Activation Mechanism of Sphalerite Flotation in the Presence of Cu~（2＋） by Molecular Mechanics
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.
