KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft eine weitere Ausbildung des bekannten Aufschließverfahrens geschwefelter Erze oder Metalle mittels sauren schwefelsauren Natriums, und zwar besteht das Neue darin, daß der Schwefel der Metallsulfide als Schwefelsäure gewonnen und in dieser Form zur Rückbildung des bei dem Verfahren erforderlichen sauren Alkalisulfates aus dem endgültig erhaltenen schwefelsauren Alkali benutzt wird.The present invention relates to a further embodiment of the known unlocking method sulphurized ores or metals by means of acidic sulphate of sodium, and that is New in the fact that the sulfur of the metal sulfides is obtained as sulfuric acid and in this Form for the regeneration of the acidic alkali sulfate required in the process from the sulfuric acid alkali finally obtained is used.
In den einzelnen Stufen des Verfahrens wird beispielsweise nach der nachfolgenden Formel Schwefelzink und Schwefelblei mit saurem schwefelsauren Natrium aufgeschlossen, indem sich hierbei der zur Rückbildung des schwefelsauren Natriums dienende Schwefelwasserstoff bildet.In the individual stages of the process, for example, according to the following formula Zinc sulfur and lead sulfur are digested by adding acidic sodium sulphate the hydrogen sulphide used to re-form the sodium sulphate forms.
Zn S + 2 Λ Zn S + 2 Λ
Zn SO4 + Na2 SO4 + H2 S.Zn SO 4 + Na 2 SO 4 + H 2 S.
Pb S + 2NaHSO4 = Pb S + 2NaHSO 4 =
Pb SO4 + Na2SO4 + H2S.Pb SO 4 + Na 2 SO 4 + H 2 S.
H2S + 2,0 = SO2 + H2O.H 2 S + 2.0 = SO 2 + H 2 O.
Wenn Eisensulfid vorhanden ist, wird dieses folgendermaßen in Eisenoxyd umgewandelt:If iron sulfide is present, it is converted into iron oxide as follows:
FeS2+ 2NaHSOt + 2O =FeS 2 + 2NaHSOt + 2O =
Fe SO, + Na2 SO4 + SO2 + H2S.Fe SO, + Na 2 SO 4 + SO 2 + H 2 S.
2 Fe SO4 + O — Fe2 O3 + 2 SO3. 2 Fe SO 4 + O - Fe 2 O 3 + 2 SO 3 .
Nach dem Bilde der Formeln werden Zinksulfide mit saurem schwefelsaurem Alkali durch Schmelzen und Rösten in leicht zu verarbeitende Sulfate übergeführt. Während jedoch Zinksulfat von dem Bleisulfat ohne Schwierigkeit durch Auslaugen der Schmelze abgeschieden werden kann, ist die hierbei erhaltene Lösung von Zinksulfat und Natriumsulfat, auf welch letztere es bei der Rückbildung ankommt, als solche noch nicht ohne weiteres verwendbar. Es wird daher in der Doppellösung zwecks Gewinnung der Natriumsulfatlösung und Trennung der Zinkverbindungen Zinksulfat in der bekannten Weise mit Bariumhydrat gefällt entsprechend der Formel:According to the formulas, zinc sulphides are treated with acidic sulfuric acid alkali Melting and roasting converted into easy-to-process sulfates. However, while zinc sulfate from which lead sulfate can be deposited without difficulty by leaching the melt, is the solution obtained in this way of zinc sulphate and sodium sulphate, which latter is important for regression than such cannot be used without further ado. It is therefore used in the double solution for the purpose Extraction of the sodium sulphate solution and separation of the zinc compounds in the zinc sulphate known way with barium hydrate pleases according to the formula:
ZnSO4 + BaH2O2 = ZnSO 4 + BaH 2 O 2 =
Zn H2 O2 + BaS O4.Zn H 2 O 2 + BaS O 4 .
Der hierbei sich bildende Niederschlag wird von der Lösung des schwefelsauren Natriums durch Dekantieren oder Filtrieren oder Waschen abgeschieden und bildet ein als Farbstoff verwertbares Zwischenerzeugnis.The precipitate which forms in this process is removed from the solution of sodium sulfuric acid deposited by decanting or filtering or washing and forms one that can be used as a dye Intermediate product.
Das nunmehr freie neutrale Natriumsulfat, welches in Lösung verbleibt, wird weiterhin durch Behandlung mit Schwefelsäure, welche aus dem bei der Röstung abgeschiedenen Schwefelwasserstoff mittels Oxydation erhalten wird, in Natriumbisulfat übergeführt. Es kann also nach dem Verfahren eine bestimmte Menge von Natriumbisulfat eine unbegrenzte Menge sulfidisches Erz umsetzen.The now free neutral sodium sulfate, which remains in solution, continues to be by treatment with sulfuric acid, which is deposited from the roasting Hydrogen sulfide is obtained by oxidation, converted into sodium bisulfate. It can so according to the method a certain amount of sodium bisulfate an unlimited amount convert sulphidic ore.

ι. Verfahren zur Wiedergewinnung des beim Rösten und Auslaugen von Schwefelerzen angewendeten Natriumbisulfates mit Hülfe des in den Erzen enthaltenen Schwefels, dadurch gekennzeichnet, daß der beim Rösten der Erze entwickelte Schwefelwasserstoff in Schwefelsäure übergeführt und diese auf die bei der Verarbeitung der Lauge als Rest erhaltene neutrale Natriumsulfatlösung zwecks Überführung in Bisulfat zur Einwirkung gebracht wird.Patent Claims:
ι. Process for the recovery of the sodium bisulphate used in roasting and leaching of sulfur ores with the aid of the sulfur contained in the ores, characterized in that the hydrogen sulphide developed during roasting of the ores is converted into sulfuric acid and this is added to the neutral sodium sulphate solution obtained as a residue during processing of the lye Conversion into bisulfate is brought into action.
