| 摘 要： | 为确定黄药在孔雀石表面的吸附形式，用剩余浓度法研究了孔雀石表面丁基黄药的吸附和解吸特性。结果表明，孔雀石表面吸附丁基黄药达到饱和所需的搅拌时间为3 min，解吸达到平衡需要的时间为4 min；硫化钠的用量为100 g/t、pH为9、50℃时丁基黄药在孔雀石表面的吸附效果最佳。红外光谱分析表明，黄药在孔雀石表面吸附后生成了黄原酸铜等疏水物质，其吸附形式主要是化学吸附中的离子交换吸附。

| Abstract: | To determine the adsorption form of xanthate on malachite surface，the residual concentration method was employed to study the adsorption and desorption properties of butyl xanthate on malachite surface.Results show that，butyl xanthate adsorption on the surface of malachite reach saturation requires mixing time of 3 min，4 min for desorption balance.Butyl xanthate adsorbed on the mineral surface with conditions of sodium sulphide dosage of 100 g/t，pH of 9，50 ℃.Infrared spectrum analysis show that hydrophobic materials such as xanthate copper is generated on the malachite surface，and adsorption form is mainly chemical adsorption of ion exchange adsorption. |
