The flotation separation of Pb(Ⅱ) from other metal ions by a system containing sodium nitrate, ammonium thiocyanate, cetyltrimethyl ammonium chloride(CTMAC) and water has been studied. The results showed that in the system consisted of 1.0 g NaNO₃, 0.5 mL NH₄SCN(0.1 mol/L) and 1.0 mL CTMAC(0.01 mol/L) at pH=6.0, Pb²⁺ could be floated and separated from the Zn²⁺, Cu²⁺, Cd²⁺, Mn²⁺, Fe²⁺, Co²⁺, Ni²⁺ and Al³⁺ mixture in solution.
