One method involves dissolving the gold with a concentrated cyanide solution, allowing the resulting liquid to run away from the remaining ore and collecting it for reconstitution. The concentrations of cyanide used in this process are extremely dangerous, and if spilled into the environment, pose a significant threat to wildlife and human health.
