  • The Geochemistry of the Leached Capping of the La Granja

    01/01/1981· Ninety rock samples from the La Granja porphyry copper in northern Peru have been analyzed for 30 elements, 10 of which are discussed here. Although intense weathering has produced a leached capping up to 200 m thick, the distribution of Mg, Ca, Na, K, Rb and Sr can still be correlated with different phases of hydrothermal alteration. There has been complete supergene leaching of

  • The selective leaching of copper from a gold–copper

    Copper selective leaching will reduce the gold losses due to a cementa-tion mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the pre-leaching stage. Nguyen et al. (1997a, 1997b) found that, at ambient conditions and pH 11, all gold in a solution containing 1000 mg/L NaCN and 0.5 g/L Cu had been cemented on copper in the first 2 h. According

  • Gold & Copper Bioleaching

    Bacterial Leaching of Copper Ores Several types of bacteria capable of living in an acid environment have been isolated from copper mine waters. The foremost of these are of the genus Thiobacillus (T.). Thiobacillus bacteria are acidophilic aerobic chemolithotrophs which grow most rapidly at a pH in the range of 2-3. T. ferrooxidans derive their energy by oxidizing ferrous iron, elemental
