ammonium hydroxide, and by controlling the pH with Ca(OH) 2. Best extractions were achieved with liquid-solid ratio of 10:1, which provided an extraction of 86 % gold, 90.1 % silver, and 88.4 % copper. NH 4 OH was used for complexation of copper and controlling the pH above 10. Consumption of (NH 4) 2 S 2 O 3 was 20 g/L, which makes it technically feasible for industrial scale process option ...

Copper-Ammonia Complex | Chemdemos

When concentrated ammonia solution (ammonium hydroxide) is added to a clear, light blue, aqueous solution of copper(II) chloride, a powdery, light blue precipitate of copper(II) hydroxide forms. Further addition of ammonia causes the copper ion to go back into solution as a deep blue ammonia complex. The addition of 12M sulfuric acid reverses the changes through the copper hydroxide precipate ...

Eliminating Copper from Gold Ore

11/10/2015· The copper and ammonia are recovered from the preliminary leach solution by distillation, the copper remaining as an oxide precipitate. The success of this process will depend largely upon the relatively complete solubility in ammonia of those copper minerals which dissolve in cyanide. Chemical reaction of copper minerals and cyanide. The Hunt method-calls for the direct treatment of the ore ...
