Bei der Gewinnung des Zinkes in Muffeln, Röhren oder Tiegeln sammeln sich in diesen Gefäfsen in grofsen Mengen Rückstände an, welche aus denselben entfernt und als werthlos auf die Halde geschüttet werden.When the zinc is extracted in muffles, pipes or crucibles, it collects in these Vessels found in great quantities residues, which were removed from them and deemed worthless be dumped on the heap.
Sie bestehen der Hauptsache nach aus Kohle, Koksstückchen, metallischem Eisen, metallischem Blei und Zink in fein zertheiltem Zustande, aus Schwefeleisen, Bleiglanz,-unvollkommener abgerösteter Zinkblende, nicht vollkommen ausgenutztem Galmei, aus Schlackentheilchen, Thon, Sand u. s. w.They consist mainly of coal, bits of coke, metallic iron, metallic Lead and zinc in a finely divided state, from iron sulphide, galena, imperfect Roasted zinc blende, not completely used Calamine, from slag particles, clay, sand and so on.
Um dieselben in rationeller Weise in nutzbringende Stoffe umzuwandeln, wendet Er-. finder folgendes Verfahren an: Man schmilzt diese Rückstände ein und erhält hierbei unter Entwickelung von Zinkdämpfen wenig silberhaltiges Blei und Zinköxyd neben einer grofsen Menge eines Regulus, welcher aus etwa 70 pCt. Eisen besteht und der wie ein Schwamm in seinen Poren vollständig mit Einfachschwefeleisen (circa 30 pCt. des Regulus ausmachend) getränkt ist. Diesen Regulus,pulvert man, was ohne grofse Mühe geschehen kann. Hierbei fällt das Einfachschwefeleisen aus den Poren desselben heraus j und man erhält es in sehr fein zertheiltem pulverförmigen Zustande von grauschwarzer Farbe, während das Eisen die Gestalt von Eisenfeilspänen besitzt. Beide trennt man jetzt unter Anwendung von magnetischen Maschinen oder von Sieben.In order to transform them into useful substances in a rational way, he uses. finder the following procedure: These residues are melted down and under Development of zinc vapors, little silver-containing lead and zinc oxide, in addition to a large one Amount of a regulus, which consists of about 70 pCt. There is iron and which is like a sponge in its pores completely with single iron (making up about 30 pCt. of the regulus) is soaked. This Regulus, you powder what can be done without great effort. The single sulfur iron falls out of the pores out of the same, and it is obtained in a very finely divided powdery state of gray-black in color, while the iron has the shape of iron filings. Both they are now separated using magnetic machines or sieves.
W.endet man z. B. letztere Methode an, so bleibt das gröbere Eisen auf dem Sieb zurück, während das Einfachschwefeleisen durch die Maschen des Siebes fällt.If you use z. B. if the latter method is used, the coarser iron remains on the sieve, while the single sulfur iron falls through the mesh of the sieve.
Bei dem angegebenen Verfahren verliert man eine gewisse Quantität des in den Gesammtrückständen enthaltenen Zinkes.In the case of the procedure given, one loses a certain quantity of that in the total residues contained zinc.
Will man auch dieses gewinnen, so braucht man nur folgende zwei Operationen vor dem Schmelzen der Masse einzuschalten.If you want to win this too, you only need the following two operations before the Turn on melting the mass.
Man befreit dann zunächst die Rückstände durch Schlemmen oder durch Setzmaschinen von der circa 20 pCt. der Gesammtmasse betragenden Kohle und trennt darauf die übrigbleibende Masse mit magnetischen Maschinen in einen magnetischen Theil, welcher etwa 60 pCt. der Gesammtrückstände beträgt, und in einen nicht magnetischen Theil, dessen Masse 2.0 pCt. ausmacht. Erst jetzt schmilzt man den magnetischen Theil ein und behandelt darauf die Schmelzproducte, wie oben beschrieben, weiter, wobei man wie dort neben dem silberhaltigen Blei Eisen und bleihaltiges Einfachschwefeleisen erhält.The residues are then first freed by feasting or using setting machines of the approx. 20 pCt. of the total mass and separates the remaining coal Mass with magnetic machines into a magnetic part, which is about 60 pCt. of the total residue, and into a non-magnetic part, the mass of which is 2.0 pCt. matters. Only now is the magnetic part melted down and the Melt products, as described above, where, as there, in addition to the silver-containing lead, iron and lead-containing monosulfur iron receives.
