Description

Verfahren zum Trennen von Kupfer und Wismut Die Gewinnung der Metalle durch Verflüchtigung oder Destillation und ihre Reinigung auf die gleiche Weise ist bekannt. Als Heizquelle dienen in solchen Fällen gewöhnlich elektrische üfen.Process for separating copper and bismuth The extraction of the metals by volatilization or distillation and their purification in the same way is known. In such cases, electric heaters are usually used as the heat source.

Es ist ferner bekannt, Metalle durch Vakuumdestillation von ihren Verunreinigungen zu befreien und voneinander zu trennen.It is also known to use vacuum distillation of their metals To free impurities and to separate them from one another.

Einen größeren Eingang hat jedoch die Vakuumdestillation bei höheren Temperaturen, insbesondere auch für die Metallraffination, bisher in die Technik noch nicht gefunden. Das liegt wohl in erster Linie daran, daß es sich bei diesen Verfahren um recht hohe Temperaturen handelt und daß die üblichen Baustoffe dem gemeinsamen Angriff der verflüchtigten Stoffe und der hohen Temperatur nicht lange widerstehen. Nach verhältnismäßig kurzer Betriebszeit leidet die Vakuumabdichtung, und das Verfahren ist dann nicht mehr wirtschaftlich durchführbar.However, vacuum distillation has a larger input at higher ones Temperatures, especially for metal refining, have so far been used in the technology not found yet. This is primarily due to the fact that these Process is quite high temperatures and that the usual building materials the joint attack of the volatilized substances and the high temperature did not last long resist. After a relatively short operating time, the vacuum seal suffers, and the process is then no longer economically feasible.

Um diese Schwierigkeiten bei der Trennung des Wismuts vom Kupfer im Vakuum zu beseitigen, wird erfindungsgemäß das Verfahren in :einer Anlage durchgeführt, in welcher das das kupferhaltige Wismut aufnehmende Schmelzgefäß, die Heizquelle und der Kondensator in einem Vakuumgefäß eingeschlossen sind.To overcome these difficulties in separating bismuth from copper in the To eliminate vacuum, according to the invention, the method is carried out in: a system, in which the melting vessel containing the copper-containing bismuth, the heating source and the condenser are enclosed in a vacuum vessel.

Wohl sind Schmelzvorrichtungen bekannt, bei welchen das Schmelzgefäß und die Heizquelle in einem Vakuumbehälter untergebracht sind. Bei der bekannten Schwierigkeit der Befreiung des Kupfers gerade von Wismut war sicherlich nicht ohne weiteres zu erwarten, daß gerade eine Einrichtung dieser Art eine so weitgehende Beseitigung des Wismuts bewirken würde.Melting devices are well known in which the melting vessel and the heating source are housed in a vacuum container. With the well-known The difficulty in freeing copper from bismuth was certainly not without it It is also to be expected that an institution of this kind would be so far-reaching Elimination of bismuth.

Um die Vakuumpumpe vor der Einwirkung des destillierten Stoffes zu schützen, kann man, falls derselbe sehr weit mitgerissen wird, zwischen den Vakuumbehälter und die Pumpe eine Filtereinrichtung einschalten. Ausführungsbeispiel In einem in ein Vakuumgefäß eingebauten Kohlegriesofen wurde wismuthaltiges Kupfer mit o, o 15 % Wismut unter Aufrechterhaltung eines 95%igen Vakuums auf irloo° C erhitzt und das überdestillierte Wismut in einem in dem gleichen Gefäß angeordneten Kondensator kondensiert; der Wismutgehalt wurde durch diese Behandlung auf unter o,oo i o/o herabgesetzt.In order to protect the vacuum pump from the effects of the distilled substance, a filter device can be inserted between the vacuum container and the pump if the same is carried along very far. Embodiment In a built in a vacuum vessel carbon grains furnace bismuth-containing copper with o, o 1 5% bismuth was heated condensed while maintaining a 95% vacuum to irloo ° C and distilled over bismuth in a cylinder disposed in the same vessel capacitor; the bismuth content was reduced to below o, oo io / o by this treatment.
