How is lead nitrate used in mining

  • Effect of lead nitrate on cyanidation of gold ores

    Oct 01, 2000· The effect of lead nitrate is subtler for chalcopyrite and pyrrhotite because it was less effective to retard the reaction of sulphides with cyanide and the reaction of iron with oxygen. For gold, the addition of lead nitrate has the same effect with pyrrhotite than with pyrite; inhibiting partially the formation of a sulphur layer.

  • Effect of Lead Nitrate on Gold Leach Kinetics

    Lead nitrate is added to passivate sulphide mineral surfaces, particularly pyrite, so the addition rate should be related to the sulphide mineral content (ignoring pyrrhotite - which requires pre-aeration to diminish the oxygen demand) and specifically the slurry oxygen demand (OD).
