Steel Slag
Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction (Sheen et al., 2013; Manso et al., 2004).

— In ilmenite smelters, titania slag is tapped at 1650–1700°C, while iron metal is tapped at about 1500°C, i.e., 150–200°C lower than the slag temperature. Fluxes cannot be used to decrease the slag melting temperature because impurities like MgO, CaO, and SiO 2 (from the flux) can have a negative impact on the slag quality, especially if ...
