use of lead nitrate in gold leaching - arso-sculpture.fr

cyanide leaching by addition of 300 g/Mg lead nitrate to the leach slurry. Furthermore, numerous studies have shown that lead nitrate addition reduces the detrimental effect of metallic sulfides, increases gold leaching recovery and/or inhibits the dissolution of metallic sulfides, thus reduces cyanide consumption (Deschenes et al., 2003).

Effect of lead nitrate on cyanidation of gold ores ...

In a cyanide solution, lead nitrate, lead sulphide and lead sulphite react with gold to form AuPb 2, AuPb 3 and metallic lead, which clearly accelerate the gold dissolution. The nature of the sulphide minerals affects the formation of lead or lead alloys on the gold surface. XPS did not find any lead on the surface of gold in the presence of pyrite or pyrrhotite but found a very thin layer ...

Effect of lead nitrate on cyanidation of gold ores ...

01/10/2000· The lead nitrate pre-leaching reduces the dissolution of the sulphur from the pyrite. Some sulphur, instead of forming thiocyanate, is adsorbed on metallic gold. Therefore the less sulphide dissolution, the less sulphur adsorption occurs on gold. A similar phenomenon is seen in the case of the cyanidation in the presence of pyrrhotite (Figure 11). However, this is not observed for the case of ...
