- mindestens einen Magnetseparator sowie

Die Erfindung betrifft weiterhin eine Verwendung einer solchen Vorrichtung.The invention further relates to a use of such a device.
Im Bergbau werden bei der Abtrennung von Wertstoffen von Mineralien unterschiedlichste Trennverfahren eingesetzt. Zu den wichtigsten Trennverfahren gehört dabei die magnetische Separation, bei der die magnetischen Eigenschaften eines Bestandteils des Minerals als Trennkriterium genutzt werden. Aber auch eine Flotation wird häufig zur Abtrennung von Wertstoffen von Mineralien eingesetzt, wobei der abzutrennende Stoff hydrophob ist oder gezielt hydrophobisiert wird.In mining, the separation of valuable materials from minerals a variety of separation processes are used. One of the most important separation processes involves magnetic separation, in which the magnetic properties of a constituent of the mineral are used as a separation criterion. But a flotation is often used for the separation of recyclables of minerals, wherein the material to be separated is hydrophobic or is specifically hydrophobized.
Insbesondere bei der Aufbereitung von Eisenerzen kommen beide Trennverfahren nacheinander zum Einsatz.In particular, in the treatment of iron ores, both separation methods are used successively.
Magnetseparatoren sind bereits bekannt und werden insbesondere in der Bergbauindustrie und der Metallindustrie, aber auch in anderen Industriezweigen eingesetzt. So beschreibt die
Weitere Typen von Magnetseparatoren, die mit umlaufenden magnetbestückten Bändern oder magnetischen Wanderfeldern arbeiten, sind ebenfalls bekannt.Other types of magnetic separators that use circulating magnetized tapes or traveling magnetic fields are also known.
Die Flotation ist ein physikalisches Trennverfahren zur Trennung feinkörniger Feststoffgemenge, wie beispielsweise von Erzen und Gangart, in einer wässrigen Aufschlämmung bzw. Suspension mit Hilfe von Luftbläschen aufgrund einer unterschiedlichen Oberflächenbenetzbarkeit der in der Suspension enthaltenen Partikel. Sie wird zur Aufbereitung von Bodenschätzen und bei der Verarbeitung von vorzugsweise mineralischen Stoffen mit einem niedrigen bis mittleren Gehalt an einer Nutzkomponente bzw. eines Wertstoffs verwendet, beispielsweise in Form von Nichteisenmetallen, Eisen, Metallen der seltenen Erden und/oder Edelmetallen sowie nichtmetallischen Bodenschätzen. Generell ist eine Anwendung der Flotation aber auch auf anderen technischen Gebieten, wie beispielsweise der Abwasseraufbereitung, bereits hinreichend bekannt.Flotation is a physical separation process for separating fine-grained mixtures of solids, such as ores and gangue, in an aqueous slurry by means of air bubbles due to a different surface wettability of the particles contained in the suspension. It is used for the treatment of mineral resources and in the processing of preferably mineral substances with a low to moderate content of a useful component or a valuable material, for example in the form of non-ferrous metals, iron, metals of rare earths and / or precious metals and non-metallic mineral resources. In general, an application of the flotation but also in other technical fields, such as wastewater treatment, already well known.
Die
Bei der pneumatischen Flotation wird generell eine mit Reagenzien versetzte Suspension aus Wasser und feinkörnigem Feststoff über mindestens eine Düsenanordnung in eine Flotationskammer eingebracht. Die Reagenzien sollen bewirken, dass insbesondere die wertvollen, bevorzugt abzutrennenden Partikel bzw. Wertstoffpartikel in der Suspension hydrophob ausgebildet werden. Meist werden als Reagentien Xanthate eingesetzt, insbesondere um sulfidische Erzpartikel selektiv zu hydrophobisieren. Gleichzeitig mit der Suspension wird der mindestens einen Düsenanordnung Gas, insbesondere Luft, zugeführt, das mit den hydrophoben Partikeln in der Suspension in Berührung kommt. Die hydrophoben Partikel haften an sich bildenden Gasbläschen an, so dass die Gasbläschen-Gebilde, auch Aeroflocken genannt, aufschwimmen und an der Oberfläche der Suspension das Schaumprodukt bilden. Das Schaumprodukt wird in einen Sammelbehälter ausgetragen und üblicherweise noch eingedickt.In pneumatic flotation, a suspension of water and fine-grained solid mixed with reagents is generally introduced into a flotation chamber via at least one nozzle arrangement. The purpose of the reagents is to ensure that, in particular, the valuable particles or valuable material particles, which are preferably to be separated off, are rendered hydrophobic in the suspension. In most cases, xanthates are used as reagents, in particular to selectively hydrophobize sulfidic ore particles. Simultaneously with the suspension, the At least one nozzle arrangement gas, in particular air, supplied, which comes into contact with the hydrophobic particles in the suspension. The hydrophobic particles adhere to forming gas bubbles, so that the gas bubble structures, also called aeroflocs, float and form the foam product on the surface of the suspension. The foam product is discharged into a collecting container and usually thickened.
