Description
Verarbeitung antimonhaltiger Gold-Silbererze. Die Erfindung bezieht sich auf ein Verfahren zur Verarbeitung von antimonhaltigen Gold-Silbererzen.Processing of antimony-containing gold-silver ores. The invention relates focuses on a process for processing gold-silver ores containing antimony.
Es ist allgemein bekannt, daß antimonhaltige Golderze nach den üblichen Entgoldungsverfahren (Amalgamation mit Quecksilber, Cyanierungs-und Chlorationsverfahren) nicht ohne große Verluste an Edelmetallen und nur mit sehr hohen Betriebskosten verarbeitet werden können.It is well known that antimony-containing gold ores after the usual Gold removal process (amalgamation with mercury, cyanation and chlorination processes) not without great losses of precious metals and only with very high operating costs can be processed.
Man hat bereits verschiedene Vorschläge gemacht, um Gold und Silber aus antimonhaltigen Erzen abzutrennen. Unter anderem wurde vorgeschlagen, solche Erze mit Alkalikarbonatlösungen und Alkalihydratlösungen auszulaugen, um dadurch das Schwefelantimon in Lösung zu bringen. Diese Lösungen wirken jedoch sehr langsam, so daß die Arbeit nicht nur sehr lange Zeit in Anspruch nimmt, sondern auch unvollständig ist. Läßt man jedoch gemäß der Erfindung auf die Erze verdünnte Alkalikarbonatlösung in der Wärme und unter Umrühren bei gleichzeitigem Zusatz von genügend gebranntem Kalk einwirken, so geht die Einwirkung und Auslaugung sehr schnell und vollständig vor sich, denn es bildet sich hierbei Alkalihydrat, das im Entstehungszustande sofort sehr energisch auf die Erze unter Bildung von Sulfantimoniatlösung und dessen Doppelsalzen einwirkt, ohne daß hierbei die Edelmetalle mitgelöst werden. Diese Lösung kann sehr leicht von den ungelösten Edelmetallrückständen durch Filtration oder Dekantation getrennt werden; die Antimoniatlösung (Filtrat) wird entweder durch Elektrolyse auf metallisches Antimon verarbeitet oder durch Einleiten von Kohlensäure oder kohlensäurehaltige Gase zersetzt, wobei Schwefelantimon niedergeschlagen wird und zur weiteren Verarbeitung gelangt.Various proposals have already been made about gold and silver separated from ores containing antimony. Among other things, it was suggested such Leach ores with alkali carbonate solutions and alkali hydrate solutions to thereby to bring the sulfur antimony into solution. However, these solutions work very slowly, so that the work not only takes a long time, but is also incomplete is. However, according to the invention, alkali carbonate solution diluted on the ores is left in the warmth and with stirring with the simultaneous addition of enough fired If lime acts, the effect and leaching is very quick and complete in front of you, because alkali hydrate is formed in the process, which is immediately in the state of origin very energetically on the ores with the formation of sulfantimoniate solution and its double salts acts without the precious metals being dissolved. This solution can be very easily removed from the undissolved precious metal residues by filtration or decantation be separated; the antimoniate solution (filtrate) is either made by electrolysis Processed on metallic antimony or by introducing carbonated or carbonated Gases decomposed, sulfur antimony is precipitated and for further processing got.
Es wurde festgestellt, daß aus wirtschaftlichen Gründen zur Fällung des Schwefelantimons auch die gewöhnlichen Rauchgase verwendet werden können, welche überall an Arbeitsstätten zur Verfügung stehen. Dieselben enthalten i o bis 15 Prozent Kohlensäure und sind sehr zweckmäßig verwendbar.It was found that, for economic reasons, the usual flue gases, which are available everywhere at workplaces, can also be used to precipitate the sulfur antimony. They contain 10 to 15 percent carbonic acid and are very useful.
Nach der Behandlung des Filtrats mit Kohlensäure wird aus der Antimoniatlösung das Alkalikarbonat zurückgebildet und kann wieder zu neuen Auflösungen von frischen Erzen verwendet werden.After treating the filtrate with carbonic acid, the antimonate solution becomes The alkali carbonate is regressed and can again lead to new dissolutions of fresh Ores are used.
Der aufgelöste Edelmetallrückstand aus dieser Behandlung wird auf üblichem Wege nach den Cyankali- oder Chlorationsverfahren verarbeitet.The dissolved precious metal residue from this treatment is on Processed in the usual way by the cyan potassium or chlorination process.
