Lead Nitrate (Gold/Silver Activator)
CAS Number: 10099-74-8
Lead Nitrate is an activator used in gold, silver, and antimony sulfide flotation circuits to enhance the collection of native gold, electrum, arsenopyrite, and tetrahedrite. Lead ions adsorb on the mineral surface, improving collector adsorption and increasing hydrophobicity. It is particularly effective in circuits processing refractory gold ores where conventional xanthate collectors underperform, and is also used to activate depressed sulfide minerals in sequential flotation schemes.
