Description

Verfahren zum Raffinieren von Kupfer Bekanntlich geschieht das Raffinieren von Kupfer in der @\'eise, daß Rohgut in einem feststehenden oder drehbaren Herdofen niedergeschmolzen. alsdann durch Ein- oder Aufblasen von Luft oxydiert und nach Entfernung der hierbei entstandenen Schlacke reduziert (gepolt) wird.Process for Refining Copper As is well known, refining occurs of copper in the iron, that raw material in a fixed or rotating hearth furnace melted down. then oxidized by blowing air in or out, and afterwards Removal of the resulting slag is reduced (polarized).

Der Oxvdationsprozeß verlangt dabei naturgemäß eine möglichst große Badoberfläche, während beim Polprozeß die kleinstmögliche Badoberfläche die günstigste ist, weil das zu polende und besonders das bereits gepolte Kupfer peinlichst vor der Aufnahme von Sauerstoff aus der Luft geschützt werden muß.The oxidation process naturally requires as large a process as possible Bath surface, while in the pole process the smallest possible bath surface is the cheapest is because the copper to be polarized and especially the copper that has already been polarized is meticulously prepared the absorption of oxygen from the air must be protected.

Aus diesem Grunde werden die beiden Verfahrensstufen in verschiedenen Ofen, und zwar wegen der schnellen Umfüllmöglichkeit in kippbaren Drehflammöfen durchgeführt. Der Herdraum des Oxydationsofens erhält dabei einen flachen Herd, dessen Badtiefe etwa '/. der Badlänge beträgt, während beim Polofen die Badtiefe etwa gleich der Badlänge ist, so daß nur eine ganz geringe Oberfläche des Bades im Verhältnis zur Kupfermenge der Luft ausgesetzt ist.For this reason, the two process stages are in different Oven, because of the quick transfer possibility in tiltable rotary flame furnaces carried out. The oven space of the oxidation oven is given a flat hearth, whose bath depth is about '/. the bath length, while the bath depth in the polo oven is approximately equal to the bath length, so that only a very small surface area of the bath exposed to air in relation to the amount of copper.

Die neue und eigenartige Form des Polofens begünstigt im besonderen Maße das an sich bekannte Polen mit Gasen oder Kohlenstaub, da die Düsen in bekannter Weise durch den Ofenmantel geführt werden können. Letzterer Umstand wird volkswirtschaftlich besonders bedeutungsvoll werden, wenn der Verwendung der üblichen Polbäume in der Zukunft wegen des immer kleiner werdenden Bestandes eine Grenze gesetzt sein wird. Nach dem Erfindungsgedanken werden außerdem die Düsen so eingerichtet, daß sie neben der Einführung der Polmittel auch zum Beheizen mit 01 oder Gas und radial gerichteter Flamme dienen können.The new and peculiar shape of the polo furnace particularly favors the well-known poling with gases or coal dust, since the nozzles can be guided through the furnace shell in a known manner. The latter circumstance will become particularly important economically when the use of the usual pole trees is set a limit in the future because of the ever smaller population. According to the inventive idea, moreover, the nozzles are arranged so that they can also serve for heating or gas with 01 and radially directed flame in addition to the introduction of the pole means.
