Separation of valuable elements from steel making slag by chlorination
That is, Fe and Ti were completely separated from the slag by chlorination. Fe was volatilized below 1000 °C during carbon reduction/chlorination, and remarkable volatilization (40–90%) of Ti and P was also observed until 1000 °C. Therefore, the separation of each element using the volatilization kinetics of Fe, Ti, and P was difficultAbstract. This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures.
