Moreover, AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not important. Perhaps the most important characteristic of AOD slag is that it contains a high amount of Cr (2.5–4.3%) and some Ni (0.2–0.45%).
The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.Recovery of Metal from Slag in the Ferroalloy Industry,Recovery of Metal from Slag in the Ferroalloy Industry Effect of Slag Foaming and Lime Injection in Electric Arc Furnace on Steel Quality.
