  • Gold Cyanidation Heap Leaching

    Oct 12, 2019Heap 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.
