| 摘 要： | 用量子化学的CNDO/2方法,计算了黄药与硫化铜矿物、氧化铜矿物吸附体系简化模型。计算结果表明,黄药与硫化铜矿物的作用比它与氧化铜矿物的作用强。说明黄药对硫化铜矿物的浮选性能好。黄药对氧化铜矿物进行浮选时,需先进行硫化。

| Abstract: | The quantum chemical CNDO/2 method is used for calculating the redu ced model of xanthate adsorption onto the minerals of copper sulphide or ox ide. The results bespeak that the reaction between xanthate and copper sul phide is stronger than that between xanthate and copper oxide, which exp lain the fact that copper sulphide can be well floated by xanthate and that volcanization of copper oxide is definitely necessary prior to its flotation by xanthate. |
