effect of lead nitrate on gold leaching

  • Effect of oxygen and lead nitrate on the cyanidation of a

    the combination of lead nitrate and oxygen are useful in reducing cyanide consumption but the reduction of gold recovery is attributed to the fact that the gold leaching rate is function of the ratio of cyanide and lead nitrate and the pH and the actual ratio is not optimized.
