What is a red oxide pigment project report?
A red oxide pigment project report is a detailed project report (DPR) for a unit that makes red iron oxide (Fe2O3) powder. The unit either roasts ferrous sulphate in a kiln or grinds hematite ore. The report sets out the process, machinery, raw materials, market, project cost, means of finance, five-year projections, DSCR and break-even a lender needs.
Entrepreneurs, paint makers and building-material companies use it to size the plant and raise a term loan; bank officers use it to judge whether the unit can repay.
Also known as: project report on red oxide pigment, red iron oxide project report, synthetic iron oxide plant DPR, red oxide pigment business plan.
What a bank checks in a red oxide pigment project report
A credit officer reads a red oxide report for four numbers that show whether the kiln can pay for itself. These are the values in our sample report and why each one gets questioned.
Copperas is a by-product, so its price and supply move with steel pickling and titanium dioxide output. Banks like to see a supply letter, not just a rate.
The report should show the yield sum: copperas is mostly water and sulphate, so several tonnes go into each tonne of oxide.
DSCR is cash available for loan repayment divided by the instalments due. The sample averages 1.73, but lenders look hardest at the weakest year, when full instalments begin.
Paver block makers and paint companies buy on credit. In the sample, receivables are the largest part of Year 1 current assets, which sets the cash credit limit.
Values are the assumptions in our illustrative sample. Your report uses figures for your route, capacity and buyers.
How much does a red oxide unit cost at different scales?
The process route decides the budget more than the tonnage. A natural oxide unit only grinds ore, while a synthetic unit needs a dryer, kiln, scrubber and washing line.

Red oxide pigment manufacturing process
The sample follows the copperas calcination route, where ferrous sulphate is roasted into ferric oxide. A natural oxide unit skips the first five steps and simply crushes, grinds and classifies hematite ore.
- Dehydrating the copperas
Green copperas crystals pass through a rotary dryer, which drives off most of their bound water before roasting.
- Roasting in the kiln
At roughly 650–800 °C the sulphate breaks down into red ferric oxide; a hotter, longer roast gives a darker, bluer red.
- Scrubbing the kiln gas
The sulphur oxides released in roasting go through a lime scrubber; this is the plant's main emission point.
- Wet milling and washing
The roasted oxide is milled in water and washed repeatedly to bring leftover soluble sulphate down to the buyer's limit.
- Filtering and drying
A filter press removes wash water and a spin flash dryer turns the cake into a dry powder.
- Micronising
An air-classifying micronizer breaks up lumps so very little stays on a 45 micron sieve, which paint buyers check.
- Shade matching and bagging
Each lot is matched against a reference sample for shade and tinting strength, blended if needed and packed in 25 kg bags.
Raw materials for red oxide pigment
By the chemistry alone, one tonne of ferric oxide needs about 3.5 tonnes of copperas, because the crystals are mostly water and sulphate. Losses in washing and handling push the real figure higher, so the report should state its yield assumption.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Ferrous sulphate heptahydrate (copperas) | 76% | 249.67 |
| Hydrated lime for gas scrubbing | 14% | 45.99 |
| Mill scale fines for shade blending | 10% | 32.85 |
| Total | 100% | 328.51 |
Machinery for a red oxide pigment unit
The rotary calcination kiln is the largest single item in the sample, at ₹73.90 lakh. Its lining, burner and temperature control decide shade consistency more than any other machine.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Rotary dryer | Removes bound water from copperas | 34.49 |
| Rotary calcination kiln (oil or gas fired) | Roasts sulphate into red oxide | 73.90 |
| Flue gas scrubber with stack | Captures sulphur oxides from the kiln | 34.49 |
| Wet ball mill | Grinds the roasted oxide in water | 24.63 |
| Washing tanks and filter press | Washes out sulphate and dewaters | 24.63 |
| Spin flash dryer | Dries the filter cake to powder | 24.63 |
| Micronizer with air classifier | Sets particle size and sieve residue | 19.71 |
| Bag filling and stitching machine | Packs 25 kg bags | 9.85 |
| Total plant and machinery | 246.33 | |

