Description
Schwimmverfahren zur Gewinnung von Mineralien aus Gemischen mit Einschlagen, Zuleitung oder Entwicklung von Luft oder Gasen. Es ist bekannt, in Schwimmvorrichtungen mit oder ohne Schwimmittelzusatz Luft oder Gas ununterbrochen und gleichmäßig aufsteigen zu lassen bzw. gleichmäßig in die Erztrübe einzuschlagen. Die Folge ist, daß bei dem Aufsteigen der Luft- oder Gasbläschen, das dem Grundsatz der Schwimmverfahren entsprechend in möglichster Dichte erfolgen soll, die Gesamtheit der das Mineralgemisch bildenden Bestandteile einen Auftrieb erhält, der sich nicht allein auf die an den Gasbläschen anhaftenden Mineralien beschränkt, sondern auch auf die Gangartteilchen einwirkt.Swimming process for the extraction of minerals from mixtures with impact, Supply or development of air or gases. It is known in swimming devices rise continuously and evenly with or without the addition of air or gas to leave or to beat evenly into the ore slurry. The result is that at the rise of the air or gas bubbles, the principle of the swimming procedure The entirety of the mineral mixture should take place accordingly in the greatest possible density constituent elements receives a boost that is not limited to the Gas bubbles are limited to adhering minerals, but also to the gangue particles acts.
Die Erfindung beruht darin, daß in Abständen, die von der in jedem Fall erforderlichen Stärke der Blasenbildung, der Art und Feinheit des Erzgemisches abhängig sind, eine Änderung in. der Dichte der Blasenwolken und in der Feinheit der Gasblasen vorgenommen wird, durch welche eine zeitweise Beruhigung des Schwimmbades erfolgt. Während dieser ruhigeren Arbeit finden die anhaftenden Teilchen Gelegenheit, zu Boden zu sinken. Eine Abart des Veifahrens besteht darin, das Aufsteigen der Gasblasen ganz zu unterbrechen. Es erweist sich dies besonders in den Fällen als günstig, in denen das Gemisch auf große Feinheit zerkleinert werden mußte.The invention resides in the fact that at intervals that are determined by the in each Case required strength of the bubble formation, the type and fineness of the ore mixture are dependent on a change in the density of the bubble clouds and in the fineness the gas bubbles are made, through which a temporary calming of the swimming pool he follows. During this quieter work, the adhering particles find the opportunity to to sink to the ground. A variant of the process consists in ascending the To completely interrupt gas bubbles. It proves this especially in the cases as favorable, in which the mixture had to be crushed to great fineness.
Weitere Abarten des Verfahrens bestehen darin, daß während der Verminderung oder Unterbrechung der Gas- bzw. Lufteinwirkung auch die Verrührung und Zuführung des Erzgemisches eingestellt oder vermindert wird, während der Einwirkung der Gase aber besonders lebhaft gestaltet wird.Other variations of the method are that during the reduction or interruption of the action of gas or air, including stirring and supply of the ore mixture is stopped or decreased during the action of the gases but is designed to be particularly lively.
Es ist offensichtlich, daß sich die Gangartteilchen um so besser absetzen, in je größerer Ruhe die Trübe gehalten wird.It is obvious that the gait particles settle the better the more calm the turbidity is kept.
Der Vorzug des Verfahrens beruht darin, daß innerhalb der Ruhepausen bzw. während der weniger lebhaften Bewegung im Schwimmbehälter sich nicht nur das Absinken der nicht absorbierbaren Gemischteilchen leichter gestaltet, sondern auch der bereits über der Oberfläche des Schwimmbades gebildete Schaum die mitgerissenen Teilchen leichter fallen lassen kann, während bei gleichmäßig starkem Gasauftrieb stark beladene und infolgedessen schwach auftreibende Gasblasen durch eine übergroße Menge absinkender Gangartteilchen abwärts gedrückt werden und durch die neben ihnen lebhafter aufsteigenden Gasblasen infolge Abtriebs einen Teil der anhaftenden Mineralteilchen verlieren, die dann zu Boden sinken.The advantage of the method is that within the rest periods or during the less lively movement in the swimming pool, not only that Sinking of the non-absorbable mixture particles made easier, but also the foam already formed over the surface of the swimming pool the entrained Particles can fall more easily, while with a steadily strong gas buoyancy heavily loaded and consequently weakly upwelling gas bubbles through an oversized one Amount of descending gait particles are pushed down and by the next to them more vigorously rising gas bubbles as a result of the removal of part of the adhering mineral particles lose, which then sink to the ground.
