Metal Recovery from BOF Steel Slag by Carbo-thermic

Abstract. BOF steel slag is a main by-product in steelmaking. The valorization of BOF slag is good for the industry and the environment. In the present study, the carbo-thermic reduction of BOF slag has been investigated, the reduction of Fe and P containing phases (i. e. oxide and compounds) is discussed, and the effects of Al 2 O 3 additions on the reduction process are described.
