| A new technology,mineral flotation process,with electrochemi-cal control is used in Xilin Lead-Zinc Mine. Six advantages of the new tech-nology are discussed.The essence of physicochemical model of typical rea- ction,which activated sphalerite by copper ion, was described,It was attem-pted,that several ore types are classified according to acquired data fromthe system,so as to adopt effective reagent addition. |
