    Elution behaviour of metals from carbon

    saimm/Conferences/Hydro2009/475 484_Jeffrey.pdf

    ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon in pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

    Gold CIL & CIP Gold Leaching Process Explained CCD

    911metallurgist/blog/gold cil process explained

    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.

    Elution and Carbon Cool. During the elution cycle, water is drawn from the potable water tank and pumped through the heat exchanger via valve AV 409 into the column. The water then flows up through the column, taking with it gold that has been freed into solution during the preheat stage.

    ELUTION & CARBON REACTIVATION 9999 Elution Circuit Components Elution Column The elution column is a 10m high by 1.2m diameter mild steel rubber lined pressure vessel (rated to 350kPa). Having a high length to diameter ratio enables solution to flow evenly through the bed of carbon without short circuiting or tunnelling.

    elution profile of cyanide is known in order to simulate the profile of gold elution (4). A number of papers have appeared on the mechanism and kinetics of the decomposition of cyanide in the presence of activated carbon (9 14). Under industrial alkaline condition of gold elution, cyanide is decomposed

    sciencedirect/science/article/pii/S0892687502003151·

    The feasibility of using ultrasound to enhance the elution of gold from activated carbon was investigated. A laboratory scale elution column immersed in an ultrasonic bath was used to investigate three eluant systems. The kinetic activity of the activated carbon was improved in the elution with sonication.

    It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly. The presence of spectator cations (M n+) enhances the formation of M n+ {Au(CN) 2 } n ion pairs on the carbon, which in turn suppress the elution of gold cyanide. The ...
