Blast furnace slag can be processed into the following materials by various processes. In China, blast furnace slag is usually processed into water slag, slag gravel, expanded slag and slag beads.Water slag is the process of putting the hot-melt blast furnace slag into water for rapid cooling, which mainly includes slag pool water …
However, most ladle furnace slag already contains multiple heavy metals, such as Cr, Mn, V, W, and Mo. Research has shown that the leaching concentrations of some heavy metals in some types of ladle furnace slag exceed the leaching standard of inert waste (Loncnar et al., 2016). Thus, while stabilizing a heavy metal, new heavy …
