HEAP LEACHING TECHNIQUE in MINING - Euromines

Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching, which has a relatively low level of energy consumption, is for example 1MB

Heap leaching - Wikipedia

OverviewProcessEnvironmental ConcernsSee alsoExternal linksHeap 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 ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i…Wikipedia · CC-BY-SA 许可下的文字

Learn About the Heap Leaching Process & Mining Techniques

Jan 10, 2019· Heap leach mining is an industrial hydrometallurgical process, where the metal contained in an ore body is extracted by dissolution. The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a “pregnant” solution which, is then captured and later recovered downstream in the processing line.
