  • Gold Extraction an overview ScienceDirect Topics

    The effect of pH value on gold extraction for various ore types is shown in Figure 28.4.Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect. However, the outcome will vary depending on the nature of the gold and background mineral matrix.
