GOLD AND SILVER - Records Collections

2021-9-5  High value ores are treated by agitation leaching, shown in Exhibit 4, to maximize the recovery of metal values. The ore is crushed and ground in water to form a slurry. Cyanide is usually added at the grinding mill to begin theleaching process and more cyanide may be added to the leaching tanks. Ores may be leached anywhere from 24 to 72 ormore hours. Silver ores tend to require longer leaching times. The method of recovering the precious metal fromsolution determines how the solution is separated from the solids. If the Merrill-Crowe or carbon-in-column metalrecovery process is used, the leach liquor will be washed out of the solids, usually by a combination of counter-currentdecantation and filtration washing with water. This produces a concentrated wash solution and recovers the maximumpregnant liquor from the solids. The resultant slurry will contain very little cyanide or gold and would not be expected toany exhibit hazardous characteristics. If carbon-in-leach or carbon-in-pulp metal
