  • Effect of lead nitrate on cyanidation of gold ores

    01.10.2000· For the case of the cyanidation done in the presence of pyrite, there is more sulphur on the gold foils with no lead pre-leaching than with pre-leaching (Figure I0). The lead nitrate pre-leaching reduces the dissolution of the sulphur from the pyrite. Some sulphur, instead of forming thiocyanate, is adsorbed on metallic gold.
