Toward Fossil‐Free Steelmaking: Overview of Physiochemical Properties of Hydrochar and Its Application in Blast Furnace and Electric Arc Furnace Processes

cScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.

Extraction of Vanadium from CaO–SiO2–MgO–Al2O3 Slags Based on Vaporization of Vanadium Pentoxide

steel research international, Volume 96, Issue 8, August 2025.
In the present article, fundamental reaction mechanisms for the extraction of vanadium from CaO–SiO2–Al2O3 slags based on vaporization of V2O5 are investigated. Several parameters influencing the vanadium extraction are analyzed. The results make it possible to develop innovative methods for extracting vanadium from slags.

Effect of Fe2O3 Content and Acid on the Leaching Behavior of Phosphorus from Dephosphorization Slag

, 2021
Dephosphorization slag contains considerable quantities of valuable components, such as P2O5 and FeOx. To recover P from dephosphorization slag, selective leaching has been adopted to separate the P-concentrating mineral phase.

Phosphorus Partition in an Industrial Basic Oxygen Furnace Process in Ukraine

steel research international, Volume 96, Issue 8, August 2025.
Phosphorus partition data from Ukrainian steel plants are analyzed, focusing on parameters like basicity, optical basicity, tapping temperature, and slag contents of FeO, MgO, and Al2O3. The analysis shows that phosphorus partition decreases with higher tapping temperatures and increases with optical basicity.
