用分子力学方法对Cu2＋与闪锌矿作用以及Cu2＋作用后闪锌矿表面与丁基黄药相互作用进行模拟和计算,结果表明：Cu2＋对闪锌矿起到很好的活化作用,Cu2＋在闪锌矿表面的活化机理是发生键合作用;Cu2＋活化后,丁基黄药同时吸附在闪锌矿表面Cu和Zn原子上。浮选试验和XPS测试结果验证了分子模拟所推出的结论,分子力学模拟方法可以较好解释矿物浮选作用机理。
用分子力學方法對Cu2＋與閃鋅礦作用以及Cu2＋作用後閃鋅礦錶麵與丁基黃藥相互作用進行模擬和計算,結果錶明：Cu2＋對閃鋅礦起到很好的活化作用,Cu2＋在閃鋅礦錶麵的活化機理是髮生鍵閤作用;Cu2＋活化後,丁基黃藥同時吸附在閃鋅礦錶麵Cu和Zn原子上。浮選試驗和XPS測試結果驗證瞭分子模擬所推齣的結論,分子力學模擬方法可以較好解釋礦物浮選作用機理。

By molecular mechanics simulated and caculated the action between Cu2＋ and sphalerite,the interaction of the surface of sphalerite after the action of Cu2＋ with butyl xanthate.The results show that Cu2＋ can activate the flotation of sphalerite,the adsorption of Cu2＋ on sphalerite may be regarded as chemical adsorption,after sphalerite activated by Cu2＋,copper and zinc have interacted with butyl xanthate.Flotation tests and XPS analysis verify the conclusions made by molecular mechanics,and prove that molecular mechanics method can be used to reveal the activation mechanism of mineral flotation.