Die Qualität des Schaumprodukts bzw. der Trennerfolg des Verfahrens der Flotation ist unter anderem von der Kollisionswahrscheinlichkeit zwischen einem hydrophoben Partikel und einem Gasbläschen abhängig. Je höher die Kollisionswahrscheinlichkeit, desto größer ist die Anzahl an hydrophoben Partikeln, die an einem Gasbläschen anhaften, an die Oberfläche aufsteigen und zusammen mit den Partikeln das Schaumprodukt bilden.The quality of the foam product or the separation efficiency of the flotation process depends inter alia on the probability of collision between a hydrophobic particle and a gas bubble. The higher the probability of collision, the greater the number of hydrophobic particles that adhere to a gas bubble, rise to the surface and together with the particles form the foam product.
Spezifische Ausbildungen der pneumatischen Flotation sind bspw. die Entspannungsflotation oder Säulenflotation.Specific embodiments of the pneumatic flotation are, for example, the relaxation flotation or column flotation.
Bei säulenartig ausgebildeten Flotationszellen, bei welchen ein Durchmesser der Flotationskammer um ein Vielfaches geringer ist als deren Höhe, ist der Weg, welchen ein Gasbläschen in der Suspension bzw. der Flotationskammer zurücklegen muss, um an die Oberfläche der Suspension zu gelangen, besonders groß. Aufgrund des besonders langen Weges entstehen in der Suspension besonders große Gasblasen. Dadurch sinken der spezifische Austrag an Wertstoffpartikeln aus der Suspension und somit auch der Wirkungsgrad der Flotationsvorrichtung.In columnar flotation cells in which a diameter of the flotation chamber is many times smaller than its height, the path which a gas bubble must travel in the suspension or the flotation chamber in order to reach the surface of the suspension is particularly large. Due to the particularly long way, particularly large gas bubbles are formed in the suspension. As a result, the specific discharge of valuable material particles from the suspension and thus also the efficiency of the flotation device decrease.
Bei sogenannten Hybridflotationszellen, die eine Kombination einer pneumatische Flotationszelle mit einer säulenartig ausgebildeten Flotationszelle darstellen, werden Feinanteile mit Partikeldurchmessern im Bereich von 20 µm und weniger besonders gut abgeschieden.In so-called hybrid flotation cells, which represent a combination of a pneumatic flotation cell with a columnar flotation cell, fines with particle diameters in the range of 20 microns and less are deposited particularly well.
Die Rührwerksflotation basiert zwar ebenfalls auf der Einbringung von Gasblasen in den Flotationsprozess, wird jedoch in der Regel nicht als pneumatisches Flotationsverfahren bezeichnet. Bei letzterer Ausführungsform der Flotation erfolgt die Erzeugung gewünschter Gasblasen, insbesondere gewünschter Größenverteilungen der Gasblasen, durch ein Rührwerk. Zur Durchführung eines solchen Verfahrens geeignete Flotationsvorrichtungen werden daher auch u.a. als Rührwerkszellen bezeichnet.While agitator floatation is also based on the introduction of gas bubbles into the flotation process, it is not commonly referred to as a pneumatic flotation process. In the latter embodiment of the flotation, the production of desired gas bubbles, in particular desired size distributions of the gas bubbles, takes place by means of an agitator. For carrying out such a method suitable flotation devices are therefore also u.a. referred to as agitator cells.
Die obigen Flotationsverfahren werden in der Regel mittels entsprechender Flotationsvorrichtungen, insbesondere Flotationszellen, ausgeführt.The above flotation processes are generally carried out by means of corresponding flotation devices, in particular flotation cells.
