Abstract
Bei einem Verfahren zum Verwerten von eisen- und schwermetallhältigen, festen Reststoffen, gegebenenfalls unter Zugabe von, Eisenerz, wobei die Reststoffe zusammen mit kohlenstoffhältigen Reduktionsmittel sowie Sauerstoff in einen Schmelzzyklon (6) eingebracht, verwirbelt und gezündet werden, die Reststoff aufgeschmolzen werden, flüchtige Schwermetalle reduziert und verdampft werden und Eisenoxide reduziert werden, die Gase und die Schmelze aus dem Schmelzzyklon (6) gemeinsam in ein unmittelbar gekoppeltes Abscheidegafäss (7) überführt werden, in welchem eine Trennung von Schmelze und Gasen erfolgt, die verdampften Schwermetalle ausserhalb des Abscheidegefässes (7) aus den Gasen abgeschieden werden und die Schmelze in ein von Abscheidegefäss (7) getrenntes metallurgisches Gefäss (10) überführt wird, werden in das metallurgische Gefäss (10) einerseits Reduktionsmittel zugeführt, die Eisenoxide der Schmelze unter Bildung einer eisenarmen Schlacke zu Eisen reduziert und wird andererseits elektrische Energie zur zumindest teilweisen Deckung der Wärmeverlust und der Reduktionsenergie eingebracht, um die eisen- und schwermetallhältige Reststoffe zu 100% in verwertbare Produkte zu überführen.
