摘要
The effects of mineral processing wastewater on sulfide minerals were investigated by flotation,infrared spectrometry and electrochemistry test. The results show that lead-concentrate water can improve the flotation of galena,while the sulfur-concentrate water has negative effect on flotation of galena compared with distilled water. The flotation behavior of pyrite is contrary to that of galena in three kinds of water. Infrared spectra indicate that the residual collector in the lead-concentrate water is beneficial to the formation of lead xanthate on the surface of galena. Electrochemistry results indicate that electrochemistry reaction on galena surface has apparent change. The anode polarization is improved and cathode polarization is depressed.
