Die Erfindung betrifft ein Schwimmverfahren zur Aufbereitung von Erzen 0. dgl. mittels Öl, Teer, Seife, Kohlenwasserstoffe, Fett 0. dgl. in einer Flüssigkeit sowie eine Vorrichtung zur Durchführung des Verfahrens. Die Erfindung bezweckt eine möglichst vollständige und gleichzeitig eine schnelle Trennung der metallhaltigen Teilchen des Erzes von der Gangart und besonders die Aufbereitung von Roteisenerz.The invention relates to a swimming method for processing ore 0. The like. By means of Oil, tar, soap, hydrocarbons, fat, etc. in a liquid and a device to carry out the procedure. The invention aims to be as complete and simultaneous as possible a rapid separation of the metal-containing particles of the ore from the gangue and especially the processing of red iron ore.

Bei der Aufbereitung von Erzen mittels Ölschwimmverfahrens ist es bekannt, vor dem Eintritt in die Schwimmflüssigkeit Erz und Öl innig miteinander zu verrühren. Bei den bekannten Einrichtungen erfolgt die Mischung mittels Rührvorrichtung.In the processing of ores by means of the oil floating process, it is known before Entering the swimming liquid ore and oil to be intimately mixed with one another. Both known devices, the mixing takes place by means of a stirrer.

Die Erfindung besteht darin, daß die Erze und das Öl usf. beim Eintritt in die Flüssigkeit einer starken Rührung durch einen oder mehrere Flüssigkeitsstrahlen unter hohem Druck ausgesetzt werden. Bei der Anwendung dieses Verfahrens wird ein inniges und gleichmäßiges Mischen erzielt, weil eine feine Verteilung desThe invention consists in that the ores and the oil etc. when entering the liquid strong agitation by one or more jets of liquid under high pressure get abandoned. In applying this procedure, it becomes intimate and even Mixing achieved because of a fine distribution of the

Öles o. dgl. möglich ist.Oil or the like. Is possible.

Wird zu diesem Verfahren Öl verwendet, so kann dieses zuerst zweckmäßig durch Erhitzung in den dampfförmigen Zustand überführt werden, um dadurch den Ölverbrauch möglichst herabzusetzen. Wird dagegen Teer verwendet, welcher sich zur Aufbereitung von Roteisenerz als besonders vorteilhaft erwiesen hat, so kann derselbe in der gewöhnlichen flüssigen Form benutzt werden, weil die Verdampfung von Teer große praktische Schwierigkeiten bereitet. Erz und Öl usw. können zweckmäßig in die Flüssigkeit in der Weise eingeführt werden, daß sie erst beim Eintritt in die Flüssigkeit miteinander gemischt werden.If oil is used for this process, it can first be expediently heated by heating be converted into the vapor state, thereby reducing the oil consumption as much as possible to belittle. If, however, tar is used, which is used to process red iron ore has proven particularly advantageous, it can be in the usual liquid form can be used because the evaporation of tar presents great practical difficulties. Ore and oil etc. may conveniently be introduced into the liquid in such a way as to that they are only mixed with one another when they enter the liquid.

Zur Durchführung dieses Verfahrens kann zweckmäßig eine Einrichtung verwandt werden, die aus einem oder mehreren Injektoren o. dgl. besteht. Mittels des Injektors wird Öl, Teer usw. nud gegebenenfalls auch Erz in einen Behälter eingeführt, der einen verhältnismäßig kleinen Rauminhalt hat, so daß die Wasserstrahlen in dem Behälter ein starkes Rühren 4-5 verursachen können. Aus diesem Behälter fließt dann die Mischung in einen größeren Behälter, in welchem die eigentliche Trennung stattfindet, indem die Erzteilchen zur Oberfläche aufsteigen, während die Bergart zu Boden sinkt.To carry out this procedure, it is advisable to use a facility which consists of one or more injectors or the like. The injector is used to inject oil, tar, etc. nud if necessary also ore introduced into a container, which a proportionately Has small volume, so that the water jets in the container a strong stirring 4-5 can cause. The mixture then flows from this container into a larger one Container in which the actual separation takes place, bringing the ore particles to the surface rise as the mountain species sinks to the ground.

Auf der Zeichnung sind in Fig. 1 und 2 zwei Ausführungsformen einer solchen Einrichtung teilweise im Schnitt dargestellt, während Fig. 3 eine Einzelheit der Einrichtung gemäß Fig. 1 im Schnitt zeigt.In the drawing, in FIGS. 1 and 2, two embodiments of such a device are shown partially shown in section, while FIG. 3 shows a detail of the device according to FIG shows in section.

Claims

The larger container ι is with an edge drain 2 and with a 3 closable by the tap Floor drain 4 provided. The container 1 is immediately followed by a smaller one Container 5, in which the stirring of the mass takes place.

In the embodiment of FIG both the ore and the oil gasified in this case through a single injector nozzle 6 (Fig. 3) introduced into the container 5. A pipe 7 from the ore container 8 opens into the nozzle, further a gas pipe 9 from the retort 10 and then a pipe 11 from the pump 12. In FIG Retort 10 placed in a suitable furnace 13 becomes the oil, the hydrocarbon etc. evaporated. If, on the other hand, the oil or the like is not to be evaporated, the retort 10 with the associated Furnace in discontinuation. A strong jet of water is passed through the nozzle 6 by means of the pump 12 driven, where he partly oil vapor, which flows through the pipe 9, and partly ore with it sucks. In the container 5, the water jet causes a strong agitation, whereby the vaporized oil adheres to the metal-containing particles of the ore. The so mixed one Mass flows into the larger container 1, in which the separation takes place by the Surface layer with the metal-containing ore particles flows out via the drain 2, while the mountain species sinks to the ground and can be removed by 4.

The embodiment shown in Fig. 2 differs from greater performance differs from that described above mainly in that the ore and the oil vapor are separated are introduced into the container 5. The ore comes in from the container 14 immediately the container 5 through the pipe 15, while the oil vapor with the help of a powerful jet of water is introduced through an injector nozzle 16. To achieve the required agitation, is still a water nozzle 17, seen before, which in the container 5 immediately next to the tubes flows out. Otherwise this apparatus operates in the same way as that shown in FIG. The feeding of the ore and the oil through a common injector nozzle offers the particular advantage of a more intimate mixture. '

Godfather nt-A ν Proverbs:

i. Swimming method for reprocessing of ores by means of oil, tar, soap, hydrocarbon, fat or the like due to the strong agitation of the ores with the float when they enter the swimming liquid by one or more jets of liquid emerging under high pressure.

■ 2. Apparatus for carrying out the method according to claim 1, characterized in that the floating means and possibly also the ore-introducing injectors into a small, the actual one Float tank (1) open upstream tank (5).

3. Ausführungsstorm the device according to claim 2, characterized in that A single injector nozzle (6) opens into the container (5) and serves to introduce both the ore and the oil or the like.

4. Embodiment of the device according to claim 2, characterized in that the ore and the oil etc. are introduced separately into the container (5), namely the latter with the help of a jet of water under high pressure, whereby to induce the agitation, another water nozzle opens into the container near the ore supply pipe.
