Iron and Steel Slag Utilization: A Comprehensive Analysis

Steel slag is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. In todays world, steel is a necessity; in 2016 alone, total crude steel production was over 1.6 billion tones.

Making Slag - an overview ScienceDirect Topics

2010-04-05  Iron making in the BF produces a slag that amounts to 20–40% of hot metal production. BF slag is considered environmentally unfriendly when fresh because it gives off sulfur dioxide and, in the presence of water, hydrogen sulfide and sulphoric acid are generated. These are at least a nuisance and at worst potentially dangerous.

Metal Recovery from Steelmaking Slag

An iron-rich concentrate containing 28% Fe, 3.9% Mn and an iron-lean tailing containing 7% Fe and 0.4% Mn. In order to make the iron-rich product recyclable, its grade needs to be improved. It was demonstrated that this is possible by grinding the roasted slag to a smaller particle size. Liquid-state oxidation yielded poor results, likely due to rapid cooling of slag following its

Effect of Charge Materials on Slag Formation in Ductile ...

The slag formed during Ductile Iron processing has many origins, some of them being inevitable. This is the case of the magnesium oxide and sulphide that evolve from the nodulization treatment. However, a significant amount of slag may also be generated by the charge materials used for the production of Ductile Iron castings.
