Abstract
A pyrometallurgic process for the treatment of post-steelwork residues, comprises the following phases: preparing a furnace () of the electric type, suitable for the introduction of the residues; preparing the residues, for example in a hopper with the possibility of mixing with additives and reaction elements; introducing the residues, together with suitable additives and chemical reagents, into the furnace (); introducing directly into the slag, by means of lances (), additives, flushing and reaction elements to correct the composition of the slag (); reacting the residues with the slag () to obtain: a) separation of the liquid metallic phases which are added to the metal bath () to form a sellable liquid metal; b) separation of the metallic volatile elements in vapour phase which, when transferred to the free zone of the furnace () recombine with the oxygen for the formation of oxides and consequently of powder.
