According to the characteristics of a low-grade zinc-pyrite-Iron ore,several processing solutions were compared,then detailed reagent condition tests and close-circuit tests were carried on.The results showed that:with adopted pyrite selective flotation-zinc flotation-magnetic separation flowsheet,Zn /S /Fe separation was effectively actualized.A pyrite concentrate with a S grade of 46.51% and a recovery of 93.70% was obtained.Meanwhile,a zinc concentrate with Zn grade and recovery of 47.16% and 55.23%,a iron ore concentrate with Fe grade and recovery of 66.54% and 28.18%,respectively,can be reclaimed.
