  • Gold CIL & CIP Gold Leaching Process Explained CCD

    Developments in The carbon-in-pulp ProcessDesign CriteriaCommercial OperationsIn the carbon-in-pulp process activated carbon is mixed with a ground ore plus water slurry in which gold and silver cyanides are dissolved. After the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped. The barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation. The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill wh

  • Activated Carbon in Gold Cyanidation

    How Activated Carbon WorksThe Gold Cyanidation ProcessCharacteristics of Activated Carbon For Gold RecoveryRegenerating 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, such as in the purification.

  • How Gold Works

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
