    2021-8-25  Gold Recovery. Gold recovery takes place in mines across the world. Like most other industries, gold extraction must strike the delicate balance between controlling operating costs and maximising the return on investment (whilst maintaining environmental responsibility too). Choosing the right activated carbon supplier is vital to this.

  • Activated Carbon for Gold Recovery Puragen Activated

    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.
