  Verfahren zur Extraktion des Kupfers und anderer Metalle aus Kiesabbränden. 



   Vorliegende Erfindung betrifft ein Verfahren zur Extraktion des Kupfers und der übrigen in Schwefelkiesabbränden (Rückstände von der Röstung der Eisenkiese) enthaltenen Metalle, wie Blei, Zink usw., aus diesen Abbränden durch Behandeln dieser letzteren mit Chlor im   Eutstehungszustande   auf nassem Wege und bei   verhältnismässig   niedriger Tem-   peratur.   Dieses Vorfahren besitzt gegenüber   den bisher gebräuchlichen   den Vorteil, eine vollständigere und mit geringeren Kosten verbundene Extraktion des Kupfers, sowie eine sich auf nahezu die Gesamtmenge der übrigen vorhandenen Metalle, wie Blei, Zink usw.,   erstreckende   Extraktion zu ermöglichen,

   während   bei des bisherigen Verfahren diese     anderen Metalle   in den Abbränden verbleiben, was bei Verwendung der letzteren im Eisen-   iiüttenwesen   von Nachteil ist. Insbesondere gegenüber dem   bekannten Verfahren der He-

  Process for the extraction of copper and other metals from gravel burns.



   The present invention relates to a process for the extraction of copper and the other metals contained in pebbles (residues from the roasting of iron pebbles), such as lead, zinc, etc., from these burns by treating the latter with chlorine in the state of formation on a wet route and at a relatively lower level Temperature. This ancestor has the advantage over the previously used ones of allowing a more complete and less costly extraction of the copper, as well as an extraction that extends to almost the entire amount of the other metals present, such as lead, zinc, etc.

   while in the previous process these other metals remain in the burns, which is a disadvantage when the latter is used in the iron and steel industry. Especially compared to the known method of he-
