KLASSE -4O: Hüttenwesen.CLASS -4O: Metallurgy.
Es ist bekannt, dafs das metallische Blei aus den schwefelhaltigen Erzen desselben in der Weise gewonnen werden kann, dafs man letztere in geschmolzenem Zustande in eine Birne giefst, welche Stücke erhitzten Schmied- oder Gufseiseris enthält. Der Schwefel des geschmolzenen Erzes wird von dem Eisen absorbirt, welches sich hierdurch iri Schwefeleisen verwandelt, während das freigewordene Blei in der Birne zu Boden fällt und abgestochen werden kann.It is known that the metallic lead from its sulphurous ores is found in the It can be obtained in a way that the latter can be put in a pear in a molten state giefst, which contains pieces of heated blacksmith or cast iron ice. The sulfur of the melted Ore is absorbed by the iron, which is thereby converted into iron sulphide transformed while the released lead falls to the ground in the pear and stabbed can be.
Die vorliegende Neuerung besteht in einer Abänderung dieses Verfahrens dahin, dafs die Birne zunächst mit den schwefelhaltigen Erzen beschickt wird, worauf man geschmolzenes Eisen in die Birne einfliefsen läfst.The present innovation consists in a modification of this procedure so that the The pear is initially charged with the sulfur-containing ores, after which it is melted Let iron flow into the pear.
Sobald das Erz durch das Eisen flüssig wird, verbindet sich der Schwefel mit dem Eisen zu Schwefeleisen, während das frei werdende metallische Blei in der Birne zu Boden fällt. Letztere kann so eingerichtet sein, dafs man entweder nur das Blei oder zuerst das geschmolzene Eisen und dann das Blei abfliefsen lassen kann. Hierbei kann eine gewöhnliche Giefspfanne als Birne dienen. Letztere kann ferner auch die Gestalt einer grofsen Giefsform haben, welche man in der ganzen Länge mit Erz belegt, auf welches dann das flüssige Eisen gegossen wird. Läfst man dann das Eisen etwas erkalten, so dafs man die Form an dem einen Ende etwas anheben kann, so wird das Blei am anderen Ende herausfliefsen.As soon as the ore becomes liquid through the iron, the sulfur combines with the Iron to sulfur iron, while the released metallic lead in the pear to Floor falls. The latter can be arranged in such a way that either only the lead or drain the molten iron first and then the lead. Here a ordinary pan to serve as a pear. The latter can also take the form of a large one Have a mold, which is covered with ore along its entire length, on which then the liquid iron is poured. If you then let the iron cool down a bit, you will If the shape can lift a little at one end, the lead will flow out at the other end.
Schliefslich kann man der Birne auch die Form einer geneigten Rinne geben, in welche das Erz eingelegt wird. Das geschmolzene Eisen wird am oberen Ende in die Rinne gegossen; beim Niederfliefsen kommt es mit den Bleierzen in Berührung, schmilzt diese, veranlafst durch Aufnahme des Schwefels das Freiwerden des Bleis und gelangt mit diesem zusammen in einen am unteren Ende der Rinne angeordneten Behälter, auf dessen Boden sich das Blei sammelt.Finally, the pear can also be given the shape of an inclined groove into which the ore is inserted. The molten iron is at the top in the gutter poured; when it comes into contact with the lead ores, it melts, causes the lead to be released by absorbing the sulfur and arrives with it together in a container arranged at the lower end of the channel, on the bottom of the container the lead collects.
Bei Benutzung letzterwähnter Vorrichtung kommt jedes Eisentheilchen mit Bleierz in Berührung und ertheilt letzterem einen kleinen Stofs, was auf das .augenblickliche Schmelzen des Erzes äufserst vortlieilhaft einwirkt.When the last-mentioned device is used, every piece of iron comes into contact with lead ore and gives the latter a little substance as to the instantaneous melting of the ore is extremely beneficial.
Wenn die Menge des geschmolzenen Eisens gröfser ist, als zur Durchführung des Processes erforderlich ist, so kann der überflüssige Rest in Barren gegossen werden, welche in einem Cupolofen wiederum zur Benutzung kommen können.When the amount of molten iron is greater than that required for carrying out the process is required, the superfluous remainder can be poured into ingots, which in one Cupola oven in turn can be used.
Selbstredend ist es zweckmäfsig, zur Ausübung der vorbeschriebenen Processe das Bleierz so rein als möglich zu sortiren. Je weniger Schwefel dasselbe enthält, desto weniger Eisen ist natürlich erforderlich; am vorteilhaften ist es daher, das Erz vorher zu rösten und dasselbe womöglich in erhitztem Zustande anzuwenden.It goes without saying that it is useful to carry out the processes described above To sort lead ore as pure as possible. The less sulfur it contains, the more less iron is required, of course; it is therefore most advantageous to close the ore beforehand toast and use the same if possible in a heated state.
