Synergistic mechanisms of steelmaking slag coupled with carbide slag for CO2 mineralization
International Journal of Greenhouse Gas Control, 2021Mineralization is an important means for emission reduction and utilization of CO2. Industrial calcium-based by-products such as steelmaking slag and carbide slag are often used as inexpensive mineralizers for CO2.

Current Opinion in Green and Sustainable Chemistry, 2020
The steelmaking industry relies on fossil fuel sources such as coal and coke (around 70% of the total energy required) to supply the increasing demand for steel (nearly 1752 million tones for 2020), which has an extreme impact on the environment, releasing almost 27% of the global CO2 emissions.

Ironmaking & Steelmaking: Processes, Products and Applications
Direct reduced iron (DRI)-based steelmaking requires high-grade iron ore (Fe > 65 wt-%). However, a swift decline in ore grade has forced steelmakers to use lower-grade ores for DRI making, creating challenges in subsequent processes dealing with high ...
