 Red mud, also known as bauxite residue, is a highly alkaline (pH 10-13) waste generated during alumina production via the Bayer process. 

Globally, approximately 170 million tonnes of red mud are produced annually, with India contributing around 5 million tonnes per year.  

Odisha, being a hub of alumina production, faces significant environmental risks due to red mud storage, including soil and water contamination .

Red mud contains valuable metals, including iron oxide (56.7%), rare earth elements (REEs), alumina, and titanium. The estimated value locked in global red mud reserves is approximately $30 billion, with Odisha's high-iron red mud representing an untapped resource .

Project Objectives

· Primary Objective: 

Demonstrate the technical and economic feasibility of extracting iron oxide from red mud using a chemical-free process.

· Secondary Objectives:

· Achieve 95% extraction efficiency for iron oxide.

· Process 500 tons per day of red mud.

· Ensure zero waste discharge through residue utilization.

· Contribute to environmental sustainability by reducing red mud stockpiles.

Project Overview

· Feedstock: 10,000 tpd red mud (bauxite residue) sourced from alumina refineries

· Target Outputs:

· Primary: 5,000 tpdiron oxide (Fe₂O₃ ≥99%, battery-grade)

· Secondary: REE concentrate (Ce, La, Nd, Sc, Y), titanium dioxide, aluminum oxide

· Technology Basis: Patented hydrometallurgical process enabling selective metal extraction at low temperatures (70–90°C) with reagent recycling .

· Scale Justification: Aligns with global red mud generation of 177 million tons annually (2023) .

Green Steel Production from Red Mud

Green steel production focuses on *replacing carbon reductants with hydrogen*, eliminating CO₂ emissions. Two primary methods have emerged:

*Hydrogen Plasma Reduction*

- *Process: Red mud is melted in an **electric arc furnace (EAF)* using a hydrogen-argon plasma (10% H₂). Iron oxides are reduced to liquid iron within *10 minutes, achieving*~70% metallization**. 

Outputs: 

- *High-purity iron* (directly usable for steelmaking).

- *Neutralized slag* (pH drops from 10.5 to 7.5), forming a glassy material suitable for construction.

- Advantages: 

- No preprocessing (e.g., pelletizing) required.

- Heavy metals are immobilized in the slag, preventing leaching.

- *CO₂ savings: Using green hydrogen could save **1.5 billion tonnes of CO₂* if applied to all stockpiled red mud.

Thermite Production from Red Mud

Thermite requires a mixture of *metallic aluminum* and *iron oxide* to drive the exothermic reaction: 

$$ \ce{2Al + Fe2O3 -> 2Fe + Al2O3 + \text{heat}} $$ 

Red mud's composition makes it a candidate, but challenges exist:

*Feasibility and Challenges*

- *Alumina Recovery: Alkaline leaching of reduced red mud pellets extracts **62–87% alumina*, which could be processed into aluminum powder.

- *Iron Oxide Enrichment: Magnetic separation post-reduction yields iron concentrate (33–52% Fe*), but purity is insufficient for thermite.

- *Energy Intensity*: Producing aluminum powder from recovered alumina requires electrolysis, offsetting thermite's economic benefits.

*Alternative Approach*

- *Direct Use of Reduced Red Mud*: Partially reduced iron (e.g., sponge iron) could be mixed with recovered aluminum powder. However, impurities (e.g., TiO₂, SiO₂) may inhibit the reaction.
