| Abstract: | the effect of pyrogallic acid on flotation behavior of sulphide minerals and its interaction mechanism have been studied in this paper. Results show that galena, pyrite, chalcopyrite, sphalerite will be depressed in the presence of pyrogallic acid but arsenopyrite will not. The mechanism of pyrogallic acid depressing sulphide minerals has been discussed by means of HMO calculation, interaction energy and energy band structure. |
