Heap Leaching an overview ScienceDirect Topics

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m 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 1–5kg Cum −3.

Bioleaching: metal solubilization by microorganisms

1997-7-1  To keep enough iron in solution the chemical oxidation of metal sulfides must occur in an acid environment below pH 5.0. The ferrous iron arising in this reaction can be reoxidized to ferric iron by T. ferrooxidans or L. ferrooxidans and as such can take part in the oxidation process again. In indirect leaching the bacteria do not need to be in contact with the mineral surface.
