    Effect of Lead Nitrate on pH (8 replies) It was found that lead nitrate is detrimental to the process when not added properly It can inhibit the kinetics of dissolution of gold and increase the cyanide consumption. Research on the electrochemical aspects of lead nitrate suggests that its addition increases the dissolution kinetics of gold, even in the absence of sulphides.
