Patentirt im Deutschen Reiche vom 31. Oktober 1895 ab.Patented in the German Empire on October 31, 1895.
Vorliegende Erfindung hat ein Verfahren zur Fällung von Edelmetallen aus den bei der Extraction aus Erzen gebildeten Lösungen derselben zum Gegenstande.The present invention has a method for the precipitation of noble metals from the Extraction of their solutions formed from ores as an object.
Gegenwärtig werden schwache Lösungen von Chlor, Cyankalium und anderen Lösungsmitteln bei der Behandlung von Erzen, von Gold und anderen Edelmetallen in grofsen Mengen benutzt, um die Edelmetalle zu lösen; nachher benutzt man gewöhnlich Zinkspä'ne oder Granalien, um das Edelmetall aus der Lösung auszufällen.At present, weak solutions of chlorine, potassium cyanide and other solvents are used in the treatment of ores, gold, and other precious metals in large quantities Quantities used to dissolve the precious metals; afterwards one usually uses zinc shavings or granules to precipitate the precious metal out of solution.
Auch Eisenvitriol oder Holzkohle wurden zur Fällung der Edelmetalle aus diesen verdünnten Lösungen benutzt.Iron vitriol or charcoal were also diluted from these to precipitate the precious metals Solutions used.
Diesen bekannten Verfahren gegenüber unterscheidet sich das vorliegende dadurch, dafs man das Edelmetall aus der Lösung fällt, indem man diese letztere durch ein Filter oder durch mehrere Filter nach einander gehen läfst, die aus gekörnter Holzkohle bestehen, welche mit einem neutralen Sulfat (Aluminiumsulfat, Ferrosulfat) imprägnirt ist. Man erzielt so eine vollständigere und raschere Fällung, das in der Kohle ausgeschiedene Metall wird durch Ausschmelzen gewonnen.The present one differs from these known processes in that the precious metal is precipitated from the solution by passing the latter through a filter or through several filters that are made of grained charcoal, which with is impregnated with a neutral sulfate (aluminum sulfate, ferrous sulfate). That way you get a more complete one and faster precipitation, the metal precipitated in the coal is melted out won.
Man zerkleinert die Holzkohle zu Körnern von beiläufig Schrotgröfse und scheidet allen Staub sorgfältig ab. Die Körner sättigt man mit einer Lösung von Aluminium-, Eisen-, Zinkoder Kupfersulfat.The charcoal is crushed into grains of casually shot-size, and all of them are separated Dust off carefully. The grains are saturated with a solution of aluminum, iron, or zinc Copper sulfate.
Man benutzt am besten zwei oder mehr Lagen des Filtrirmaterials, mit von oben nach unten wachsender Korngröfse. Es ist z. B. zweckmäfsig, drei Lagen von je ca. 10 cm Stärke zu verwenden. Die Körner der obersten Lage haben ca. 1,5 mm Durchmesser, jene der zweiten ca. 3 mm und die der dritten 6 mm Durchmesser.It is best to use two or more layers of the filter material, from top to bottom grain size increasing below. It is Z. B. expedient, three layers of about 10 cm each To use starch. The grains of the top layer are approx. 1.5 mm in diameter, those of the the second about 3 mm and that of the third 6 mm in diameter.
Für Gold ist Aluminiumsulfat am geeignetsten und für Silber Eisensulfat; sind beide Metalle im Erz vorhanden, so können diese Sulfate entweder zusammen oder in auf einander folgenden Filtern benutzt werden. In allen Fällen macht man die Sulfate neutral, und zwar am besten durch Zusatz von Natriumsilicat. Die getränkte Holzkohle wird getrocknet und bis zur Rothglut erhitzt. Nach dem Abkühlen ist sie zur Herstellung der Filter bereit.Aluminum sulfate is most suitable for gold and iron sulfate for silver; are both metals present in the ore, these sulfates can either be together or in on top of each other the following filters can be used. In all cases one makes the sulphates neutral, that is best by adding sodium silicate. The soaked charcoal is dried and up heated to red embers. After cooling, it is ready for making the filters.
Läfst man die Flüssigkeit durch das Filter laufen, so wird das Edelmetall- in der Kohle abgelagert, die Flüssigkeit bleibt im übrigen unverändert und es entsteht kein Cyanidverlust. Es ist vorzuziehen, zwei oder mehr Filter nach einander zu benutzen. Wenn das Filter hinreichend viel Edelmetall aufgenommen hat, wird letzteres ausgeschmolzen.If you let the liquid run through the filter, the precious metal becomes in the coal deposited, the liquid remains otherwise unchanged and there is no loss of cyanide. It is preferable to use two or more filters one after the other. If the filter is sufficient has absorbed a lot of precious metal, the latter is melted out.
