Reduction Behavior of Hematite‐Biowaste Composite Pellets at Melting Temperature

steel research international, Volume 95, Issue 2, February 2024.
The ferrous industry faces challenges such as greenhouse gas emissions and heavy reliance on fossil fuels. To promote sustainability, this study explores the use of biowaste, specifically spent coffee grounds, for reducing hematite. Composite pellets of hematite and transformed‐spent coffee grounds are directly heat‐treated at 1550 °C, considering the ...
