extraction and recovery equipment gold copper and silver. 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.
