Description
Das den Gegenstand der Erfindung bildendeThat forming the subject of the invention
Verfahren bezweckt eine Beschleunigung und Verbesserung des Auslaugeprozesses bei kupfer-, zink-, silber- usw. haltigen Kiesabbränden durch Spülung. ' ■ .Process aims to accelerate and improve the leaching process for copper, zinc-, silver- etc. containing gravel burns by flushing. '■.
Nach den bisher üblichen Verfahren wurden die gemahlenen und chlorierten gerösteten heißen Abbrände vermittels Wagen oder anderer Transportmittel in die LaugebotticheThe ground and chlorinated roasted ones were roasted according to the usual procedures hot burns by means of carts or other means of transport in the lye tubs
ίο gebracht. Dann ließ man verdünnte Lauge oder Säure auf den Inhalt der Bottiche laufen und aus dem Boden derselben abfließen und befreite so das unlösliche Erz. von den löslichen Metallsalzen. Bei diesem Verfahren bildeten sich Klumpen, in die die Flüssigkeit nur langsam eindringen konnte, so daß der Prozeß einen oder mehrere Tage in Anspruch nahm. Dabei wurden die Bottiche und deren Filterböden durch das heiße Erz stark angegriffen und die Arbeiter belästigt.ίο brought. Then diluted lye was left or acid run on the contents of the vats and drain from the bottom of the same and thus freed the insoluble ore from the soluble metal salts. In this procedure lumps formed into which the liquid could only penetrate slowly, so that the Process took one or more days. The vats and their Filter floors strongly attacked by the hot ore and harassed the workers.
Nach der vorliegenden Erfindung läßt sichAccording to the present invention can
nun eine viel schnellere, gründlichere und durch Vermeidung von Handarbeit undnow a much faster, more thorough and by avoiding manual labor and
, Schonung der Apparatur billigere Laugung nach dem als Spüllaugerei zu bezeichnenden Verfahren erzielen. Das Auslaugen von metallhaltigem Gut unter gleichzeitigem Transport des Gutes ist an sich bekannt; dabei werden ohne Rücksicht auf die Entmischung mit Wasser gemischte Erzrückstände unter Druck mit SO2 behandelt, wobei Erz und Wasser durch den Preßdruck des SO2 innig gemischt und entgegen der Schwerkraft befördert werden.To protect the apparatus, achieve cheaper leaching by the process known as rinsing leaching. The leaching of metal-containing material with simultaneous transport of the material is known per se; In doing so, ore residues mixed with water are treated under pressure with SO 2 , regardless of the segregation, with ore and water being intimately mixed by the pressure of the SO 2 and conveyed against gravity.
Offenbar verlangen derartige Verfahren erhebliche Kraftaufwendung und sind wegen der Notwendigkeit der Verwendung von unter Überdruck gasdichter Apparatur dem vorliegenden in offenen Behältern mit vergleichsweise minimalem Kraftaufwand arbeitenden Verfahren wirtschaftlich erheblich unterlegen. Das den Gegenstand der Erfindung bildende Verfahren wird vorteilhaft unter Benutzung der auf der Zeichnung beispielsweise veranschaulichten Vorrichtung folgendermaßen ausgeführt:Apparently, such procedures require considerable effort and are because of Necessity of using pressurized gas-tight apparatus, the present one working in open containers with comparatively minimal effort Process economically considerably inferior. That forming the subject of the invention Method is advantageously illustrated using those illustrated on the drawing, for example Device designed as follows:
Das 300 bis 4000 heiße Röstgut fällt in den trichterförmigen Mischer a, auf welchem es mit solchen Mengen Lauge vorteilhaft mittels eines schräg gerichtete Ausströmöffnungen b besitzenden, in seinem Ende ringförmig gestalteten Zuflußrohres c direkt gemischt wird, daß es unter Vermeidung lästiger Dampf- und Klumpenbildung, sofort abgelöscht und durch die erhitzte Lauge momentan ausgelaugt wird.The 300 to 400 0 hot roasted material falls into the funnel-shaped mixer a, on which it is mixed directly with such amounts of lye, advantageously by means of an inclined outflow openings b , ring-shaped inlet pipe c at its end, that it is avoided while avoiding the formation of steam and lumps , immediately extinguished and momentarily leached out by the heated lye.
Das Gemisch von Röstgut und Lauge passiert dann eine Rinne d, in' der sich die Laugung fortsetzt und aus der es durch den Verteiler β in die Klärbottiche f gelangt. Dieser Verteiler ist ein mit Löchern versehener Schild, der den Flüssigkeitsstrom in einen gleichmäßigen Regen auflöst. Dadurch wird jede Strömung und damit Entmischung des Materials in Korn und Schlamm vermieden, so daß die Trennung von der angereicherten Lauge und das nachherige Auswaschen mit heißem Wasser oder verdünnter Säure durchführbar ist.The mixture of roasted material and lye then passes through a channel d in which the leaching continues and from which it passes through the distributor β into the sewage tank f . This distributor is a perforated shield that breaks the flow of liquid into a steady rain. This avoids any flow and thus segregation of the material into grain and sludge, so that the separation of the enriched lye and subsequent washing with hot water or dilute acid can be carried out.
