Activated Carbon for Gold Recovery - Puragen
Gold Recovery Process. For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.
