Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Vorbereitung sulfidischer Mischerze für die Gewinnung der in ihnen enthaltenen ' Metalle (z. B. Blei, Silber, Kupfer) in der Weise, daß der Zinkgehalt der Erze entfernt wird; das Verfahren kennzeichnet sich wesentlich durch die besondere Aufeinanderfolge mehrerer Einzelverfahren, wodurch eine raschere, stetige Arbeitsweise und eine bedeutendere Ausbeute der Erze möglich ist.The subject of the present invention is a method of preparation sulphidic mixed ores for the extraction of the metals contained in them (e.g. lead, Silver, copper) in such a way that the zinc content of the ores is removed; the procedure is essentially characterized by the special sequence of several individual processes, thereby a faster, steady operation and a more significant yield of ores is possible.
Der Erfindung gemäß wird das Erz zunächst langsam bei dunkler Rotglut geröstet, zu dem Zwecke, das in dem Erz enthaltene Zink in lösliche Sulfate überzuführen und den in dem Erz als Zinkoxyd verbleibenden Rückstand in nachfolgender Weise auszuziehen :According to the invention, the ore is first slowly roasted in a dark red heat, for the purpose of converting the zinc contained in the ore into soluble sulfates and to extract the residue remaining in the ore as zinc oxide in the following manner :
Das geröstete Erz wird vorteilhaft mitThe roasted ore is beneficial with
so kochendem Wasser ausgelaugt, um das Zinksulfat zu lösen. Nachdem sich die Lösung gesetzt hat, wird sie in Behälter ablaufen gelassen, in welchem sie mit einer Lösung von Calciumchlorid versetzt wird. Hierbei wird Calciumsulfat gebildet und niedergeschlagen, wobei gleichzeitig das gebildete Zinkchlorid in die Lösung geht. Letzteres wird von dem Niederschlag abgelassen und dient dazu, das in dem ausgelaugten Erz in Gestalt von Zinkoxyd verbliebene Zink aufzulösen. Zu dem Zweck ist es notwendig, daß das Erz in der Zinkchloridlösung bei deren Siedepunkt für eine Zeit digeriert wird, welche von der Art und der Menge des unter Behandlung stehenden Erzes und von der Stärke der Lösung abhängt. Bei richtigem Betriebe geht das in Lösung vorhandene Zinkchlorid in ein Oxychlorid von annähernd folgender Zusammensetzung über: Zn Cl2 2 Zn O, doch können diese Oxychloride selbstverständlich je nach Bedarf andere Zusammensetzungen erhalten. Zu dieser Lösung wird entweder gelöschter Kalk, Kalkkarbonat, Magnesia oder Ätznatron in genügender Menge zugesetzt, um vollkommene Zersetzung des Zinkchlorids herbeizuführen. Der so gebildete Zinkhydratoder Zinkkarbonatniederschlag wird dann endgültig ausgelaugt, um von dem Chlorid befreit zu werden und wird darauf nach bekannten Verfahren auf die Herstellung von Handelszink bearbeitet.so leached boiling water to dissolve the zinc sulfate. After the solution has settled, it is drained into a container in which it is mixed with a solution of calcium chloride. During this process, calcium sulfate is formed and precipitated, and the zinc chloride formed goes into solution at the same time. The latter is drained from the precipitate and serves to dissolve the zinc remaining in the leached ore in the form of zinc oxide. For this purpose it is necessary that the ore in the zinc chloride solution is digested at its boiling point for a time which depends on the type and amount of the ore under treatment and on the strength of the solution. When operated correctly, the zinc chloride present in solution changes into an oxychloride with approximately the following composition: Zn Cl 2 2 Zn O, but these oxychlorides can of course have other compositions as required. To this solution either slaked lime, lime carbonate, magnesia or caustic soda is added in sufficient quantities to bring about complete decomposition of the zinc chloride. The zinc hydrate or zinc carbonate precipitate thus formed is then finally leached in order to be freed from the chloride and is then processed by known methods to produce commercial zinc.
Nach Entfernung des Zinkgehaltes wird das Erz nach üblichen Schmelzverfahren auf die Gewinnung von Blei, Silber, Kupfer und anderer eventuell darin vorhandener Metalle behandelt. After the zinc content has been removed, the ore is poured onto the Extraction of lead, silver, copper and other metals that may be present in it.
