Abstract
Zur Nebengewinnung von Schwergutfeinpartikeln wird das Wasser- Sand Gemisch über die Trenneinrichtung geleitet. Bei diesem Verfahren werden die leichten Partikel von den Schwergutfeinpartikeln durch die Kombination aus Schwerkraft, Gefälle und die spezielle Form der Gewebe getrennt. Die Erfindung bewirkt ein besseres Fangverhalten und eine höhere Anreicherung des Schwerminerals. Dies wird dadurch erreicht, dass durch die Durchströmungsöffnungen der einzelnen Gewebe leichte Partikel nach oben und die schwereren Partikel nach unten gespült werden. Die Partikel setzen sich hierbei in den Geweben ab.For secondary production of heavy particle fine particles, the water-sand mixture is passed through the separator. In this process, the light particles are separated from the heavy particle fine particles by the combination of gravity, gradient and the particular shape of the tissues. The invention causes a better fishing behavior and a higher accumulation of heavy minerals. This is achieved by flushing light particles upwards and the heavier particles downwards through the throughflow openings of the individual tissues. The particles settle in the tissues.
Description
Die Erfindung betrifft ein Verfahren zur Gewinnung von feinen Schwergutfeinpartikeln hoher Dichte (> 5 g/cm3). Diese Partikel sind in einem Wasser-Sand-Gemisch mit maximal 8 mm Korngröße vorhanden, welchen einen Waschbehälter(4) durchströmen. Mit diesem Verfahren wird eine vielfach höhere Anreicherung der Schwergutfeinpartikel erzielt.The invention relates to a method for obtaining fine heavy particle fine particles of high density (> 5 g / cm 3 ). These particles are present in a water-sand mixture with a maximum grain size of 8 mm, which flow through a washing container (4). With this method, a much higher enrichment of the heavy particle fine particles is achieved.
Ablagerungen mit Sand, Kies, Schwermineralien und Edelmetallen (z. B. Gold, Silber und andere Elemente) werden im Nass- oder im Trockenabbau mit geeignetem Gerät wie Kettenbagger, Schwimmbagger oder Ähnlichen gewonnen. Die Ablagerungen werden meist trocken vorklassiert, damit Übergrößen des Kieses, auch Überkorn genannt, die Förderbänder oder andere Transportmittel nicht beschädigen.Deposits of sand, gravel, heavy minerals and precious metals (eg gold, silver and other elements) are obtained by wet or dry mining with suitable equipment such as crawler excavators, dredgers or the like. The deposits are usually pre-classified dry, so that oversize of the gravel, also called oversize grain, do not damage the conveyor belts or other means of transport.
Über die Transportmittel gelangt der Rohkies zur Kiesaufbereitung, wo eine weitere Klassierung erfolgt. Beim Nassabbau wird meist das Rohmaterial über eine Entwässerung geleitet, damit es transportfähig wird. Das benannte Verfahren kann auch an diesen Vorrichtungen verwendet werden.The raw gravel is transported to the gravel processing plant where further classification takes place. When wet mining, the raw material is usually passed through a drainage, so that it is transportable. The named method can also be used on these devices.
Der Rohkies gelangt über Transporteinrichtungen zu weiteren Klassiereinrichtungen, wo dieser mit Wasser vermischt wird und weitere Klassifikationen, meist über bekannte Siebvorrichtungen oder Siebmaschinen, durchläuft. Nach dem Absieben großer Bestandteile bleibt als Ergebnis Sand meist kleiner als 2 mm Korngröße (manchmal auch 8 mm Korngröße) übrig. Dieser fällt meist durch eine Siebvorrichtung und wird in einem späteren Arbeitsgang entwässert.The raw gravel arrives via transport facilities to other classification facilities, where it is mixed with water and further classifications, usually on known screening or screening machines, passes. After screening large components remains as a result sand usually smaller than 2 mm grain size (sometimes 8 mm grain size) left. This usually falls through a sieve and is drained in a later operation.

Der Vorteil dieser Erfindung und des Verfahrens gegenüber dem bekannten Verfahren aus der deutschen Patentschrift
Die Gewebe werden oberhalb am höchsten Punkt der Auffangwanne des Gefälles montiert bzw. verankert, um ein Verrutschen zu verhindern. Hierbei kann je nach Gefälle, Wassermenge, Aufgabenstoffe und Aufgabenmenge die Anzahl der aufeinanderliegenden Gewebematten mit Durchströmungsöffnungen (
Die Durchströmungsöffnungen (
Die unteren Gewebe enthalten keine Durchströmungsöffnungen (
Die Durchströmungsöffnungen (
Der Neigungswinkel kann variabel sein, idealerweise zwischen 10° und 25°, um eine optimale Anreicherung zu erreichen.The angle of inclination can be variable, ideally between 10 ° and 25 °, to achieve optimum enrichment.
Das Material, aus dem die Gewebe bestehen, kann Nadelfilz, Kunststoff, Astro Turf, beschichtetes Gewebe oder aus Substanzen bestehen. Eine Durchlässigkeit der verwendeten Gewebe ist unvermeidbar. Von Vorteil sind Gewebe in einer Stärke ab 10 mm. Das Reinigen der Gewebe erfolgt in gesonderten Verfahren. The material of which the fabrics are made may be needle felt, plastic, astro turf, coated fabric or substances. A permeability of the fabrics used is unavoidable. Of advantage are tissues in a thickness from 10 mm. The cleaning of the tissues is done in separate procedures.
