  Verfahren zur elektrolytischen Gewinnung von Kupfer aus seinen Erzen. 
 EMI1.1 
 ohne   Diaphragma ausgeführt,   so entstehen bei Anwendung von konzentrierten   Lusuugeu   und geringen   Stromdichten   lokale Wirkungen. Diese Wirkungen rohren daher, dass das an der Kathode abgeschiedene Kupfer sich in der ammoniakalischen Cuprilöschen wieder lösen 
 EMI1.2 
 



     Diese doppelte Transformation veranlasst   einen kleinen, die Ausbente an reinem Kupfer verringenden Verlust an elektrischer Energie, weicher fast gänzlich vermieden werden kann, wenn das Ammoniak durch Ammoniumkarbonat ersetzt wird. Dies kann in der 
 EMI1.3 
 oder -Sulfit durch Ammonkarbonat ersetzt wird oder dass der Niederschlag von   Kupfer-   oxydulsulfit oder Kupferoxyduloxydsulfit in einer Lösung von Ammoniak oder in einer ammoniakalischen Lösung von Ammoniumsulfat oder -Sulfit aufgelöst und die   Lösung   mit 
 EMI1.4 
 trolyse hat auch den bekannten Vorteil, dass der Elektrolyt in Bewegung versetzt wird.

  Process for the electrolytic extraction of copper from its ores.
 EMI1.1
 If carried out without a diaphragm, local effects arise when using concentrated Lusuugeu and low current densities. These effects stem from the fact that the copper deposited on the cathode dissolves again in the ammoniacal cupril
 EMI1.2
 



     This double transformation causes a small loss of electrical energy, which reduces the yield of pure copper, which can be almost entirely avoided if the ammonia is replaced by ammonium carbonate. This can be done in the
 EMI1.3
 or sulfite is replaced by ammonium carbonate, or that the precipitate of copper oxydulfite or copper oxydulfite is dissolved in a solution of ammonia or in an ammoniacal solution of ammonium sulfate or sulfite and the solution with
 EMI1.4
 Trolyse also has the known advantage that the electrolyte is set in motion.

PATENT-ANSPRUCH : Abänderung des Verfahrens nach Stammpatent Nr. 33799, dadurch gekennzeichnet, dass das Ammoniak der ammoniakalischen Ammoniumsulfat oder -Sulfitlösung durch Ammoniumkarbonat ersetzt wird oder dass der Kupferoxydulsulfit- und Kupferoxyduloxyd- EMI1.6 von Ammoniumsulfat oder-Sulfit gelöst und die Lösung durch Einleiten von Kohlensäure vor oder während der Elektrolyse gesättigt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Modification of the method according to the parent patent No. 33799, characterized in that the ammonia of the ammoniacal ammonium sulfate or sulfite solution is replaced by ammonium carbonate or that the copper oxy sulfite and copper oxy sulfite EMI1.6 dissolved by ammonium sulfate or sulfite and the solution is saturated by introducing carbonic acid before or during the electrolysis. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
