Green steel from red mud through climate-neutral hydrogen plasma reduction

M. Jovičević-klug, I. R. S. Filho, et al.

Discover a groundbreaking method by Matic Jovičević-Klug, Isnaldi R. Souza Filho, Hauke Springer, Christian Adam, and Dierk Raabe that transforms red mud, a waste of alumina production, into green steel using fossil-free hydrogen-plasma reduction. This innovative process not only aids in sustainable red mud disposal but also significantly reduces CO2 emissions associated with steel production.

Abstract
This paper presents a novel method for converting red mud, a waste product of alumina production, into green steel using fossil-free hydrogen-plasma-based reduction. The process involves rapid liquid-state reduction, chemical partitioning, and density/viscosity-driven separation to extract iron. This approach offers a sustainable solution for red mud disposal and contributes to mitigating steel-related CO2 emissions.
