| The invention relates to a preparation method for stainless steel slags and modified steelworks slags for recovery of metal. In order to create a dry preparation method which guarantees a low wear and energy efficient comminution and de-agglomeration of stainless steel slags and modified steelworks slags as well as a selective separation of a metal fraction and a silicate fraction and which can be variable in relation to the different slag compositions and different requirements upon 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 supplied with a feed grain size of up to approximately 150 mm. The use of an air swept roller mill is advantageous, in which the comminution and de-agglomeration, if necessary drying, and at the same time a separation into an extensively mineral-free metal fraction and a virtually metal-free silicate fraction are brought together. When using an overflow roller mill the separation of the metal fraction and the silicate fraction takes place in an external classifier. | ||||||