Who buys red oxide pigment in India?
Building materials take a large share of red oxide. Paver block, tile and precast makers mix it into cement for a fixed red that will not wash off, so demand follows road, housing and landscaping work.
Paint companies are the second big group, mainly for red oxide primers on steel. They buy to a tighter specification than block makers and test sieve residue, oil absorption and soluble salts on every lot.
- Paver block, interlocking tile and floor tile makers
- Paint and primer manufacturers
- Precast and ready-mix concrete units
- Rubber, plastics and ceramics compounders
- Pigment traders who supply small block yards
Where a new unit wins: buyers switch suppliers when one lot looks different from the last. A unit that holds its shade batch after batch, and keeps retained samples to prove it, wins repeat orders over a cheaper but uneven source.
Licences and standards for a red oxide unit
The pollution category is the approval that differs most between the two routes, so settle the route before you apply.
| Business registration | Udyam (MSME) registration and GST registration |
|---|---|
| Pollution category, synthetic route | Red category: CPCB's January 2025 list places pigments produced by chemical synthesis in Red, so consent to establish and operate carries stricter conditions |
| Pollution category, natural route | Orange category for natural pigments that need no acid, alkali or solvent extraction, as per the same CPCB list |
| Product standard | IS 44:1991, iron oxide pigments for paints, reaffirmed in 2022: Grade 2 covers synthetic red oxide and Grade 3 natural red oxide |
| Factory and fire | Factory licence where worker thresholds apply, and fire NOC for kiln fuel storage where required; rules vary by state |
Mistakes that weaken a red oxide pigment project report
- Costing copperas one to one with output
Each tonne of oxide eats several tonnes of copperas. A report that skips the yield sum understates raw material cost badly.
- Leaving the scrubber out of the budget
Roasting releases sulphur oxides. Without gas treatment in the capital cost, both the pollution board consent and the loan can stall.
- Taking kiln fuel from a grinding unit's figures
A synthetic plant burns oil or gas at high temperature. Get a fuel figure per tonne from the kiln supplier and test it in the projections.
- Pricing from small-pack retail listings
Online prices for small bags run well above bulk ex-factory rates. Revenue should use what block makers and paint companies pay per tonne.
- Planning one grade for every buyer
Paint buyers want low sieve residue and soluble salts; block makers care more about price and colour strength. Plan the grade mix early.

Red Oxide Pigment project report: frequently asked questions
How much does it cost to set up a red oxide pigment plant in India?
A natural red oxide grinding unit can start at roughly ₹25–60 lakh, while a synthetic unit with a calcination kiln needs several crore. Our sample report models a 4.7 MT per day synthetic unit at ₹482 lakh, including land, building and working capital margin. These ranges are indicative; your project report costs the plant for your route, capacity and site.
What raw material is used to make red oxide pigment?
Synthetic red oxide is usually made from ferrous sulphate heptahydrate, called copperas, a by-product of steel pickling and titanium dioxide plants. In our sample report copperas is 76% of raw material cost, with hydrated lime for gas scrubbing and mill scale fines making up the rest. Natural red oxide is ground from hematite ore instead.
What is the difference between natural and synthetic red oxide?
Natural red oxide is mined hematite that is crushed, ground and classified, so its iron content and shade depend on the ore. Synthetic red oxide is made chemically, for example by roasting copperas, and gives a purer, more even shade. IS 44 treats them as separate grades: Grade 2 for synthetic and Grade 3 for natural red oxide.
Is red oxide pigment manufacturing profitable?
In our illustrative sample, a 4.7 MT per day synthetic unit earns a 20% return on investment in Year 3. It breaks even at about 37% of capacity and pays back in about 3.7 years. Real results depend on the copperas price you secure, kiln fuel cost, shade consistency and how much credit buyers take.
Can I get a PMEGP loan for a red oxide unit?
Only a small unit fits. PMEGP gives margin-money subsidy on manufacturing projects up to ₹50 lakh, which suits a natural red oxide grinding unit more than a kiln-based synthetic plant. Larger units usually take an MSME term loan, often with CGTMSE guarantee cover. Every lender asks for a project report with projections and DSCR.
Is the red oxide pigment project report PDF free, and can I use it for a loan?
The sample PDF 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 loan scheme.