Üblicherweise erfolgt eine Flotation derart, dass der Wertstoff nach oben mit dem Schaum ausgetragen wird. Allerdings kann eine Flotationszelle auch umgekehrt betrieben werden, wobei der Wertstoffstrom enthaltend magnetische und/oder magnetisierbare Partikel am unteren Auslauf aus der Flotationszelle ausgeschleust wird und nicht-magnetische und/oder nicht-magnetisierbare Partikel, die sogenannten Abfallstoffe, über den Schaum nach oben aus der Flotationskammer ausgetragen werden. Diese Art der Flotation, auch "Reverse Flotation genannt, wird insbesondere bei der Aufbereitung von Eisenerzen eingesetzt.Usually, a flotation is carried out such that the recyclable material is discharged upwards with the foam. However, a flotation cell can also be operated vice versa, wherein the recyclable material containing magnetic and / or magnetizable particles at the lower outlet is discharged from the flotation cell and non-magnetic and / or non-magnetizable particles, the so-called waste, on the foam up out of the Flotationskammer be discharged. This type of flotation, also called "reverse flotation", is used in particular in the treatment of iron ores.
Die beiden genannten Trennverfahren, d.h. die Magnetseparation und die Flotation, benötigen jeweils zu ihrer Realisierung einen minimalen volumen- oder massebezogenen Maschinen- bzw. Prozessdurchsatz sowie eine bestimmte Anlagenaufstellfläche, wobei die Maschinengrundflächen und weiterhin Mischbehälter zur chemischen Konditionierung der Suspension, z.B. zur Zugabe von hydrophobisierenden Flotationschemikalien, vorzusehen sind. Zudem wird eine Grundfläche für das Verlegen von Rohrleitungen und das Aufstellen von Pumpen benötigt, die die unterschiedlichen Anlagenteile der Magnetseparation mit denen der Flotation verbinden.The two mentioned separation processes, ie the magnetic separation and the flotation, each require for their realization a minimum volume or mass related machine or process throughput and a certain plant footprint, the machine base and further mixing vessel for chemical conditioning of the suspension, eg for the addition of hydrophobizing Flotation chemicals to be provided. In addition, a base for the laying of pipelines and the installation of pumps is needed, which connect the different parts of the system of magnetic separation with those of the flotation.
Es ist Aufgabe der Erfindung, eine kostengünstige und einfach zu betreibende Vorrichtung zum Abtrennen magnetischer und/oder magnetisierbarer Partikel von einer Suspension bereitzustellen. Weiterhin ist es Aufgabe der Erfindung, eine vorteilhafte Verwendung einer derartigen Vorrichtung vorzusehen.It is an object of the invention to provide an inexpensive and easy-to-operate device for separating magnetic and / or magnetizable particles from a suspension. It is another object of the invention to provide an advantageous use of such a device.
Die Erfindung wird für die Vorrichtung zum Abtrennen magnetischer und/oder magnetisierbarer Partikel von einer Suspension enthaltend weiterhin nicht-magnetische und/oder nicht-magnetisierbare Partikel gelöst, indem sie umfasst:
- mindestens einen Magnetseparator sowie
- mindestens eine Flotationszelle,
- at least one magnetic separator as well
- at least one flotation cell,
Aufgrund der vertikalen Stapelung von Magnetseparatoren und Flotationszellen zur Durchführung der unterschiedlichen Trennverfahren wird der hohe Platzbedarf, den heutige Anlagen umfassend derartige unterschiedliche Trennaggregate in der Regel benötigen, drastisch gesenkt. Das erforderliche Rohrleitungssystem zur Verbindung von Magnetseparator(en) und Flotationszelle(n) kann deutlich vereinfacht und verkürzt aufgebaut und Pumpen für den Transport der Suspension eingespart werden. Dies senkt die Kosten des Betriebs der Vorrichtung signifikant und vereinfacht deren Überwachung durch Bedienpersonal.Due to the vertical stacking of magnetic separators and flotation cells for carrying out the different separation processes, the large space required by today's systems comprising such different separation units is generally drastically reduced. The required piping system for connecting the magnetic separator (s) and flotation cell (s) can be significantly simplified and shortened and pumps for the transport of the suspension can be saved. This significantly reduces the cost of operating the device and simplifies its monitoring by operators.
Insbesondere überlagern sich die vertikale Mittelachse eines Magnetseparators und einer Flotationszelle. Auch eine Überlappung der erforderlichen Grundfläche eines Magnetseparators und einer erforderlichen Grundfläche für eine Flotationszelle von mindestens 50 % hat sich bewährt.In particular, the vertical central axis of a magnetic separator and a flotation cell overlap. Also, an overlap of the required base of a magnetic separator and a required footprint for a flotation cell of at least 50% has been proven.
