conventional heap leaching. The process involves the coating of concentrates onto a suitable substrate, usually barren rock, then stacking the coated material in a conventional heap fashion. The heap is irrigated with acidic solutions containing iron and nutrients while low pressure ambient air is applied at the heap

Heap leaching

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 reseparate 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

Improvements in Copper heap leaching by use of wetting

A sprinkler system is installed on top of each heap allowing the diluted sulfuric acid to be fed uniformly over the ore. While the solution percolates through the heap, copper is leached out of the ore. The pregnant leaching solution is collected by a drainage system below the heap and is led through a collection ditch into a pond.

Gold Cyanidation Heap Leaching cnlitereagent

Heap leaching is a method in which a leaching solution is sprayed with a spray leaching system to selectively leach the useful minerals in the ore and recover the useful mineral from the pregnant liquid flowing out of the heap during the infiltration process. Lowgrade gold ore heap leaching is a new gold extraction process developed in the 1980s.
