PREPARATION METHOD FOR STAINLESS STEEL SLAGS AND STEELWORKS SLAGS FOR RECOVERY OF METAL |
摘要 |
<p>The invention relates to a preparation method for stainless steel slags and modified steelmaking slags for recovering metal. In order to create a dry-operating preparation method that ensures low-wear and energy-efficient comminution and deagglomeration of stainless steel slags and modified steelmaking slags and highly precise separation of a metal fraction and a silicate fraction and that can be variably designed regarding the different slag compositions and different requirements for the quality of the metal fraction and the at least one silicate fraction, a roller mill is used at least for the comminution. The slags are fed at a feed grain size up to approximately 150 mm. The use of an air-swept roller mill in which the comminution and deagglomeration, if necessary drying, and at the same time separation into a substantially mineral-free metal fraction and a nearly metal-free silicate fraction are combined, is advantageous. If an overflow roller mill is used, the metal fraction and the silicate fraction are separated in an external separating device.</p> |
