heap leaching - an overview sciencedirect topics most copper leaching is done by piling broken ore 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.
Advantages of heap leaching with ore concentration high capacity
advances in high-temperature heap leaching of refractory ... the application of bacterial heap leaching to refractory chalcopyrite ores introduces further complexity, such as the need to improve leach kinetics by raising the heap temperature. high leach temperatures are required to achieve meaningful chalcopyrite leach rates and extractions, which may be attained by the bacterial oxidation of
= 10 mm; acid concentration of spray solution of 75 g/l, spraying flow rate of acid solution 30 l/m 2 h; acid consumption 40 kg/t of ore. the leaching efficiency reaches gt;80%. 3.5.
heap leaching with ore concentration high capacity application
