  Iron and Steel Slag Utilization: A Comprehensive Analysis

  2019821 · 2.1 Iron/steel slag production Properties of steel slag depends on the type or gray of steel being produced and the furnace used. It is a byproduct of molten iron processing and originates from the gangue in the mineral raw materials such as iron ore, coal, and limestone as well as those in the flux used at steel refining processes to remove …

  The Composition and Performance of Iron Ore Tailings in Steel Slag ...

  Iron ore tailings (IOTs) are byproducts of the iron mining industry that have gained significant attention in recent years due to their potential for comprehensive utilization. This study investigates how blending steel slag with IOTs (a siliceous raw material) instead of lime (a calcareous raw material) affects slurry foaming properties, mechanical properties, and …

  Sulphur removal in ironmaking and oxygen steelmaking

  2017322 · The SM ladle treatment processes are comparable for both BF-BOF and EAF steelmaking. However, sulphur removal is less of an issue in the EAF process, since its raw materials (scrap, direct reduced iron) contain less sulphur than the raw materials of the BF-BOF process (iron ore, coke and coal) 1, 4.
