What is Lead Nitrate Influence on pH Hydrometallurgy

That lead nitrate works on pyrite by decreasing cyanide consumption. The difference in the nature of the results may be related to the amount of pyrite, the length of the pre-leaching, and the amount of lead nitrate added. The gold content in the leach residue was higher by about 0.15 grt in absence of lead nitrate.
