Iron Recovery & Valorization

Turning iron-rich residues into clean feedstock for low-carbon steelmaking

PROBLEM: Iron Locked in Waste, Not in Production

Iron is abundant, but in mining and metallurgy it’s often discarded within tailings and mixed feeds, creating massive storage liabilities and lost value. 

At the same time, steelmakers need high purity iron ore for low-carbon steel production using the modern DRI method - yet face a looming global shortage.

TENSION: A Global Shortage Meets a Carbon Challenge

Steel contributes ~7% of global CO₂ emissions. 

As the industry transitions toward low-emission production, DR-grade iron ore demand is projected to outpace supply by 2–3x by 2030. 

Market outlook: 

  • US$31.2B DR-grade market (2022); 8.6% CAGR (2023–2032) 

  • Forecasted 160–200 Mtpy demand vs. 40–100 Mtpy supply

SOLUTION: Recovering High-Purity Iron from Residues

GEOMEGA’s technology selectively recovers high-purity iron products from mining tailings and industrial waste — delivering feedstock of DR-grade iron ore.

The process operates in a closed-loop, low-effluent design that also allows to capture valuable secondary metals such as Ni, Co, and REE, if present.  

Key Advantages 

  • 95% Fe recovery, >98% Fe₂O₃ purity 

  • Converts waste iron to DR-grade iron oxide 

  • 60% lower CO₂ footprint vs. conventional refining 

  • Polymetallic recovery in one circular process

PROOF: Pilot Validation

• Bench-scale testwork confirmed economic recovery from bauxite residue (red mud), REE magnet recycling and other iron rich tailings

• Successful piloting at GEOMEGA’s Boucherville facility (TRL 6–7)

• Demonstration scale plant being built for magnet recycling application

• Ongoing engineering with Rio Tinto for an on-site demonstration plant from bauxite residue

PAYOFF: Closing the Iron Loop

Recover iron. Reduce waste. Enable low-carbon steelmaking. 
Circular metallurgy isn’t a dream — it’s already in production. 

Operational: Recover high-purity Fe with near-zero waste; reduce storage liabilities; lower OPEX via closed loop; deploy on-site. 

Strategic: Supply DRI market; co-metal revenues; stronger ESG; license or co-develop plants.
