This paper deals with the effect of the addition of lead nitrate and ultra-fine grinding on the cyanidation of an antimonial refractory gold and silver ore. The results indicated that the recovery of gold was enhanced by 10%, but, silver extraction
Various leaching parameters such as particle size, cyanide concentration, pH and the application of oxygen and lead nitrate have been investigated for the recovery of gold from an ore containing pyrite and small amounts of pyrrhotite and chalcopyrite.

The use of lead nitrate has become widespread in gold cyanidation to improve leaching kinetics and increase gold recovery since the 1990s. Lead nitrate is also widely used in flotation of rare earth metals, manufacture of detonators, pyrotechnics and in laboratory applications.
