Description

Reinigung von Zementkupfer. Das handelsübliche Zementkupfer enthält stets mehrere Prozente Chlor neben Blei und Eisen. Bei Verhüttung solchen Zementkupfers gehen, entsprechend den vorhandenen Chlormengen, bedeutende Mengen Kupfer durch Verflüchtigung als Kupferchlorür verloren. Dabei wirken die entstandenen Kupfer- und Bleichloriddämpfe äußerst nachteilig auf die Gesundheit der Arbeiter.Cleaning of cement copper. The commercial cement copper contains always several percent chlorine in addition to lead and iron. When smelting such cement copper Depending on the amount of chlorine present, significant amounts of copper go through Lost volatilization as copper chloride. The resulting copper and lead chloride fumes extremely detrimental to worker health.

Nach dem vorliegenden Verfahren werden die erwähnten Nachteile ganz beseitigt. Demzufolge wird das chlorhaltige Zementkupfer in einem Rührbottich mit Eisenblechabfällen und mit einer etwas größeren Menge Salzsäure, als zur Lösung der basisch:n Chlorverbindungen notwendig ist, behandelt. Es wird dann unter Umrühren eine Zeitlang ererwärmt und dann, um ein rasches, und gänzliches Ausfällen des Zementkupfers zu ermöglichen, auf das Zwei- bis Dreifache mit heißem Wasser verdünnt.According to the present method, the disadvantages mentioned become obsolete eliminated. As a result, the chlorine-containing cement copper is in a stirring vat Iron sheet waste and with a slightly larger amount of hydrochloric acid than for the solution the basic: n chlorine compounds is necessary, treated. It is then stirring warmed up for a while, and then, for rapid and complete precipitation of the cement-copper to allow, diluted two to three times with hot water.

Nach beendigter Zementation wird das Zementkupfer mit Wasser ausgewaschen und bildet dann ein reines., hochprozentiges Material für die Verhüttung. Bemerkt wird, daß die Fällung von sauren Kupferlösungen mit Eisen und auch das, Lösen von basischen Chlorverbindungen des Kupfers durch Salzsäure bekannt ist.When the cementation is complete, the cement copper is washed out with water and then forms a pure, high-percentage material for smelting. Noticed that the precipitation of acidic copper solutions with iron and also the dissolving of basic chlorine compounds of copper is known from hydrochloric acid.
