摘要	The influence of calcium fluoride on the electrochemical dissolution of chalcopyrite at pH 2 was investigated. Experimental results show, when CaF2 concentration from 0 increased to 10 mg/L, chalcopyrite corrosion current density from 0.316 mu A cm(-2) changed to 0.302 mu A cm(-2), the CaF2 inhibition efficiency is 4.43 % and up to 15.19 % when CaF2 is saturated; electrochemical impedance spectroscopy (EIS) reveals that it is the increase of the charge transfer resistance at the double layer lead to CaF2 restrain chalcopyrite corrosion; and the cause come from copper fluorinated complex formed and are absorbed on the electrode surface.
