Tank leaching - Wikipedia

Aside from chemical requirements several key factors influence extraction efficiency: • Retention time - refers to the time spent in the leaching system by the solids. This is calculated as the total volumetric capacity of the leach tank/s divided by the volumetric throughput of the solid/liquid slurry. Retention time is commonly measured in hours for precious metals recovery. A sequence of leach tanks is referred to as a leach "train", and retention time is measured considering the total volume of the leac…

Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly ...
