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
