Abstract (en)

[origin: EP0722777A1] The method involves raw slag being separated into at least two fractions and the first fraction has a particle size of up to 80 mm, pref. 32 mm in a first phase. The screen overflow from the first phase is supplied to the wet slag separator (4). The through-fall through the screen and through the fire rack is sent to a second screen phase (5) to separate the fine material. The screen overflow from the second phase is mechanically pulverised after sorting out the metal and inert materials and the through-fall from the second phase is sent to a melting furnace (7) for separate processing. A third screen phase (8) can be included.
