  • Gold Carbon In Leach Plant Updated January, 2017

    A flowsheet, showing the Carbon In Leach (CIL) process This circuit utilizes a thickener, to maintain a constant percent solids in the ore feed, necessitating less water used in the process, smaller tanks and a smaller pond. It also gives much more control over the process that a conventional CIL plant without a thickener.

  • How is cyanide used in gold mining? Quora

    Cyanide has been the leach reagent of choice in gold mining because of its high gold recoveries, robustness and relatively low cost. As a result, over 76% of all gold extracted worldwide is produced by hydrometallurgical extraction with the use of cyanide. The gold mining sector uses approximately 66,000 tons of sodium cyanide annually worldwide.
