leaching in gold mineral processing and gold extraction new

Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a

    The industrial gold heap leaching process can be divided into two types, one is short-term gold heap leaching and the other is long-term gold heap leaching. In the short-term gold heap leaching process, the ore is usually crushed to less than 20 mm. When processing gold-bearing quartz veins, it is often crushed to less than 6 mm
