    The gold bearing liquid is then separated from the leached solids in thickener tanks or vacuum filters, and the tailings are washed to remove gold and cyanide prior to disposal. The separation and washing take place in a series of units by a process referred to as counter current decantation (CCD). Gold is then

  • Valves for gold production with CIL, CIP or CIC circuits ...

    In the CIL circuit, cyanide and oxygen are added to the slurry, resulting in gold being dissolved from the ore. Activated carbon is then fed into the process from the opposite direction, against the slurry stream, and as it moves through the CIL tanks, dissolved gold adsorbs onto the activated carbon.

    pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. This represents a gold recovery of 90–99% depending on the tenor of the feed solution.

  • Gold CIL & CIP Gold Leaching Process Explained CCD

    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-in-pulp process.

    Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

    circuit. In a CIL plant, the carbon granules are added directly into the gold leaching tanks, so that leaching of gold (from the ore phase to the leachate), and adsorption of gold (from the leachate to the carbon), occur simultaneously. In a CIP plant, a series of small adsorption tanks is installed after the leach plant


    the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2.
