Description
Verfahren zur Rückgewinnung Jes-.Dletällgehaltes aus Metallaschen. leer Metallgehalt von Aschen, wie sie. beim Verzinnen, Verzinken oder Verbleien von-Metallen erzeugt werden, wurde bisher in der' Weise wiedergewonnen, daß die betreffenden Metalle durch Erhitzen der erkalteten Aschen aus diesen ausgeschmolzen wurden. Im Gegensatz hierzu besteht der Gegenstand der Erfindung darin, daß.:die Metallaschen Ynicht von neuem erhitzt, sönelerri irn heißen Zustande in kaltes Wasser geworfen werden. Hierdurch wird erreicht, daß das in der heißen Asche befindliche flüssige Metallunter gleichzeitiger Befreiung von den -verunreinigenden Bestandteilen zu einzelnen Kügelchen erstarrt, die von den Verunreinigungen leicht zu trennen sind. Außerdem werden die Kosten für die bislang übliche erneute Erhitzung der Metallaschen erspart. Idas Abschrecken von Stoffen mit kaltem Wasser ist an sich nicht neu. Doch handelt es sich bei dem bekannten Verfahren um das Ablöschen von gerösteten Gemengen von Erzen, .wie Schwefelkies wnd Zinkblende, oder urn das Granulieren von Hochofenschlacke.Process for the recovery of grains from metal ashes. empty metal content of ashes like them. when tinning, galvanizing or lead-plating produced by metals has hitherto been recovered in such a way that the The metals concerned are melted out of them by heating the cooled ashes became. In contrast, the object of the invention is that.: The Metal ashes are not reheated, but should be put in cold water when they are hot to be thrown. This ensures that what is in the hot ash liquid metal with simultaneous removal of the contaminating components solidifies into individual globules, which are easy to separate from the impurities are. In addition, the cost of reheating the metal ashes, which has been customary up to now saved. Quenching fabrics with cold water is not in itself new. Indeed The known method involves the extinguishing of roasted mixtures of ores, such as pyrites and zinc blende, or the granulation of blast furnace slag.
