Abstract
During the production of steel by a converter process, a slag is produced and stored at slag depots, thus causing serious difficulties through pollution and space requirements. A converter slag is a compact and abrasive raw material containing CaO and Fe. The investigations showed that a multi—stage crushing, classifying and magnetic separation operations influence successful steel recovering from slag, while slag itself is converted into a high—grade fluxing agent which can be used in production of sinter and raw iron. Also, positive economic effects are achieved through a partial substitution of more expensive limestone and a full substitution of Mn—ore and dolomite.
