Abstract

Die Erfindung betrifft ein Verfahren zur Stoffgewinnung aus Schlacke, wobei der Stoff aus der noch flüssigen Schlacke gewonnen wird. Weiterhin schafft die Erfindung eine Vorrichtung zur Stoffgewinnung aus Schlacke, wobei Abscheideeinrichtungen und/oder Filtereinrichtungen zum Abscheiden bzw. Ausfiltern des Stoffes aus der noch flüssigen Schlacke vorgesehen sind. Gegenstand der Erfindung sind ferner die Verwendung von noch flüssiger Schlacke zur Stoffgewinnung daraus und die Verwendung von Abscheideeinrichtungen und/oder Filtereinrichtungen zum Abscheiden bzw. Ausfiltern eines Stoffes aus noch flüssiger Schlacke. Insbesondere handelt es sich um die Gewinnung von Aluminium und Salz aus einer Schlacke der Aluminium-Sekundärindustrie.