Dabei hat es sich besonders bewährt, wenn die mindestens eine Flotationszelle vertikal oberhalb des mindestens einen Magnetseparators angeordnet ist. Insbesondere ist eine Flotationszelle senkrecht oberhalb eines Magnetseparators angeordnet ist. Die Strömungsverhältnisse in Flotationszellen können derart eingestellt werden, dass sich in der Suspension ausbildende Agglomerate aus magnetischen und/oder magnetisierbaren Partikeln, d.h. Wertstoffpartikeln, und weiterhin nicht-magnetischen und/oder nicht-magnetisierbaren Partikeln, d.h. Abfallstoffen, zerstört werden. Dies erfolgt insbesondere durch eine turbulente Strömungsführung und/oder eine ausreichend hohe Strömungsgeschwindigkeit in der Flotationszelle. Der aus der Flotationszelle kommende Wertstoffstrom lässt sich aufgrund der geringen Anzahl an enthaltenen Agglomeraten besonders effizient in einem nachgeschalteten, unterhalb angeordneten Magnetseparator verarbeiten, wobei der Wertstoffstrom ohne die Hilfe von Pumpen und damit ohne zusätzlichen Energieaufwand in Richtung des Magnetseparators abfließen kann.It has proven particularly useful if the at least one flotation cell is arranged vertically above the at least one magnetic separator. In particular, a flotation cell is arranged vertically above a magnetic separator. The flow conditions in flotation cells can be adjusted so that agglomerates forming in the suspension of magnetic and / or magnetizable particles, i. Recyclable particles, and further non-magnetic and / or non-magnetizable particles, i. Waste materials are destroyed. This is done in particular by a turbulent flow guidance and / or a sufficiently high flow velocity in the flotation cell. Due to the small number of agglomerates contained, the recyclable material flow coming from the flotation cell can be processed particularly efficiently in a downstream, below arranged magnetic separator, wherein the valuable material flow can flow away without the aid of pumps and thus without additional energy expenditure in the direction of the magnetic separator.
Sofern einer Bildung von Agglomeraten durch die o.g. Maßnahmen in der mindestens einen Flotationszelle nicht ausreichend entgegengewirkt werden kann, hat es sich bewährt, zwischen der mindestens einen Flotationszelle und dem mindestens einen Magnetseparator eine Leiteinrichtung vorzusehen, die eine hohe Scherkraft auf den aus der mindestens einen Flotationszelle kommenden Wertstoffstrom ausübt und enthaltene Agglomerate zerstört und damit die Abtrennung von in den Agglomeraten noch enthaltenen Abfallstoffen begünstigt. Bevorzugt handelt es sich um eine Leiteinrichtung, die eine turbulente Strömung des Wertstoffstroms erzeugt. Als Leiteinrichtung kann demnach beispielsweise eine Einrichtung dienen, die starke Verwirbelungen im Wertstoffstrom erzeugt, diesen in eine Drallbewegung versetzt oder stark beschleunigt.If formation of agglomerates by the o.g. Measures in the at least one flotation cell can not be sufficiently counteracted, it has been proven to provide a guide between the at least one flotation cell and the at least one magnetic separator, which exerts a high shear force on coming from the at least one flotation cell material flow and destroyed agglomerates and destroyed thus favors the separation of waste materials still contained in the agglomerates. Preferably, it is a guide that generates a turbulent flow of the recyclable material stream. Accordingly, a device can serve as a guide, for example, which generates strong swirling in the material flow, displaces it into a swirling motion or greatly accelerates it.
Bevorzugt ist mindestens ein Tamponventil zwischen der Flotationszelle und dem Magnetseparator angeordnet, durch welches der Wertstoffstrom von der Flotationszelle in den Magnetseparator überführbar ist. Das Tamponventil ermöglicht eine Vergleichmäßigung des Wertstoffstroms und seiner Verteilung im Aufgabebereich des Magnetseparators.At least one tampon valve is preferably arranged between the flotation cell and the magnetic separator, through which the material flow from the flotation cell into the magnetic separator is convertible. The tampon valve allows a homogenization of the recyclable material flow and its distribution in the application area of the magnetic separator.
Alternativ kann der mindestens eine Magnetseparator aber auch vertikal oberhalb der mindestens einen Flotationszelle angeordnet sein. Insbesondere ist ein Magnetseparator senkrecht oberhalb einer Flotationszelle angeordnet. Auch in diesem Fall werden die Vorteile eines minimalen Platzbedarfs und deutlich reduzierter Kosten für Infrastruktur und Betrieb erreicht.Alternatively, however, the at least one magnetic separator can also be arranged vertically above the at least one flotation cell. In particular, a magnetic separator is arranged vertically above a flotation cell. In this case too, the advantages of a minimum space requirement and significantly reduced costs for infrastructure and operation are achieved.
