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 ...
Microbial leaching is a green gold extraction process with low pollution and energy consumption. It also has promising abilities in dealing with low-grade materials and secondary resources. ... cyanidation is widely welcomed by gold plants because of its low cost of reagents and equipment. In addition, it has a long history and proven ...

The main gold recovery equipment used in the cyanide gold processing plant are as follows: the leaching agitation tank, the high efficiency low consumption rapid desorption electrowinning system, the washing thickener, the zinc powder replacing device, and etc. The leaching agitation tank is applied to the conventional cyanide leaching …
③ Chute for gold extraction. The main equipment for gold selection in the chute is the spiral chutes, which use inclined water flow for separation. By the combined forces of water flow, mineral gravity, and friction between the ore particles and the bottom of the groove, the ore particles settle in the groove according to their specific gravity.

In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. For the carbon-in-pulp method, the ground ore is mixed with water before cyanide is added.
