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 ...

History Jerritt Canyon Gold

The processing plant has a capacity of 4,500 metric tonnes per day (tpd). Ore initially goes through three stages - crushing, drying and grinding. The ground ore is then treated in a roaster (one of only three permitted gold processing roaster plants in Nevada) where the sulfide and carbon minerals are oxidized.

Alternative lixiviants to cyanide for leaching gold ores

Oxidative chloride-, sulfide-, and ammonia-leaching processes are generally more applicable for the extraction of gold or platinum group metals as a byproduct from base metal sulfide concentrates. Despite the research interest and pilot plant trials on many of the noncyanide gold lixiviants, the majority are still at the development stage.
