Extraction of Gold Element Gold, Au, Transition Metal

Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanideprocess The extraction of gold by the cyanidemethod is of great technical importance.
