Verfahren zur Gewinnung von Quecksilber aus Erzen oder anderen Rohstoffen.
Die Erfindung bezieht sich auf ein Verfahren zur Gewinnung von Quecksilber aus Erzen oder anderen Rohstoffen und betrifft Verbesserungen hinsichtlich der Gewinnungskosten und der Ausbeute.
Wenn Erze usw., welche Quecksilbersulfid enthalten, mit einer Schwefelalkali und Alkalihydrat enthaltenden Lösung behandelt werden, wird die Quecksilberverbindung aus dem Erz herausgelöst ; vorzugsweise besteht das Lösungsmittel aus Schwefelnatrium und Ätznatron.
Die auf diese Weise gewonnene quecksilberhaltige Lösung wird gemäss der Erfindung mit Aluminium oder Chrom versetzt, wodurch die in Lösung enthaltene Quecksilberverbindung als Quecksilbermetall in fein verteiltem Zustande ausgefällt wird, während das zur Ausfällung benutzte Metall in Lösung geht.
Eine vorzugsweise Ausführungsart der Ausfällung von Quecksilber aus der Lösung besteht darin, dass man das Ausfällungsmetall in fein verteiltem Zustande hinzufügt und das Gemenge starkem Umrühren aussetzt.
Das ausgefällte Quecksilberpulver wird gerieben, um die sehr gering bemessenen Teilchen in innige Berührung miteinander zu bringen und das Metall in den flüssigen Zustand überzuführen.
Das Raffinieren für die Handelsware erfolgt mittels Durchseihens durch ein Gewebe-oder Gemslederseihtuch. Der chemische Vorgang des Verfahrens besteht darin, dass beim Zusatz von Aluminium oder Chrom zu einer alkalisulfid-und alkalihydrathältigen, das Quecksilber in Gestalt von Schwefelquecksilber enthaltenden Lösung der an das Quecksilber gebundene Schwefel in Verbindung mit Alkali tritt und Schwefelalkali entstehen lässt, wodurch der Gehalt des Lösungsmittels an Schwefelalkali gesteigert wird. Die Reaktionen sind folgende : i. Beim Auflösungsprozess :
EMI1.1

Process for extracting mercury from ores or other raw materials.
The invention relates to a method of extracting mercury from ores or other raw materials and relates to improvements in extraction costs and yield.
When ores, etc. containing mercury sulfide are treated with a solution containing alkali sulfur and alkali hydrate, the mercury compound is dissolved out of the ore; preferably the solvent consists of sodium sulphide and caustic soda.
According to the invention, the mercury-containing solution obtained in this way is mixed with aluminum or chromium, whereby the mercury compound contained in the solution is precipitated as mercury metal in a finely divided state, while the metal used for the precipitation goes into solution.
A preferred embodiment of the precipitation of mercury from the solution consists in adding the precipitated metal in a finely divided state and subjecting the mixture to vigorous stirring.
The precipitated mercury powder is rubbed in order to bring the very small particles into intimate contact with one another and to convert the metal into the liquid state.
Refining for the merchandise is done by straining it through a tissue or chamois leather silk cloth. The chemical process of the process consists in the fact that when aluminum or chromium is added to an alkali sulphide and alkali hydrate containing solution, the mercury in the form of mercury-containing sulfur, the sulfur bound to the mercury, comes into connection with alkali and creates alkali-sulfur, whereby the content of the Solvent is increased to sulfur alkali. The reactions are as follows: i. During the dissolution process:
EMI1.1
2. during precipitation:
EMI1.2
