Large magnetite iron ore reserves estimated at approximately 800 million tonnes have been identified in Andhra Pradesh’s Prakasam district, marking one of the most significant mineral discoveries in the region in recent years.
Preliminary assessments indicate iron (Fe) content ranging between 18% and 25%, classifying the deposit as low-to-medium grade magnetite. JSW Steel holds exploration rights for the block and is currently conducting pilot studies to evaluate commercial viability and beneficiation potential.
Scale of the Discovery in National Context
India’s total iron ore reserves are estimated at over 33 billion tonnes, of which magnetite accounts for nearly 10–11 billion tonnes, primarily located in Karnataka, Andhra Pradesh, Rajasthan, and Kerala.
An 800 million tonne deposit would represent:
-
Around 2–3% of India’s total iron ore reserves
-
Nearly 7–8% of the country’s known magnetite reserves
While hematite ore dominates India’s production mix due to its higher natural iron content (typically 58–63% Fe), magnetite deposits have historically remained underutilized because of beneficiation requirements and higher processing costs.
The Prakasam discovery therefore adds strategic long-term potential rather than immediate high-grade output.
Grade Considerations and Beneficiation Requirements
The reported Fe content of 18–25% is significantly below the typical commercial threshold for direct blast furnace usage. However, magnetite ore can be upgraded through beneficiation processes such as:
-
Crushing and grinding
-
Magnetic separation
-
Concentration and pelletisation
With beneficiation, Fe content can be upgraded to 62–65% or higher, making it suitable for pellet production and direct reduced iron (DRI) applications.
India’s pellet production capacity currently exceeds 120 million tonnes per annum, though utilization varies based on export demand and domestic steel production. Additional magnetite feedstock could support pellet plant expansion, particularly in southern India.
Regional Impact and Logistics Advantage
Andhra Pradesh’s proximity to coastal infrastructure enhances the commercial attractiveness of the discovery.
Prakasam district is strategically located with access to:
-
Krishnapatnam Port
-
Chennai and Ennore ports
-
Rail connectivity to Karnataka and Tamil Nadu steel clusters
Southern India currently accounts for a significant share of electric arc furnace (EAF) and DRI-based steelmaking capacity. A steady supply of upgraded magnetite concentrate could reduce dependence on inter-state ore movement from Odisha and Chhattisgarh.
India’s Steel Demand Outlook and Raw Material Implications
India produced approximately 140 million tonnes of crude steel in FY2023-24 and is targeting 300 million tonnes of capacity by 2030 under the National Steel Policy.
Iron ore demand is projected to rise proportionally, with consumption likely to exceed 230–250 million tonnes annually over the next decade.
In this context, long-term magnetite development becomes strategically important for:
-
Securing raw material supply
-
Reducing import dependence
-
Supporting pellet and DRI expansion
While the Prakasam deposit may not immediately alter supply dynamics, it strengthens resource security in southern India.
Investment and Development Timeline
JSW Steel’s ongoing pilot studies will determine:
-
Ore beneficiation feasibility
-
Capital expenditure requirements
-
Environmental and regulatory clearances
-
Infrastructure development costs
Magnetite projects typically require higher initial capital due to processing infrastructure. Industry benchmarks suggest beneficiation and pellet integration projects can involve investments ranging from ₹1,500–3,000 crore, depending on scale.
Commercial production timelines will depend on regulatory approvals, land acquisition, and infrastructure readiness.
Market Implications
Short-term iron ore pricing is unlikely to be affected by the discovery, as commercial production would require multi-year development.
However, over the medium-to-long term, the deposit could:
-
Improve southern India’s raw material self-sufficiency
-
Support pelletisation growth
-
Provide feedstock flexibility for DRI-based steelmakers
-
Strengthen India’s overall iron ore reserve base
If successfully upgraded and integrated into the value chain, the 800 million tonne deposit could become a structurally important supply source for the region.
Metalsbuy Market Pulse Assessment
The Prakasam magnetite discovery is significant in scale but strategic in nature rather than immediately supply-disruptive.
Key takeaways:
-
800 million tonnes adds meaningful reserve depth
-
18–25% Fe requires beneficiation for commercial use
-
Supports long-term steel capacity expansion targets
-
Enhances southern India’s resource positioning
The development outcome will depend on beneficiation economics and steel demand growth. If aligned with India’s 2030 steel capacity roadmap, the deposit could play a meaningful role in strengthening raw material security.
