Learn About the Heap Leaching Process & Mining

2019-1-10  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.

Currently, approx. 20% of world production of mined copper and gold is realized using heap leaching techniques. A special heap leaching technique (bio-heapleaching) is used on certain types of sulphidic copper ores where insoluble copper, nickel, zinc, cobalt sulphides and uranium oxides are converted into water soluble sulphates in a two-step leaching process with the help of natural iron oxidising 11
