If the carbon is not strong enough it will be broken in the adsorption process which will cause the loss of gold with the broken carbon. 2.The process is more complicated and contains many process flows. 3.Gold CIP method is not suitable for gold ores with high silver content.

  • What is Gold Cyanidation with picture What is Gold Cyanidation with picture

    The cyanidation process begins after the gold has been discovered and the raw ore separated from the ground often by explosive means. The ore is ground up to better facilitate the leaching process. Breaking up the ore into finer pieces is called heap leaching. Processing the ore immediately without crushing it is known as dump leaching.
