【摘要】 采用X射线光电子能谱 (XPS)研究了Cu2 + 和Pb2 + 在几种硅酸盐矿物表面的吸附规律 ,及矿物表面元素在金属离子及捕收剂油酸钠吸附前后电子结合能和相对含量变化 ,结合矿物在金属离子作用前后可浮性的变化 ,分析了金属离子和捕收剂在不同硅酸盐矿物表面的吸附规律。更多还原

【Abstract】 Adsorption law of Cu 2+ and Pb 2+ on surface of some kinds of silicate minerals have been studied by X ray photoelectron spectrometric (XPS), and electronic binding energy and relative content varieties of mineral surface element have also been researched before and after metal ion and collector sodium oleate are adsorbed, combined with flotability varieties of silicate minerals before and after metal ions are adsorbed, adsorption law of metal ion and sodium oleate on the surface of different silicate minerals have been analyzed.更多还原
