Patentirt im Deutschen Reiche vom 4. August 1895 ab.Patented in the German Empire on August 4, 1895.
Bei der Behandlung von Zinkerzen condensirt sich ein Theil des destillirten Metalles und schlägt als Staub an den Wänden der Retorte nieder.In the treatment of zinc ores, part of the distilled metal condenses and precipitates as dust on the walls of the retort.
Dieser Zinkstaub, welcher. sich in ziemlichen Mengen bildet, wird in verschiedenen Gewerbszweigen, sowie in den chemischen Laboratorien als Reduktionsmittel verwendet. Diese Verwendungsweise verbraucht jedoch nur einen sehr geringen Theil der Production, und um das Metall- zu gewinnen, bringt man bis jetzt diesen Staub wieder in die Verarbeitung, als ob er Erz wäre.That zinc dust, which. forms in considerable quantities, is used in various branches of industry, as well as used in chemical laboratories as a reducing agent. This way of using but consumes only a very small part of the production, and um To mine the metal, one brings this dust back into the processing until now, as whether he was ore.
Mehrere Verfahren sind angewendet worden, um den Zinkstaub direct zu reduciren, sind aber in den meisten Hütten wegen verschiedener durch die Praxis bewiesener Uebelstände wieder aufgegeben worden.Several methods have been used to reduce the zinc dust directly, are but in most huts because of various evils proven by practice been abandoned again.
Durch das vorliegende Verfahren wird Zinkstaub direct in Metall umgewandelt.The present process converts zinc dust directly into metal.
Man bringt den vorher mit feingemahlenem Harze vermischten Zinkstaub in einen gufseisernen, eisernen oder aus feuerfestem Thon hergestellten Schmelztiegel. Das beizumischende Quantum Harz hängt von dem muthmafslichen Gehalte des Zinkstaubes an .Metall ab.The zinc dust, previously mixed with finely ground resin, is placed in a cast-iron, crucibles made of iron or of refractory clay. That to be mixed in The amount of resin depends on the presumed content of zinc dust in the metal.
Der Apparat mufs mit einer Oeffnung versehen sein, aus welcher die flüchtigen Theile des Harzes entweichen können.The apparatus must be provided with an opening from which the volatile parts the resin can escape.
Die Temperatur wird dann nach und nach bis auf Dunkelrothgluth erhöht und auf dieser. Höhe bis zur vollständigen Reduktion des im Zinkstaube enthaltenen Metalles erhalten. Das reducirte Metall schmilzt und sammelt sich im unteren Theile des Apparates an.The temperature is then gradually increased up to dark red glow and on this. Preserved height until the metal contained in the zinc dust has been completely reduced. That The reduced metal melts and accumulates in the lower part of the apparatus.
