abfallenden faulen Laugen.falling rotten liquor.
Patentiert im Deutschen Reiche vom 3. Mai 1906 ab.Patented in the German Empire on May 3, 1906.
Das vorliegende Verfahren bezweckt die rentable Verarbeitung der bei der Kupfernickelsteinelektrolyse fallenden faulen Laugen und sonstigen Nebenprodukte, wie Anodenschlämme u. dgl. Dabei soll reines Kupfer und kupferfreies Nickel gewonnen werden.The present process aims at the profitable processing of the copper-nickel brick electrolysis falling rotten alkalis and other by-products, such as anode sludge and the like and copper-free nickel can be obtained.
Zu diesem Zwecke wird in folgender Weise , verfahren:For this purpose, the following procedure is used:
Garnierit oder ähnlich zusammengesetzte ίο Nickelerze und Magnetkies oder andere schwefelhaltige Kupfernickelerze werden in passender Weise gattiert und mit Koks im Schachtofen auf Rohstein verschmolzen. Der Magnetkies fungiert in diesem Falle als Schwefelungsmittel für den Garnierit zur Steinbildung, während der Garnierit die nötige Kieselsäure zur Verschlackung der überschüssigen Basen des Magnetkieses liefert.Garnierite or similarly composed ίο nickel ores and magnetic gravel or others Sulfur-containing cupronickel ores are suitably charged and mixed with coke in the Shaft furnace fused on rough stone. The magnetic gravel acts as a Sulphurizing agent for the garnierite for stone formation, while the garnierite the necessary Silica supplies to the slagging of the excess bases of the magnetic gravel.
Der so erhaltene Rohstein wird in üblicher Weise auf Konzentrationsstein verarbeitet, wobei man auf eine möglichst vollständige Verschlackurig des Eisens bedacht ist.The raw stone obtained in this way is processed in the usual way on concentration stone, whereby one is concerned with the most complete slagging of the iron.
Der konzentrierte Kupfernickelstein wird in bekannter Weise elektrolytisch weiter verarbeitet. Der Stein bildet die Anode, als Kathode dient ein Blech aus Kupfer oder sonst passendem Material, der Elektrolyt besteht in einer Lösung von Kupfervitriol mit freier Schwefelsäure. An der Anode gehen Eisen, Kupfer, Nickel in Lösung, die Edelmetalle, elementarer Schwefel, Kieselsäure, etwas untersetztes Metallsulfid usw. bleiben als unlösliche Schlämme zurück. Diese werden nach dem Auswaschen und Trocknen durch ein geeignetes Lösungsmittel von dem elementaren Schwefel befreit und die als Extraktionsrückstände verbleibenden Edelmetalle, sulfidischen Reste usw. auf Gewinnung ihrer wertvollen Bestandteile weiter verarbeitet. The concentrated copper-nickel brick is further processed electrolytically in a known manner. The stone forms the anode, a sheet made of copper or serves as the cathode Otherwise suitable material, the electrolyte consists of a solution of copper vitriol with free sulfuric acid. At the anode, iron, copper and nickel go into solution, the precious metals, elemental sulfur, silica, somewhat stocky metal sulfide, etc. remain as insoluble sludge. These will be after washing out and drying freed from the elemental sulfur by a suitable solvent and the as Extraction residues remaining precious metals, sulphidic residues etc. on recovery their valuable components are further processed.
Zu diesem Zweck röstet man die Rückstände vorsichtig ab, um die Metalle Kupfer, Nickel, Eisen usw. als Oxyde, das Silber tunlichst als wasserlösliches Sulfat zu erhalten. For this purpose, the residues are carefully roasted to remove the metals copper, Nickel, iron, etc. as oxides, silver as water-soluble sulfate if possible.
Im Verlauf der Elektrolyse reichert sich das Nickel in den Bädern mehr und mehr an; ist eine gewünschte Nickelkonzentration erreicht, so werden die Laugen abgesetzt und aufgearbeitet.In the course of the electrolysis, the nickel accumulates more and more in the baths at; once the desired nickel concentration has been reached, the alkalis are deposited and worked up.
Die abgesetzten Bäderlaugen halten in der Hauptsache Nickelsulfat, Kupfersulfat, freie Schwefelsäure, wenig Eisensulfat und andere Verunreinigungen.The settled bath liquors mainly keep nickel sulphate and copper sulphate free Sulfuric acid, little iron sulfate and other impurities.
Ihre Aufarbeitung erfolgt in zweifacher Weise.They are processed in two ways.
Ein Teil der Laugen wird verwendet, um die gerösteten Anodenschlämme wieder nutzbar zu machen.Some of the lye is used to make the roasted anode sludge usable again close.
Die freie Säure der Laugen wird durch die Oxyde des gerösteten Gutes neutralisiert, man erhält die entsprechenden Vitriole, die durch fraktionierte Kristallisation und auf chemischem Wege getrennt werden unter Gewinnung von Zementsilber und reinen Vi-The free acid of the lye is neutralized by the oxides of the roasted goods, the corresponding vitriols are obtained by fractional crystallization and on separated chemically to obtain cement silver and pure vitamins
