Gold never reacts with oxygen (one of the most active elements) which means it will not rust or tarnish Yet this is precisely what Russian commercial precious metal trading company International Reserve Payment System discovered on thousands of (allegedly) 999 gold coins St George issued by the Central Russian Bank
For this reason alone copper leaching in aerated solutions under oxygen limiting conditions is faster than gold leaching in identical solutions The presence of copper(I) had no impact on the gold or copper leach rate until at copper(I) additions 10 mmol/L where the free cyanide concentration became depleted (cyanide copper mole ratio 3 1)
