  • 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

  • Leaching (metallurgy) Wikipedia

    Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts. These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially much less harmful

    Then if needed, column test feeds are agglomerated to improve the permeability and strength of the stacked feed. A leach solution is then applied to the top of the column, at a constant flow rate. As the solution percolates through the column it dissolves and concentrates constituents into a pregnant leach solution (PLS). The PLS is collected
