Description
Verfahren zur Konzentration von sulfidischen Erzen nach dem Schwimmverfahren. Die Erfindung betrifft die Konzentration von Mineralien, wie sulfidische Erze u. dgl. (beispielsweise Chalcopyrit mit einer Kieselsäuregangart), nach dem Schwimmverfahren. Es ist bereits bekannt, bei Erzen, die Oxyde oder Karbonate enthalten, als Schwimmmittel Anilinsalze zu verwenden.Process for the concentration of sulphidic ores by the swimming process. The invention relates to the concentration of minerals such as sulfidic ores and. Like. (For example, chalcopyrite with a silicic acid gangue), according to the swimming method. It is already known to use ores containing oxides or carbonates as a floating agent To use aniline salts.
Die Erfindung beruht auf derBeobachtung, daß das Schwimmverfahren beträchtlich verbessert werden kann, wenn man dem Erz-oder Mineralschlamm Toluidin (Aminoxylol) in Form der freien Base entweder für sich oder unter Zusatz anderer Stoffe, die das Schwimmverfahren beschleunigen, zufügt.The invention is based on the observation that the swimming method Can be improved considerably if you add toluidine to the ore or mineral sludge (Aminoxylene) in the form of the free base either by itself or with the addition of others Adding substances that accelerate the swimming process.
Toluidin ist :dem Anilin in seiner technischen Wirkung ganz wesentliich überlegen. Versuche haben gezeigt, daß die Verwendungsmöglichkeit des Anilins in bezug auf seine Anwendung als Schwimmittel ganz außerordentlich :geriing sind. Toluidin besitzt dagegen sowohl vorzüglich sammelnde wie auch schaumbildende Eigenschaften, die es gerade als Schwimmittel ganz besonders geeignet machen.Toluidine is: to aniline in its technical effect very essential think. Experiments have shown that the possibility of using the aniline in with regard to its use as a floating means quite extraordinary: are small. Toluidine on the other hand has excellent collecting as well as foam-forming properties, which make it particularly suitable as a float.
Das Toluidin kann in Form des handelsüblichen Produktes, das aus einer Mischung der verschiedenen Toluidine besteht, Verwendung Anden, und zwar in rohem oder unraffiniertem Zustand.The toluidine can be in the form of the commercial product that consists of a Mixture of different toluidines is made, use Andes, in raw form or unrefined condition.
Das Toluidin kann dem Erz entweder allein oder in Mischung mit anderen Stoffen, welche .das Schwimmen befördern, ein jeder geeigneten Weise zugesetzt werden, so daß es vollkommen gleichmäßig durch den ganzen Erzschlamm hindurch verteilt wird. Die Mischung wird dann dem Schwimmverfahren unterworfen, beispielsweise in einer gewöhnlichen Callowzellc oder in Apparaten, in denen die Luft dem Erzschlamm durch mechanische Rührung einverleibt wird. Bei gewissen Erzschlämmen kann es wünschenswert sein, entweder kleine Mengen von Säuren oder Alkalien je nach ;der Natur des zu behandelnden Erzschlammes zuzufügen. Im allgemeinen soll jedoch keine freie .Säure in irgendwie merklicher Menge zugegen sein, wenn das Toluidin zugefügt wird.The toluidine can be added to the ore either alone or in admixture with others Substances which promote swimming are added in any suitable manner, so that it is distributed perfectly evenly throughout the ore sludge. The mixture is then subjected to the swimming process, for example in a ordinary callow cells or in apparatuses in which the air flows through the ore sludge mechanical agitation is incorporated. It may be desirable for certain ore slurries be either small amounts of acids or alkalis depending on; the nature of the too to be treated ore sludge. In general, however, no free acid be present in some appreciable amount when the toluidine is added.
Bei manchen Erzschlämmen ist es wichtig, nicht nur keine freie Säure anwesend zu haben, sondern man muß auch noch so viel freies Alkali zufügen, daß der Erzschlamm während des Schwimmens eine deutliche alkalische Reaktion anwehst. Kleine Mengen von kaustischem Alkali, wie Natronlauge, oder von Alkalisalzen, wie Soda-, können dann in abgemessenen Mengen zugefügt werden, um dem Schlamm den geeigneten Alkalitätsgrad zu erteilen.With some ore slurries, it is important not just to have no free acid to be present, but one must also add so much free alkali that the ore sludge exhibits a distinct alkaline reaction while swimming. Small amounts of caustic alkali, such as caustic soda, or of alkali salts, such as Soda, can then be added in measured amounts to make the appropriate one to the sludge To give the degree of alkalinity.
