Low-Grade Iron Ore refers to iron ore with an iron (Fe) content typically below 58%. It contains higher levels of gangue minerals such as silica, alumina, phosphorus, and moisture.
Despite lower iron concentration, low-grade iron ore remains strategically important due to its abundance, lower mining cost, and suitability for beneficiation, agglomeration, and blending.
Available Forms
| Form | Description |
|---|---|
| Run-of-Mine (ROM) | Raw ore extracted from mine |
| Lumps | Sized ore for beneficiation or blending |
| Fines | Crushed ore for upgrading processes |
| Concentrates | Beneficiated ore with improved Fe |
| Pellet Feed | Upgraded fines for pelletization |
| Sinter Feed | Treated fines for sinter plants |
Applications
Beneficiation plants (upgrading to higher Fe content)
Sintering and pelletization units
Blended feedstock for blast furnaces
Direct Reduced Iron (after upgrading)
Cement industry (iron correction material)
Export of upgraded concentrates
Advantages
✔ Abundant and widely available
✔ Lower raw material cost
✔ Supports long-term resource sustainability
✔ Suitable for beneficiation and value addition
✔ Enables strategic blending with high-grade ores
Key Characteristics
| Parameter | Description |
|---|---|
| Iron Content | Below 58% |
| Impurities | Higher silica and alumina |
| Moisture / LOI | Moderate to high (deposit dependent) |
| Processing Requirement | Beneficiation required |
| Untreated Furnace Performance | Lower efficiency |
Why Choose Low-Grade Iron Ore?
Low-grade iron ore is chosen as a cost-effective and abundant raw material source that can be upgraded using modern beneficiation technologies.
It ensures continuity of iron ore supply, supports large-scale steel production, and enables sustainable utilization of iron resources, especially in regions with limited high-grade reserves.
