Learn About the Heap Leaching Process & Mining Techniques

10/01/2019· 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.

Learn About the Heap Leaching Process & Mining Techniques

In heap leach mining the ore is prepared according to its starting particle size, and is typically crushed to achieve a particle size within the desired range of about 5mm. This particle size is desirable since it makes it easier for the leach solution to percolate through the ore, as well as achieve ideal particle size distribution for
