To achieve efficient flotation of azurite, the influence of a new sulfurizing agent, GX2, on the sulfide flotation behavior of azurite was investigated through single-mineral flotation tests, with comparisons made to sulfurizing agents such as ammonium sulfate and sodium sulfide. Testing methods including Zeta potential measurement, contact angle tests, adsorption capacity tests, and X-ray photoelectron spectroscopy analysis were employed to explore the sulfidation mechanisms of different agents on azurite. The results indicate that GX2 exhibits superior sulfidation performance compared to the other two agents. Under conditions of pulp pH of 9, sulfidation time of 2 min, dibutyl dithiophosphate dosage of 120 mg/L, GX2 dosage of 20 mg/L, and collector oil dosage of 80 mg/L, the maximum flotation recovery rate of azurite can reach 94.37%. GX2 acts on the surface of azurite through chemical adsorption, enhancing its electronegativity and forming hydrophobic Cu—S components on the mineral surface, thereby increasing the adsorption capacity of collectors and improving the sulfidation effect on the mineral surface.

为实现蓝铜矿的高效分选,通过单矿物浮选试验,研究了新型硫化剂GX2对云南某蓝铜矿硫化浮选行为的影响,并与硫酸铵、硫化钠等传统硫化剂进行了对比。采用Zeta电位测定、接触角测试、吸附量测试和X射线光电子能谱分析等测试方法,探讨了不同硫化剂对蓝铜矿的硫化作用机理。结果表明,GX2对蓝铜矿的硫化效果优于其他两种硫化剂;在矿浆pH=9、硫化时间为2 min、丁基黄药用量为120 mg/L、GX2用量为20 mg/L、2#油用量为80 mg/L的条件下,蓝铜矿的最大浮选回收率可达到94.37%;GX2以化学吸附的形式作用于蓝铜矿表面,使其电负性增强,并在矿物表面生成了疏水性Cu—S组分,增加了矿物表面捕收剂的吸附量,从而改善矿物表面的硫化效果。

为实现蓝铜矿的高效分选,通过单矿物浮选试验,研究了新型硫化剂GX2对云南某蓝铜矿硫化浮选行为的影响,并与硫酸铵、硫化钠等传统硫化剂进行了对比。采用Zeta电位测定、接触角测试、吸附量测试和X射线光电子能谱分析等测试方法,探讨了不同硫化剂对蓝铜矿的硫化作用机理。结果表明,GX2对蓝铜矿的硫化效果优于其他两种硫化剂;在矿浆pH=9、硫化时间为2 min、丁基黄药用量为120 mg/L、GX2用量为20 mg/L、2#油用量为80 mg/L的条件下,蓝铜矿的最大浮选回收率可达到94.37%;GX2以化学吸附的形式作用于蓝铜矿表面,使其电负性增强,并在矿物表面生成了疏水性Cu—S组分,增加了矿物表面捕收剂的吸附量,从而改善矿物表面的硫化效果。

To achieve efficient flotation of azurite, the influence of a new sulfurizing agent, GX2, on the sulfide flotation behavior of azurite was investigated through single-mineral flotation tests, with comparisons made to sulfurizing agents such as ammonium sulfate and sodium sulfide. Testing methods including Zeta potential measurement, contact angle tests, adsorption capacity tests, and X-ray photoelectron spectroscopy analysis were employed to explore the sulfidation mechanisms of different agents on azurite. The results indicate that GX2 exhibits superior sulfidation performance compared to the other two agents. Under conditions of pulp pH of 9, sulfidation time of 2 min, dibutyl dithiophosphate dosage of 120 mg/L, GX2 dosage of 20 mg/L, and collector oil dosage of 80 mg/L, the maximum flotation recovery rate of azurite can reach 94.37%. GX2 acts on the surface of azurite through chemical adsorption, enhancing its electronegativity and forming hydrophobic Cu—S components on the mineral surface, thereby increasing the adsorption capacity of collectors and improving the sulfidation effect on the mineral surface.
