      2.1 Leaching. Most copper leaching is done by piling broken ore (0.5% Cu) into flat surface, 310m high, 10 4 10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 15kg Cum 3.

      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.
