  • Gold Extraction an overview | ScienceDirect Topics

    The effect of pH value on gold extraction for various ore types is shown in Figure 284 Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 95–100, whereas for some carbonaceous ores, pH value has no apparent effect However, the outcome will vary depending on theFirst off, as hydrogen peroxide is a very strong oxidizer and thus used to destroy cyanide, I doubt if you really want to add it to your CIL circuit By the same reasoning you probably do not want to add it to any part of your water circuit where it can get back to your leach circuit You probably want to add it to your tails just before disposalHydrogen Peroxide in CIL Gold Leaching Circuit

  • Leaching and adsorption circuits – for better metal extraction

    The LeachCIP circuit is a system comprised of separate leaching and adsorption tanks In leaching, ore which has been ground to pulp is placed in agitated tanks with sodium cyanide solution and gold and silver is dissolved into the slurry solution The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached2015年11月1日· The screens only allow smaller ore particles to pass through Fresh carbon from the elution circuit enters the last CIL tank Countercurrent transfer of carbon particles takes place using slurry pumps at regular intervals The carbon in the first tank has highest gold loading and is sent to the elution circuit for gold removalModeling and optimization of Carbon in leach (CIL) circuit for gold