Der nicht magnetische Theil ist der Theil, welcher die gröfste Menge des Zinkes der Gesammtrückstände enthält. Er besteht aufser aus Kieselsäure, Kalk, Magnesia, Eisenoxyd und Thonerde aus circa 6 bisiopCt. Zink, sowie circa 3 bis ι ο pCt. Blei.The non-magnetic part is that part which contains the greatest quantity of zinc Contains total residues. It also consists of silica, lime, magnesia, iron oxide and Clay from about 6 bisiopCt. Zinc, as well approx. 3 to ι ο pCt. Lead.
Das Befreien der Masse von Kohle kann event, auch unterbleiben und direct die Trennung in einen magnetischen und einen nicht magnetischen Theil nebst Kohle durch magnetische Maschinen stattfinden, wobei dann der magnetische Theil nebst der Kohle dieselbe Verwendung finden würde, wie der nicht magnetische Theil allein.The freeing of the mass of coal can also be omitted and direct the event Separation into a magnetic and a non-magnetic part with carbon Magnetic machines take place, in which case the magnetic part and the carbon are the same Would find use as the non-magnetic part alone.
Die nach dem angegebenen Verfahren erhaltenen Pruducte lassen sich wie folgt verwerthen: . ■ ■The products obtained by the specified process can be used as follows: . ■ ■
Das circa Y10 pCt. und mehr Silber enthaltende Blei kann nach bekannten Methoden entsilbert, das Zinkoxyd, mit Kohle gemengt, zur Zinkfabrikation verwendet werden, während sich das Eisen, welches ι bis 1,5 pCt. Schwefel enthält, zur Herstellung von Eisenvitriol, Blutlaugensalz, als Gasreinigungsmasse, zu hydrometallurgischen Zwecken, sowie bei der Niederschlagsarbeit oder, mit gröfseren Quantitäten schwefelfreien Eisens gemischt, zur Gufseisenfabrikation, oder unter Zusatz von Eisenerzen bezw. durch theilweises Rösten gröfstentheils vom Schwefel befreit und zum Theil in Eisenoxyd umgewandelt, zur Herstellung eines silberglänzenden, weichen, Schmiedeisen ähnlichen Eisens verwenden läfst.The approximately Y 10 pCt. and lead containing more silver can be desilvered according to known methods, the zinc oxide, mixed with coal, can be used for zinc production, while the iron, which is up to 1.5 pCt. Contains sulfur, for the production of iron vitriol, blood liquor salt, as a gas cleaning compound, for hydrometallurgical purposes, as well as for precipitation work or, mixed with larger quantities of sulfur-free iron, for the manufacture of cast iron, or with the addition of iron ores or. largely freed from sulfur by partial roasting and partially converted into iron oxide, can be used for the production of a silvery, soft iron-like iron.
Das Einfachschwefeleisen, welches im Durchschnitt 6 bis 8 pCt. Blei an Schwefel gebunden enthält, kann entweder zur Schwefelwasserstoffentwickelung dienen oder, in Schwefelsäurefabriken zur Ausnutzung des Schwefels abgeröstet, der Rückstand entbleit und die übrigbleibende Masse als Eisenerz benutzt werden.The single sulfur iron, which on average 6 to 8 pCt. Lead bound to sulfur contains, can either be used for the evolution of hydrogen sulfide or, in sulfuric acid factories roasted to make use of the sulfur, the residue and the remaining residue Mass to be used as iron ore.
Die unmagnetischen, zinkreichen Rückstände werden als Beimengung zu reichen Zinkerzen verwendet und auf Zink verhüttet.The non-magnetic, zinc-rich residues are added to rich zinc ores used and smelted on zinc.