Die Tolulidinmenge kann in gewissem Umfang wechseln, beispielsweise zwischen o,2 kg oder weniger und 0,7 kg auf die Tonne Erz (und zwar berechnet auf das Gewicht des Erzes und nicht auf das des Erzschlammes). Die Erfindung ist nachstehend in einem Ausführungsbeispiel beschrieben.The amount of tolulidine can vary to a certain extent, for example between 0.2 kg or less and 0.7 kg per ton of ore (calculated on the weight of the ore and not on that of the ore sludge). The invention is described below in an exemplary embodiment.
5oo Gewichtsteile Erz werden in einer Kugel- oder Achatmühle mit 25o Teilen Wasser gemahlen. Alsdann wird Natronhydroxy d in einer Menge, die etwa i kg auf die Tonne Erz entspricht, und handelsübliches Toluidin entsprechend etwa o,25 kg auf die Tonne Erz zugegeben. Der entstehende Schlamm wird zusammen mit so viel Wasser in eine gröbere pneumatische Callowzelle gebracht, daß ein leicht flüssiger Schlamm entsteht, welcher dann dem .Schwimmverfahren unterworfen wird. Das behandelte Erz enthielt ungefähr 442 Prozent Kupfer. Die erhaltenen Konzentrate enthielten etwa 15,4 Prozent Kupfer, die Ausbeute an Kupfer war etwa 87 Prozent. Das behandelte Erz war ein Utah Kupfererz.500 parts by weight of ore are in a ball or agate mill at 25o Share ground water. Then sodium hydroxide is d in an amount that is about i kg corresponds to the ton of ore, and commercial toluidine corresponds to approx o.25 kg added to the ton of ore. The resulting sludge will go along with so a lot of water put into a coarser pneumatic Callow cell, that a slightly more liquid one Sludge is produced, which is then subjected to the swimming process. That treated Ore contained approximately 442 percent copper. The concentrates obtained contained about 15.4 percent copper; the copper yield was about 87 percent. That treated Ore was a Utah copper ore.
Bei Erzen von dem oben angegebenen Charakter ist die Ver«rendung von Alkali nicht notwendig, aber es hat sich gezeigt, daß seine Verwendung die Ausbeute beträchtlich steigert.In the case of ores of the character given above, the depletion of Alkali not necessary, but its use has been shown to reduce the yield increases considerably.
Nachstehend sind vergleichende Ergebnisse angeführt, .die bei Verwendung
von orto-oder para-Toluidin und Toluidinmischung, die hauptsächlich aus orto- und
para-Toluidin bestand, in einer Weise erhalten worden sind, die etwa dem oben angegebenen
Beispiel entspricht.
Das Toluidin kann allein verwendet werden, um das .Schwimmverfahren zu beschleunigen, und es werden hierbei hohe Konzentrationsgra,de erzielt.The toluidine alone can be used to complete the swimming process to accelerate, and there are high levels of concentration, de achieved.
Die entstehenden Konzentrate können leichter durch Filtration getrennt werden als die gewöhnlichen Konzentrate, die bei Verwendung von Ölen als Schwimmittel erhalten werden. Die Wirkung des Toluidnn kann indessen geändert oder unterstützt werden, indem man andere Stoffe (wie Öle oder nichtölige Stoffe) hinzufügt, welche das Schwimmen beschleunigen und die Wirkung des Toluiidins nicht ungünstig beeinflussen.The resulting concentrates can more easily be separated by filtration are considered the ordinary concentrates that come with the use of oils as flotation can be obtained. The action of the toluene can, however, be modified or enhanced by adding other substances (such as oils or non-oily substances) which Accelerate swimming and do not adversely affect the effects of toluiidine.
Das Toluidin kann in der Mühle eingeführt werden, in der das Erz gemahlen wird. Es kann aber auch in jeder geeigneten Weise anderweitig in dem Erzschlamm eingeführt werden, beispielsweise indem man es in den Erzschlamm tropft, bevor er in die Schwimmzelle eintritt, oder indem man es zuerst in heißem Wasser digeriert und das Produkt rnit dem Erzschlamm gerade, bevor er in die Schwimmzelle eintritt, mischt.The toluidine can be introduced into the mill in which the ore is ground will. However, it can also be present elsewhere in the ore sludge in any suitable manner be introduced, for example by dripping it into the ore sludge before it entering the swim cell, or by first digesting it in hot water and the product with the ore sludge just before it enters the swimming cell, mixes.
