EMI1.1
Es ist bekannt, gemischte Erze durch Schmelzen mit Chlorzink oder seinen Doppelsalzen und Ausfällen von Silber und Blei durch Zink in der Weise zu verarbeiten, dass der Zinkzusatz, sei es in einem Kessel oder einer Reihe hintereinandergeschalteter Kessel, in solcher Menge zugegeben wird, dass alles vorhandene Silber und Blei gefällt wird.
Erfahrungsgemäss kommt man hiebei nicht mit einem dem Blei uud Silber äquivalenten Zinkzusatz aus, da die in der Chlorzinkschmolze gelüsten Eisensalze durch Zink ebenfalls zu Metall reduziert werden. Ausserdem bildet sich hiedurch ein aus Blei, Zink und Eisen bestehender Schlicker, welcher einerseits einen weiteren Verlust von Zink darstellt und andererseits durch seine breiartige Konsistenz den Prozess stört.
Nach vorliegender Erfindung wird nun das eingangs erwähnte Verfahren dahin abgeändert, dati man nicht alles in der Schmelze vorhandene Chlorhlei dort mit Zink ausfällt, sondern einen Teil des Chlorbleies ungefällt darin lässt und die Gewinnung des rest- lichen Bleies in wässeriger Lösung vornimmt. Bei gewissen Erzen, z.
B. solchen mit besonders hohem Eisen-und geringem Bleigehalt, ist es sogar zweckmässig. \on der Fiillung des Bleies in der Schmelze ganz abzusehen und das Blei ausschliesslich aub wasseriger Lösung zu gewinnen. t) a die Reduktion des Eisens durch Zink nur in einer an Bleichlorid armen Schmelze erfolgt, wird nach dem vorliegenden Verfahren diese Reaktion ausgeschaltet und
EMI1.2
Zwecks Gewinnung des Bleies aus wässeriger Lösung wird die feurignüssige Schmelze in weicher das gesamte Erz nebst Gangart suspendiert ist und welche kein Silber und nur geringe Mengen Blei enthält, in Waster gegossen. wober sofortige Lösung durch Granulation der Schmelze und Erhitzung des Wassers eintritt. In dieser heissen und chlorzinkhaltigen Flüssigkeit bleibt das Bleichlorid gelöst und gestattet so die verlustlosn Trennung der festen Bestandteile von der Flüssigkeit. Aus letzterer wird entweder das bleichlorid partiell

EMI1.1
It is known to process mixed ores by smelting with zinc chloride or its double salts and precipitating silver and lead by zinc in such a way that the zinc additive, whether in a boiler or a series of boilers connected in series, is added in such an amount that everything existing silver and lead is precipitated.
Experience has shown that a zinc additive equivalent to lead and silver is not sufficient, since the iron salts desired in the chlorine-zinc melt are also reduced to metal by zinc. In addition, a slip consisting of lead, zinc and iron is formed, which on the one hand represents a further loss of zinc and on the other hand disrupts the process due to its pulpy consistency.
According to the present invention, the method mentioned at the beginning is now modified so that not all of the chlorine present in the melt is precipitated there with zinc, but part of the chlorine lead is left unprecipitated and the rest of the lead is recovered in an aqueous solution. With certain ores, e.g.
B. those with a particularly high iron and low lead content, it is even useful. The filling of the lead in the melt can be completely disregarded and the lead can only be obtained from an aqueous solution. t) a the reduction of iron by zinc takes place only in a melt poor in lead chloride, this reaction is switched off and after the present process
EMI1.2
In order to obtain the lead from an aqueous solution, the fiery-liquid melt in which all of the ore and gangue is suspended and which contains no silver and only small amounts of lead, is poured into waster. whereupon immediate solution occurs through granulation of the melt and heating of the water. The lead chloride remains dissolved in this hot liquid containing zinc chloride and thus allows the solid components to be separated from the liquid without loss. The latter either becomes the lead chloride partially
