INFLUENCE OF LEAD NITRATE ON CYANIDE LEACHING

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).
