In a mineral processing application, ADR Plant (Adsorption – Desorption – Regeneration) in general follows the CIL/ CIP or Heap Leach Processes. ADR, covers the adsorption of precious metals on active carbon, stripping the carbon with strong cyanide solution, recovery of the metals through the electrowinning, pouring the precious metals as nuggets from the melting pot as well as regenerating the carbon to activate and reuse.