Sofern eine Bildung von Agglomeraten im Wertstoffstrom auftritt, der aus dem Magnetseparator in Richtung der Flotationszelle geleitet wird, hat es sich ebenfalls bewährt, zwischen dem mindestens einen Magnetseparator und der mindestens einen Flotationszelle eine Leiteinrichtung vorzusehen, die eine hohe Scherkraft auf den aus dem mindestens einen Magnetseparator kommenden Wertstoffstrom ausübt und enthaltene Agglomerate zerstört und damit die Abtrennung von in den Agglomeraten noch enthaltenen Abfallstoffen fördert. Bevorzugt handelt es sich um auch hier eine Leiteinrichtung, die eine turbulente Strömung des Wertstoffstroms erzeugt. Als Leiteinrichtung kann demnach beispielsweise eine Einrichtung dienen, die starke Verwirbelungen im Wertstoffstrom erzeugt, diesen in eine Drallbewegung versetzt oder stark beschleunigt.If a formation of agglomerates occurs in the material flow, which is passed from the magnetic separator in the direction of the flotation cell, it has also proven to provide a guide between the at least one magnetic separator and the at least one flotation cell, which has a high shear on the at least one Magnetseparator forthcoming material flow exerts and destroys contained agglomerates and thus promotes the separation of waste contained in the agglomerates. Preferably, it is also here a guide that generates a turbulent flow of the recyclable material flow. Accordingly, a device can serve as a guide, for example, which generates strong swirling in the material flow, displaces it into a swirling motion or greatly accelerates it.
Bevorzugt umfasst die mindestens eine Flotationszelle mindestens einen Ejektor zum Eindüsen des mindestens einen Wertstoffstroms in eine Flotationskammer der Flotationszelle, wobei der Magnetseparator über das Rohrleitungssystem mit dem mindestens einen Ejektor verbunden ist.Preferably, the at least one flotation cell comprises at least one ejector for injecting the at least one recyclable material stream into a flotation chamber of the flotation cell, wherein the magnetic separator is connected to the at least one ejector via the piping system.
Sofern die Menge an Wertstoff nicht ausreicht, ein nachgeschaltetes Aggregat mit dem benötigten Wertstoffstrom pro Zeiteinheit zu versorgen, können bei Bedarf die Wertstoffströme mehrerer Flotationszellen einem einzelnen Magnetseparator zugeführt werden oder die Wertstoffströme mehrerer Magnetseparatoren einer einzelnen Flotationszelle zugeführt werden.If the amount of valuable material is insufficient to supply a downstream aggregate with the required valuable stream per unit of time, if necessary, the valuable streams of several flotation cells can be fed to a single magnetic separator or the valuable streams of several Magnetseparatoren a single flotation cell are supplied.
Der mindestens eine Magnetseparator ist bevorzugt durch einen eingangs beschriebenen Trommelseparator gebildet. Die mindestens eine Flotationszelle ist bevorzugt durch eine eingangs beschriebene Hybridflotationszelle gebildet.The at least one magnetic separator is preferably formed by a drum separator described above. The at least one flotation cell is preferably formed by a hybrid flotation cell described above.
Insbesondere ist es von Vorteil, wenn der mindestens eine Magnetseparator und die mindestens eine Flotationszelle in einer gemeinsamen Trag- und/oder Gehäuseeinrichtung vertikal übereinander gestapelt angeordnet sind. Dies erleichtert die Anordnung der Trennaggregate zueinander und die Installation des Rohrleitungssystems auf engem Raum.In particular, it is advantageous if the at least one magnetic separator and the at least one flotation cell are arranged vertically stacked in a common support and / or housing device. This facilitates the arrangement of the separation units to each other and the installation of the piping system in a small space.
Die Verwendung einer erfindungsgemäßen Vorrichtung zur Abtrennung von magnetischen und/oder magnetisierbaren Erzpartikeln von einer Suspension, insbesondere Eisenerzsuspension, enthaltend weiterhin nicht-magnetische und/oder nicht-magnetisierbare Partikel, ist ideal.The use of a device according to the invention for the separation of magnetic and / or magnetizable ore particles from a suspension, in particular iron ore suspension, containing furthermore non-magnetic and / or non-magnetizable particles, is ideal.
