The invention can be used for reprocessing derivatives of the metallurgical industry, in particular metallurgical waste slags for recovering metal therefrom. The inventive method consists in crushing and fractional sizing the slags by means of a sizing device. The novelty of the invention lies in that the crushing is carried by rolling said slag in a roller device, and that the rolling and the fractional sizing are carried out by steps successively reducing the space between the rolls of the roller device, that the roller device is embodied in the form of a roller mill or a drum mill, that the sizing device is embodied in the form of a vibratory screen and a diverter drum. Said invention makes it possible to extract stainless steel and other metal of any fraction from the slag, thereby increasing the degree of metal recovery from the waste metallurgical slags. |
