Activated Carbon in Gold Cyanidation
How Activated Carbon WorksThe Gold Cyanidation ProcessCharacteristics of Activated Carbon For Gold RecoveryReactivating Activated CarbonConclusionActivated carbon, a material produced from carbon-rich sources, offers an incredibly porous surface structure, which creates a vast surface area (about an acre per ¼ teaspoon) on which to adsorb materials. This porous structure, in combination with attraction forces, allows activated carbon to capture material components and hold on to them for later recovery. This diverse material is used throughout a number of industries to pull contaminants from liquids or gases, s
