Iron and Steel Slag Utilization: A Comprehensive Analysis

2019-8-21  3.2 Crushing and Magnetic Separation 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. Figure 3 showcases the multiple times magnetic separation process takes place to increase the metal iron
