A method for treatment of metallurgical wastes i.e. slags, which are in liquid form by introducing water into the liquid slag thus causing it to cool at a slow rate so that the solidified slag contains a porous crystalline or utrified structure according to the rate of cooling, which structure is table at ambient temperature. Another object of the invention concerns an apparatus for treating solid metallurgical slags, comprising a continuous conveyor formed of moulds and means adapted to diffuse water into the liquid slag.
La présente invention concerne un procédé permettant de traiter des déchets métallurgiques, c'est-à-dire des scories, se présentant sous une forme liquide, par introduction d'eau dans la scorie liquide pour la refroidir lentement, de telle sorte que la scorie solidifiée contiennent une structure cristalline ou vitrifiée poreuse en fonction de la vitesse de refroidissement; ladite structure étant stable à température ambiante. Cette invention concerne également un dispositif permettant de traiter des scories métallurgiques solides, comprenant un tapis de transport en circuit fermé constitué de moules et de moyens conçus pour diffuser de l'eau à travers la scorie liquide.
