Extract the gold from the container by pouring off the acid using a filter, then rinsing and refiltering the substance three times with distilled water. The result will be nearly 100 percent gold.

Extraction of gold using cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

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.
