Dec 12, 2019· Heap leaching is one of the oldest and the most traditional mining process used to extractvaluable metalsfrom specific minerals. This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally, heap leaching was practised 500 years ago.

Gold Mine Heap Leaching Process.Crushedbyjaw crushersand cone crushers to a certain particle size (30-50mm),raw oreis directly sent for heaping or granulated (to make finer particles agglomerate into coarse powder), and then transported to the ore heap site for heap construction. On the laid ore heap site, the heap system is set up.
