Abstract: Original potential flotation (OPF) technology, which controls potential by chemical atomsphere resulted from various redox reactions in grinding flotation system, but neither through the use of redox reagents nor through the application of potentials from an external source, was proposed. For lead zinc iron sulphide minerals flotation system, the relationship among technological parameters such as pH, Eop , collectors and flotaion time, was studied. The optimum conditions for the selective flotation of galena from the pb Zn Fe sulfide ores were: pH of 12.5～12.8,the pulp potential of 150～180 mV and with diethyldithioncarbamate (DDTC) as collector.
