The second occurs when graphite or carbonaceous matter is present. In this case the gold leaches well into the cyanide solution but then the carbonaceous minerals reabsorb the gold back into the pulp. This is known as “preg-robbing”. SGS experts will identify the best solution for your ore as there are many methods to choose from:

Activated Carbon for Gold Recovery Puragen Activated Carbons

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.
