Description

Verfahren zur Verhüttung von zinnfreien Bleiaschen in einem Flammofen. Die Verarbeitung von Bleiaschen ist bisher in Flammöfen mit tiefgebauter Sohle und, bei einer Temperatur von iooo° .durchgeführt worden.Process for smelting tin-free lead in a furnace. The processing of lead ashes has so far been in flame furnaces with a deeply built base and, has been carried out at a temperature of 100 °.

Diese Verarbejitungsweise hat eine Reihe von erheblichen Nachteilen gezeitigt. Die Enthleiwng wird unvollständig, das Verfahren langwierig und daher kostspielig, die erzeugte Schlacke bleireich.This method of processing has a number of significant disadvantages brought forth. The loan will be incomplete, the procedure lengthy and therefore expensive, the slag produced is rich in lead.

Um diese Mängel zubeseitigen, werden die Bleiaschen gemäß der vorliegenden Erfindung in einem Flammofen mit flacher Sohle unter Zugabe von etwa io Prozent eines leichtflüssigen Salzes, wie z. B. Natriumsulfat, und eihiigen wenigen Prozenten Reduktionsistoff eingeschmolzen und bei einer Temperatur von i'ioo ,bis i2oo°. verarbeitet.In order to remedy these deficiencies, the lead tubes according to the present Invention in a flame furnace with a flat sole with the addition of about 10 percent a liquid salt, such as. B. sodium sulfate, and a few percent Reducing agent melted and at a temperature of i'ioo, to i2oo °. processed.

Diese Bedingungen haben auf die Verarbeitung der'Bleiaschen einen überraschend günstigen Einfluß, so daß nach kurzer .Zeit eine fast bleifreie, leichtflüssige Schlacke und, eine fast quantitative Ausbeute des Bleis erhalten wird.These conditions have an effect on the processing of the lead Surprisingly favorable influence, so that after a short time an almost lead-free, easily fluid Slag and, an almost quantitative yield of lead is obtained.

Es ist zwar bekannt, zur Behandlung bleihaltiger- Erze eine Mischung von Ntatriumsulfat und Kahle anzuwenden.It is known to use a mixture to treat ores containing lead of Sodium Sulphate and Kahle apply.

Es ist ferner vorgeschlagen, zinnhaltige Bleiaschen zum .Zwecke der Entfernung des Zinnes mit neutralen A .likalisalzen im Flammofen zu verschmelzen.It is also proposed to use tin-containing lead for .Zwecke the Removal of the tin to melt with neutral alkali metal salts in a flame furnace.

Alis neu wi@,d im vorliegenden Falle -die Verivendung eines leicht schmelzbaren Salzes, z. B. Natriumsulfat, .mit Reduktionsstoff zur Verarbeitung solcher Bleiaschen, welche kein Zinn enthalten, im Flammofen ufid bei einer Temperatur von i ioo Ibis i2oo° erachtet.Alis neu wi @, d in the present case - the use of an easy fusible salt, e.g. B. sodium sulfate, .with reducing agent for processing Such lead bottles, which do not contain tin, are placed in the furnace at one temperature considered by i ioo Ibis i2oo °.
