Treatments and Recycling of Metallurgical Slags

2018-11-7  Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other byproducts. In this chapter, techniques for the treatment and recycling of metallurgical slags are described. Metallurgical slags are considered secondary raw materials and are used or added during the process to improve steelmaking practice.

Recycling Effects of Residual Slag after Magnetic

If most of the phosphorus can be removed from the slag, the residual slag will comprise FeO–CaO–SiO 2 –MnO–MgO with less P 2 O 5, and thus may be recycled to iron- and steel-making processes, such as sintering, hot-metal desiliconization, and hot-metal dephosphorization processes. In the present work, the recycling effect of subjecting
