Description
Verfahren zur Aufbereitung von Erzen nach einem Schwimmverfahren. Es ist bekannt, Luft oder sonstige. Gase bei Schwimmverfahren zur Erzeugung von Bläschen ins Scheidebad einzuführen, die im Scheidebade aufsteigen und vermöge ihrer Adhäsionskraft gewisse Mineralien aus Erzgemischen an die Oberfläche heben. Die Gase werden dabei durch Druckluft oder mechanische Mittel möglichst verteilt. Es ist ferner bekannt, Luft oder sonstige Gase dadurch auf das ganze Scheidebad zu verteilen, daß man sie durch ein Filter in das Scheidebad treten läßt. Ebenso wird die Verwendung von Injektordüsen für Schwimmvorrichtungen als bekannt vorausgesetzt.Process for processing ores using a floating process. It is known to be air or otherwise. Gases used in swimming processes to generate To introduce vesicles into the bath, which rise in the bath and by virtue of them Adhesive strength to lift certain minerals from ore mixtures to the surface. the Gases are distributed as much as possible by compressed air or mechanical means. It is also known to cause air or other gases to flow into the entire separation bath distribute so that they can pass through a filter into the separating bath. Likewise will the use of injector nozzles for swimming devices is assumed to be known.
Bei allen bekannten Verfahren erfolgt die Luftverteilung in mehr oder weniger groben Bläschen. Eingehende Versuche haben nun gezeigt, daß die Verteilung der Blasen auf den ganzen Querschnitt des Scheidebades um so besser und allgemeiner ist, je kleiner die Bläschen gehalten werden können, und daß -dementsprechend die Einwirkung auf die Mineralteilchen eine bessere ist, wie anderseits die Ausnutzung des Gases eine weit höhere wird.In all known methods, the air is distributed in more or more less coarse vesicles. Detailed tests have now shown that the distribution the blisters on the whole cross-section of the vaginal bath are all the better and more general is, the smaller the bubbles can be kept, and that-accordingly the The effect on the mineral particles is better, as is the utilization on the other hand of the gas is much higher.
,je geringer die Gasmenge ist, die im Scheidebade arbeitet, desto ruhiger erfolgt der Scheidevorgang, desto besser die Scheidung. Die Verwendung von Tuch-, Drahtgeweben usw. führt eine feine Verteilung der Gasbläschen nicht vollständig herbei, da sich an der Austrittläche das Gas wieder zu größeren Blasen vereinigt; ehe es den erforderlichen Auftrieb hat. Die Erfindung besteht darin, daß Luft oder Gas in dem inneren, Druckwasser' in dem äußeren Rohr der doppelwandigen Düse geführt und gegen eine senkrecht .zur Düse angebrachte Platte geschleudert werden, wodurch feine bis feinste Luft- bzw. Gasbläschen erzeugt werden, die sich auf das Scheidebad verteilen., The lower the amount of gas that works in the separator, the more The quieter the divorce, the better the divorce. The usage of Cloth, wire mesh, etc. do not fully distribute the gas bubbles because the gas reunites to form larger bubbles at the exit surface; before it has the necessary buoyancy. The invention is that air or Gas in the inner 'pressurized water' is guided in the outer tube of the double-walled nozzle and thrown against a plate attached perpendicular to the nozzle, whereby fine to very fine air or gas bubbles are generated, which affect the separating bath to distribute.
Die Zeichnung veranschaulicht eine zur Ausführung des Verfahrens geeignete Vorrichtung, und zwar eine in dem Boden des Scheidebades angeordnete Doppeldüse, in deren innerem Rohr a durch eine Öffnung Luft strömt, während das äußere Rohr b mit seiner Spitze über die Spitze des inneren Rohres hinaussteht und Wasser unter Druck austreten und gegen eine senkrecht gegen die Öffnung gerichtete Platte c strömen läßt. Hierbei bewirkt das Druckwasser ein derartiges Zerschellen des Gases, daß es sich in- Form feinster Bläschen auf das ganze Scheidebad verteilt, die ruhig im Scheidebad aufsteigen. . Dasselbe wird erreicht, wenn an Stelle des Druckwassers die. Erztrübe selbst durch die äußere Düse in das Scheidebad eingeführt wird. Als Nebenzweck wird dabei schon beim Eintritt ins Scheidebad eine innige Berührung der Erzteilchen mit dem Gemisch von Gasbläschen erzielt.The drawing illustrates one suitable for carrying out the method Device, namely a double nozzle arranged in the bottom of the separating bath, in whose inner tube a air flows through an opening, while the outer tube b with its tip protruding over the tip of the inner tube and water under it Exit pressure and flow against a plate c directed perpendicularly towards the opening leaves. Here, the pressurized water causes the gas to burst in such a way that it is distributed in the form of the finest vesicles over the entire vaginal bath, the calm ascend in the separating bath. . The same is achieved if in place of the pressurized water the. Ore slurry itself is introduced into the separating bath through the outer nozzle. as A secondary purpose is an intimate touch of the person as soon as they enter the bath Ore particles achieved with the mixture of gas bubbles.
