  • Gold CIL & CIP Gold Leaching Process Explained CCD

    The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon

  • Leaching & Adsorption Resource Book

    Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated

  • Carbon-in-Pulp CIP Gold Adsorption from Cyanide Leach

    Slurry was pumped from an elevated feed tank by a Cole-Parmer pump that also metered the feed to the first adsorption tank. Carbon was moved from the slurries with a small, 28-mesh-screen dipper. Samples were lightly washed with water and measured in a small pharmaceutical graduated cylinder, submerged in water, using a bulk-weight-to-volume ratio of 0.45 g/ml.

  • Adsorption Tank goldcilplant

    Adsorption Tank. Adsorption tank is very similar with leaching tank, except that adsorption tank has carbon segregation screen and air lifter, which contribute to adsorb the gold to the activated carbon. Driven Mode: Mechanical agitation type; Combined agitation type. Model: Φ2.0*2.5m~ Φ9.5*10.0m

  • The process design of gold leaching and carbon-in-pulp

    minimize screen blocking in the adsorption section. After feed pre-screening the pulp flows through a cascade of well-mixed adsorption tanks, typically 6 to 8 in number. Conventional practice is to have a mean pulp residence time of about an hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10–25 grams of carbon per litre

    B. Leaching and adsorption: The slurry will enter into 8 sets of double impeller leaching tank; well-mixed sodium cyanide agents are added to the first tank; active carbon is added to the tanks from the second to the eighth; active carbon from the second agitator is lifted to carbon screen to get gold-loaded carbon, and after cleaning, the gold

  • Ore processing Waihi Gold

    The slurry then moves through a series of carbon adsorption tanks (3). While the leaching process continues in these tanks, the primary objective is to remove the gold and silver from the solution. To achieve this, carbon is fed through the tanks (4) and the gold and silver adsorbs (attaches) to the carbon granules. Carbon is heated to 600 degrees C and fed into the circuit in the opposite

    Regarding leaching kinetics, metallic silver has been found to dissolve faster than gold (Hiskey and Sanchez, 1990, Senanayake, 2006, Lin et al., 2010).Several authors have reported that the presence of silver, alloyed with gold, has a beneficial effect on gold leaching kinetics (Jeffrey and Ritchie, 2000, Xue and Osseo-Asare, 2001, Dai and Jeffrey, 2006, Senanayake, 2006, Senanayake, 2008

  • Carbon Adsorption In Recovery Of Gold Mine

    Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions . It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970's, with the explosion of heap leaching of
