Lead Nitrate
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 used in flotation, the manufacture of detonators, pyrotechnics, ceramics, and laboratory applications.
Aerocell is the only manufacturer of lead nitrate in South Africa. Our focus on customer service enables us to supply lead nitrate according to individual needs.
Improve gold yield and lower cyanide consumption
Lead nitrate reduces cyanide consumption through two complementary mechanisms:
- Precipitation of lead sulphide (PbS) on sulphide minerals, forming a sparingly soluble layer that further inhibits cyanide decomposition.
- Formation of lead hydroxide (Pb(OH)2) layer on pyrite, which passivates the surface and suppresses cyanide-consuming side reactions.
Optimise lead nitrate consumption
- Thiocyanate (SCN⁻) levels in solution serve as a reliable indicator of sulphide oxidation.
- Monitoring SCN⁻ enables precise lead nitrate dosing, optimising reagent efficiency and minimizing excess addition.
