  Factors Affecting Gold Leaching Effects: A …

  201811 · For instance, when gold was split and dispersed equally within the pyrite layer and within the adjacent quartz layer, gold dissolution was found to be around 35%, suggesting a negative effect of released species from pyrite. Cyclic voltammetry and potentiodynamic polarization findings are in line with the cyanide leaching results.

  Pretreatment Process on Refractory Gold Ores with As

  It can dramatically improve gold cyanide leaching rate. Roasting has advantages of mature and reliable technology, simple operation, adaptability, etc. But it is easy to form sec-ondary wrapping to reduce leaching rate of gold in the roast-ing process, and at the same time produces gases of SO2 and As2O3 polluting environment seriously. In ores with a high …
