Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Effect of pH on Cyanidation Process - Hydrometallurgy ...

Running your CIL at a lower pH the causes the reaction to be more thorough rather than faster at lower pH conditions. What this means is- The lower pH may increase the number of free CN- ions and therefore as the concentration of dissolved CN ions is the main driver of dissolution rate of gold then the lower pH stands to drive the reaction faster or more thoroughly.
