Description

Verfahren zur Gewinnung von Zinn Das Hauptpatent betrifft ein Verfahren zur Gewinnung von Zinn aus gangartarmem zinnhaltigem Gut, wie Erzen, Hüttenoxyden o. dgl. Stoffen, das auch noch einen Gehalt an Zink und anderen Metallen haben kann. Es besteht darin, daß das Gut mit Reduktionsmittel gemischt im Zinkmuffelofen oder Elektroofen oder einer stehenden Muffel erhitzt wird und daß dabei durch einen Zuschlag, wie Soda, Wasserglas o. dgl. Fluß-oder Schutzmittel, das in der Beschickung verbleibende reduzierte Zinn in grobkörnige Form übergeführt wird, während das gegebenenfalls vorhandene Zink in bekannter Weise abdestilliert.Process for the extraction of tin The main patent relates to a process for the extraction of tin from low-gait tin-containing goods, such as ores, iron and steel oxides or the like. Substances that can also contain zinc and other metals. It consists in the fact that the material is mixed with reducing agent in a zinc muffle furnace or Electric furnace or a standing muffle is heated and that by a surcharge, such as soda, water glass or the like. Flux or protective agent, that remaining in the charge reduced tin is converted into coarse-grained form, while that optionally existing zinc distilled off in a known manner.

Es wurde nun gefunden, daB die Verflüch=-tigung von Zinn oder ähnlichen schwerer flüchtigen Metallen sowie die mechanischen Verluste an diesen Metallen noch wesentlich dadurch herabgesetzt werden können, daß die Oxyde des Zinns, Bleis oder ähnlicher schwerer flüchtiger Metalle fester an die unlialtigen Teile der Beschickung gebunden werden, und zwar dadurch, daß die Beschikkung mit Stoffen wie Soda, Wasserglas oder Mischungen dieser Stoffe angeteigt oder mit Verwendung dieser und ähnlicher Zuschläge gesintert in den Gefäßofen gebracht wird. Im Falle des Sinterns ist es für den Erfolg des Verfahrens einerlei, ob der Zusatz von Soda o. dgl. schon vor dem Sintern oder erst nach dem Sintern und vor Einbringen in den Reduktionsofen dem Gut beigemischt wird.It has now been found that the volatilization of tin or the like less volatile metals as well as the mechanical losses of these metals can still be substantially reduced by the fact that the oxides of tin and lead or similar less volatile metals more firmly to the unwanted parts of the charge be bound by the fact that the loading with substances such as soda, water glass or mixtures of these substances made into a paste or with the use of these and the like Sintered aggregates are brought into the vessel furnace. In the case of sintering, it is For the success of the process it does not matter whether the addition of soda or the like has already been done the sintering or only after the sintering and before introduction into the reduction furnace is added to the good.

An sich ist es bekannt, z. B. Zinkmuffeln mit gesintertem Gut zu beschicken, um die Ladedichte insbesondere von fein verteiltem Gut zu erhöhen. Eine Verdichtung der Beschickung kann bei dem Verfahren gemäß der Erfindung natürlich auch eintreten. Darüber hinaus wirkt es aber durch Unterdrükkung der Verflüchtigung des Zinns und der anderen schwerer flüchtigen Metalle dahin, daß sich einerseits eine größere Ausbeute und geringere Verluste an den in der Beschickung zurückbleibenden reduzierten Metallen und andererseits, falls Zink in der Beschickung vorhanden ist, ein reineres abdestilliertes Zink ergeben.It is known per se, e.g. B. to feed zinc muffles with sintered goods, in order to increase the loading density, especially of finely divided goods. A compression loading can of course also occur in the method according to the invention. In addition, it works by suppressing the volatilization of the tin and of the other less volatile metals to the point that on the one hand there is a larger Yield and lower losses of the reduced ones left in the feed Metals and, on the other hand, if zinc is present in the charge, a purer one result in distilled zinc.

Die Erfindung ist in der gleichen Weise wie das Verfahren nach dem Hauptpatent auch anwendbar, wenn die reduzierte $eschickung neben Zinn andere Metalle, wie Blei, Antimon, Wismut oder mehrere dieser Metalle, enthält. Auch ist es nicht erforderlich, daß die Beschickung in besonderem Mäße gangartarm ist.The invention is in the same way as the method according to The main patent is also applicable if the reduced shipment contains other metals in addition to tin, how Lead, antimony, bismuth or more of these metals. It is also not necessary for the loading to be particularly low in gait is.
