Description

Verfahren und Vorrichtung zur Aufbereitung mittels Flotation Zusatz zur Anmeldung: S 106508 VI a/1 c -Auslegeschrift 1252153 Um das Flotationsverfahren ergiebiger zu machen, d. h. das Ausbringen an Nutzmineral zu erhöhen und zugleich den Verfahrensgang zu vereinfachen und wirtschaftlicher zu gestalten, wird der Schwingmühle A nach Patentanmeldung S 106508 VI a/1 c (deutsche Auslegeschrift 1252153) eine an sich bekannte Rührwerksflotation, gegebenenfalls auch eine pneumatische Flotation vorgeschaltet. Hier werden alle bereits frei liegenden Mineralteilchen ausflotiert. Die Flotationstrübe fließt sodann in die Schwingmühle A, die dann nur noch die feineren Verwachsungen aufzuschließen und zu flotieren hat.Method and device for processing by means of flotation additive for registration: S 106508 VI a / 1 c -Auslegeschrift 1252153 To the flotation process to make it more productive, d. H. to increase the output of useful mineral and at the same time The vibratory mill is used to simplify the process and make it more economical A according to patent application S 106508 VI a / 1 c (German Auslegeschrift 1252153) a Agitator flotation known per se, possibly also pneumatic flotation upstream. Here all the mineral particles that are already exposed are floated out. The flotation pulp then flows into the vibrating mill A, which then only has the finer ones Has to open up adhesions and float.

Es kann aber auch gegeben sein, die feinen Verwachsungen durch die vorgeschalteten Rührwerks-oder pneumatischen Zellen als sogenanntes Zwischengut auszuschwimmen und nur dieses Zwischengut in der Schwingmühle aufzuschließen und zu flotieren.But it can also be given by the fine adhesions upstream agitator or pneumatic cells as so-called intermediate material swim out and only open up this intermediate material in the vibrating mill and to float.

Die Zerkleinerung soll bei feinen Verwachsungen möglichst nicht über den für die Freilegung der Mineralindividuen notwendigen Aufschluß durch die Mahlkörper G hinausgehen. Bei der weiteren Ausarbeitung der Erfindung hat es sich gezeigt, daß es nicht immer angebracht ist, die sehr starke Zerkleinerungsfähigkeit der Schwingmühle voll .auszunutzen. Man würde bei C und F ein zu feines. Guterhalten, das schwierig zu filtrieren ist oder sich schlecht absetzt. Es wird daher vorgeschlagen, an Stelle der in der Hauptpatentanmeldung gezeigten verhältnismäßig tiefen Trogform ein abgeflachtes Gefäß zu benutzen, so daß die freigelegten Mineralteilchen auf einem möglichst kurzen Weg an die Trübeoberfläche aufschwimmen können und schnell dem Zerkleinerungsvorgang entzogen werden.The comminution should, if possible, not exceed the fine adhesions the digestion necessary for the exposure of the mineral individuals through the grinding media G go out. In the further elaboration of the invention it has been shown that that it is not always appropriate, the very strong crushing ability of the vibratory mill to fully exploit. At C and F you would be too fine. Keeping it well, that's difficult has to be filtered or does not settle well. It is therefore suggested in place the relatively deep trough shape shown in the main patent application is a flattened one Use vessel so that the exposed mineral particles are as short as possible Can float away to the surface of the sludge and quickly start the crushing process be withdrawn.

Es können eine oder mehrere solcher Gefäßwannen parallel zur Welle des Schwingungsantriebes angebracht und so einander zugeordnet werden, daß die Flotationstrübe von B aus kommend je nach Erfordernis in gleichlaufende Ströme Dl, D2, D, aufgeteilt, durch die Flotationsgefäße I, II, III in Parallelschaltung geführt wird oder bei schwierigem Mineral sämtliche Gefäße hintereinandergeschaltet durchläuft.One or more such vessel troughs can be parallel to the shaft of the vibration drive are attached and assigned to each other so that the flotation pulp Coming from B, depending on requirements, divided into parallel currents Dl, D2, D, is passed through the flotation vessels I, II, III in parallel or at difficult mineral runs through all vessels in series.
