Description
Verfahren zur Gewinnung von Metallen unmittelbar aus bituminösen Erzen durch Erhitzung unter Luftabschluß Das Hauptpatent 551 92¢ behandelt ein Verfahren, um aus Erzen bituminöser Natur unmittelbar Metalle zu gewinnen. Dabei wird das Erz einer Art Schwelverfahren unterworfen, d. h. auf Temperaturen über 6oo° C unter Luftabschluß erhitzt, wodurch die Metallverbindungen zerlegt und die Metalle freigelegt werden, so daß sie als solche aufbereitet werden können. Es hat sich nun gezeigt, daß dieser Prozeß beschleunigt und erleichtert wird, wenn die Erhitzung unter Luftabschluß in Gegenwart von Wasserdampf erfolgt, vor allen Dingen, wenn das Erz nicht grubenfeucht verarbeitet werden kann. Es ist zwar bekannt, bituminöse Erze der unmittelbaren Einwirkung einer Flamme unter Wasserdampf auszusetzen, jedoch erhält man dabei keine Metalle, sondern Metalloxyde. Es ist auch bekannt, bei der Verwertung des Bitumens aus Kupferschiefer usw. durch abwechselndes Blasen von Luft und Wasserdampf den letzten Teil des Bitumens zu zersetzen und das sich dabei bildende Gas teilweise zur Beheizung des erforderlichen Schachtofens zu benutzen. Bei diesem Verfahren wird zwar eine vollständige Verbrennung des Bitumens, jedoch keine Freilegung von gediegenen Metallen erreicht. Im Gegensatz dazu werden durch die vorliegende Frfindung aus bituminösen Erzen durch Erhitzen unter Luftabschluß in Gegenwart von Wasserdampf Metalle gewonnen. Es genügt, wenn geringd Mengen Wasserdampf zugeleitet werden. Beispielsweise wurden bei der Schwelbehandlung von Mansfelder Kupferschiefer etwa io Gewichtsteile Wasserdampf, bezogen auf die aufgegebene Menge Erz, auf etwa 2oobis 25o° überhitzt und während der Schweldauer von q. Lis 6 Stunden in die Schwelretorte eingeleitet. Das nach der Abkühlung aus der Retorte entnommene Schwelgut zeigte durchweg faden- und kornförmige Kupfer- und sonstige Metallausblühungen, die sich leicht aufbereiten ließen. Das Verfahren hat auch den Vorteil, daß das Gasausbringen vergrößert wird. Gegenüber dem Gasausbringen ohne Zusatz von Wasserdampf konnten etwa i o o/0 im Heizwert gleichwertige Gase mehr gewonnen werden.Process for the extraction of metals directly from bituminous ores by heating in the absence of air. The main patent 551 92 ¢ deals with a process to extract metals directly from ores of a bituminous nature. The ore is thereby subjected to a kind of smoldering process, d. H. to temperatures above 6oo ° C below Exclusion of air heated, causing the metal compounds to break down and the metals exposed so that they can be processed as such. It has now been shown that this process is accelerated and facilitated if the heating is in the absence of air takes place in the presence of water vapor, especially when the ore is not moist in the pit can be processed. Although it is known to be the immediate bituminous ores Exposing to the action of a flame under water vapor, however, does not result in any Metals, but metal oxides. It is also known in the recovery of the bitumen from copper slate etc. by alternately blowing air and water vapor to decompose the last part of the bitumen and the gas that is formed in part to use for heating the required shaft furnace. In this procedure there is a complete combustion of the bitumen, but no exposure of solid metals. In contrast, the present invention from bituminous ores by heating in the absence of air in the presence of water vapor Metals mined. It is sufficient if small amounts of water vapor are supplied. For example, during the smoldering treatment of Mansfeld copper slate, for example 10 parts by weight of water vapor, based on the amount of ore added, to about 20% 25o ° overheated and during the smoldering period of q. Lis 6 hours in the smoldering retort initiated. The carbonized material removed from the retort after cooling showed consistently thread-like and granular copper and other metal efflorescence, which easy to prepare. The method also has the advantage that the gas discharge is enlarged. Compared to gas extraction without the addition of water vapor about i o o / 0 more gases of equivalent calorific value can be obtained.
