The result is high cyanide consumption, poor gold dor233 purity and high concentrations of copper-cyanide complexes in tailings that require costly destruction.
Recovering gold from cyanide solution is a very old method, and, it is still employed in large scale recovery of gold from its ores.
Recovery and kinetics of gold and iron from cyanide.
For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant.
May 14, 2013018332The cyanide leaches the gold out, but the cyanide can seep into the ground, causing environmental problems and posing threats to human health.
In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process.
