Heap leaching - Wikipedia
08-10-2005 · Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of stone 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 …

(Liquid-Solid) Leaching Preparation of Solids for Leaching
(Liquid-Solid) Leaching Leaching is a liquid-solid operation. The two phases are in intimate contact, the solute(s) can diffuse from the solid to the liquid phase, which causes a separation of the components originally in the solid. A special leaching process, when an undesirable component is removed from a solid with water, is called washing.
