Description

Verfahren zum Raffinieren von Metallen, insbesondere von Kupfer Die Erfindung betrifft ein Verfahren zum Raffinieren von Metallen, im besonderen Kupfer, und zwar bezweckt und gestattet es die Entfernung solcher metallischen Verunreinigungen aus dem Metallbade, die zum Chlor eine größere Verwandtschaft haben als das zu reinigende Metall, z. B. die Entfernung von Wismut aus Kupfer.Process for refining metals, especially copper Die The invention relates to a method for refining metals, in particular copper, namely, it aims and allows the removal of such metallic impurities from the metal bath, which are more closely related to chlorine than the one to be purified Metal, e.g. B. the removal of bismuth from copper.

Das Verfahren der Erfindung beruht auf der Maßnahme, die Verunreinigung in Chloride überzuführen, die aus dem Bade leicht entfernbar sind.The method of the invention relies on the measure of contamination to be converted into chlorides, which can be easily removed from the bath.

Zu diesem Zweck ist schon vorgeschlagen worden, gasförmiges Chlor in Metallbäder einzuleiten. Weiterhin hat man auch schon versucht, verschiedene Chlorverbindungen zu diesem Zwecke zu verwenden.For this purpose it has already been proposed to use gaseous chlorine to be introduced into metal baths. Furthermore, one has already tried different To use chlorine compounds for this purpose.

Erfindungsgemäß erfolgt nun die überführung der Verunreinigungen in Chloride in der Weise, daß in das zu raffinierende geschmolzene Metallbad Chlorverbindungen, die die Verunreinigungen in Chloride überführen sollen, im Gemisch mit kleinstückiger Kieselsäure, Sand oder einem sonst hochkieselsäurelialtigen Material eingeführt werden. Die im Bade vor sich gehende Umsetzung wird dann schematisch etwa nach folgender Formel erfolgen, in welcher Me das Metall bedeutet, das als Verunreinigung entfernt werden soll: aNaCl-;-bSiO.,-;-cMe0=-. dNa.Si0.-'--eMeCl..According to the invention, the impurities are now converted into Chlorides in such a way that chlorine compounds, which are supposed to convert the impurities into chlorides, mixed with small pieces Silica, sand or some other highly silicic acid material introduced will. The conversion going on in the bath is then shown schematically as follows Formula in which Me means the metal that removes as an impurity should be: aNaCl -; - bSiO., -; - cMe0 = -. dNa.Si0.-'-- eMeCl ..
