    Effect of lead nitrate on cyanidation of gold ores 1267 It is interesting to note that when the gold electrode treated with lead sulfide was put in 1 M NaCN solution without lead nitrate addition, and the same potential sweep used in Figure 3 was performed, four peaks were obtained as shown in Figure 4.

    These extractions, however, were considerably lower than those of the control tests where orpiment and stibnite were absent. Tests were run in which the effects of lead nitrate at pH 10 were investigated on the cyanidation of synthetic gold ores containing these minerals. The usual procedure was followed.

  • Effects of sulfide and lead nitrate addition to a gold

    The addition of lead nitrate to sulfides in cyanide solution can create a synergetic effect which results in an increase in dissolution rates of gold in cyanide solutions and this is accompanied by a drop in the corrosion potential of gold and a dramatic decline in thiocyanate and free sulfide concentrations.

    Effect of lead nitrate on cyanidation of gold ores: This layer is less important in presence of lead. 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.

    Effect of lead nitrate on cyanidation of gold ores . The effect of lead nitrate addition on the cyanidation of gold ores has been studied (Sayiner, 2014) and it is believed that the catalytic activity of lead on anodic dissolution of gold consists on the formation of gold lead alloys such as AuPb2, AuPb3 and metallic lead on the surface of gold.
