Slag recycling - recovery

In the iron ore-based process, pig iron is produced from oxidic iron ores in a blast furnace. In an LD oxygen converter the molten pig iron is then processed together with steel scrap into crude steel. In the purely scrap-based production variant, the raw steel is produced by recycling steel scrap in an electric arc furnace.

Iron and Steel Slag Utilization: A Comprehensive Analysis

2019-8-21  Steelmaking slag includes 10% to 40 % iron metal which can be separated for different purposes. Iron can be recovered and used as a substitute for scrap iron, iron can be segregated for effective use of slag for applications where iron would act as an impurity. For these reasons the slag is crushed and iron is recovered by magnetic separation.
