EMI2.1
Nach der Elektrolyse wird die Lösung, die ein Gemisch aus Ammoniumsulfat und-sulfit enthält, zur Auflösung einer neuen Menge von Kupferoxyduloxydsulfit benutzt. Da diese Lösung sich mit Ammoniumsulfat immer mehr anreichert, wird ein Teil davon von Zeit zu Zeit entnommen und behufs Wiedergewinnung des Ammoniaks, das zur Auflösung des Kupferoxydul- oxydsulfits erforderlich ist, in der oben angegebenen Weise behandelt.
Zur Wiedergewinnung des Ammoniaks kann man ganz allgemein eine erdalkalische Base verwenden ; es wird aber dem Kalk wegen seines geringen Preises der Vorzug gegeben. Im übrigen können in vielen Fällen auch diese geringen Kosten fortfallen, denn die meisten Kupfererze enthalten eine geringe Menge Kalk, Magnesium-oder Baryumoxyd, meistens in der Form von Karbonaten, so dass das Erz selbst an Stelle von Kalk verwendet werden kann, um das Ammoniakgas wieder zu gewinnen.
Die durch Elektrolyse erschöpfte Lösung kann zur Gewinnung von schwefliger Säure verwendet werden, indem man vor der Behandlung mit Kalk diese Lösung mit der nach der Sulfitierung zurückbleibenden Lösung, die ein Molekül Schwefelsäure enthält,

EMI2.1
After the electrolysis, the solution, which contains a mixture of ammonium sulphate and sulphite, is used to dissolve a new amount of copper oxy-sulfite. As this solution becomes more and more enriched with ammonium sulphate, part of it is withdrawn from time to time and treated in the manner indicated above for the purpose of recovering the ammonia which is necessary to dissolve the copper oxy-sulfite.
In general, an alkaline earth base can be used to recover the ammonia; but lime is preferred because of its low price. In addition, these low costs can be omitted in many cases, because most copper ores contain a small amount of lime, magnesium or barium oxide, mostly in the form of carbonates, so that the ore itself can be used instead of lime to produce the ammonia gas to win again.
The solution exhausted by electrolysis can be used to obtain sulphurous acid by mixing this solution with the solution remaining after sulphitation, which contains one molecule of sulfuric acid, before treatment with lime.
EMI2.2
When this solution is mixed and boiled with the solution resulting from the suinting, the following reaction occurs:
