72 sell at different rates, and steel plant tenders deduct for low manganese or oversize lumps.
- Leaving out the clearance timeline
An environmental clearance with a public hearing can take many months. Interest during that period belongs in the project cost.

High Carbon Ferro Manganese project report: frequently asked questions
How much does it cost to set up a high carbon ferro manganese plant in India?
Cost depends mainly on furnace size. Our sample report models an 18 MT per day plant at ₹1,021 lakh, including ₹500 lakh of plant and machinery and working capital margin. For scale, a Maharashtra project with two 6 MVA furnaces disclosed a cost of ₹27 crore in its environmental hearing papers. Treat both as indicative; your report should price your own furnace and site.
What raw materials are needed per tonne of high carbon ferro manganese?
Manganese ore and coke are the main inputs, with dolomite as flux. One Maharashtra plant's environmental summary lists about 2.1 tonnes of ore, 0.8 tonne of coke and 0.25 tonne of dolomite per tonne of alloy. Small amounts of quartz and electrode paste are added too. Actual norms depend on ore grade, the manganese to iron ratio and slag practice.
How much electricity does a ferro manganese furnace use?
Furnace trials at CSIR-National Metallurgical Laboratory recorded about 2,733 kWh per tonne of ferro manganese. That makes power one of the largest running costs after ore. The Indian Bureau of Mines puts power at 40–70% of production cost across ferro alloys, which is why tariff and supply terms decide where a plant is built.
Is BIS certification mandatory for ferro manganese?
Yes. The Bureau of Indian Standards lists ferromanganese under IS 1171 with mandatory certification through a Ministry of Steel quality control order, implemented from 8 November 2024. A plant needs a BIS licence and an in-house testing set-up before it sells marked material. Confirm the current standard edition with BIS, because a revision of IS 1171 has been under way.
Is a high carbon ferro manganese plant profitable?
In our illustrative sample, an 18 MT per day plant earns a 21% return on investment in Year 3. It breaks even at 43% of capacity, pays back in about 3.6 years and has an average DSCR of 1.79. Real profit swings with ore and coke prices, power tariff, manganese recovery and export prices, so lenders test each of these.
What is the difference between high carbon ferro manganese and silico manganese?
Both are manganese alloys made in a submerged arc furnace. High carbon ferro manganese carries 6–8% carbon and up to 1.5% silicon under IS 1171, while silico manganese has much more silicon and less carbon. Many plants make both in one furnace and reuse manganese-rich ferro manganese slag as a feed for silico manganese.
Is the sample project report PDF free and can I use it for a loan?
The sample is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report; its figures are representative and not based on a real project, so it should not be submitted to a bank. For a loan, NPCS prepares a report for your own capacity, location and lender.
