Sustainable iron recovery from tailings via green reduction technology represents a promising pathway to transform mining and metallurgical waste into valuable resources while minimizing environmental footprints. Tailings, often considered as hazardous by-products, contain significant quantities of iron that can be recovered through innovative eco-friendly reduction processes. Unlike conventional methods that rely on high energy input and carbon-intensive agents, green reduction technologies utilize renewable energy, biomass-derived reductants, or hydrogen-based approaches to extract iron efficiently. This strategy not only reduces greenhouse gas emissions but also mitigates the risks of soil and water contamination caused by tailings storage. By converting waste into a resource, the approach contributes to the circular economy, enhances raw material security, and promotes sustainable mining practices. Moreover, large-scale adoption of such technologies could help industries achieve carbon neutrality targets while reducing reliance on virgin iron ore extraction, thus preserving natural ecosystems and reducing land degradation.
