| Abstract: | The run of mine ore of Fankou Lead-Zinc Mine belongs in high sulfied type lead-zinc minerals The minerals was shown coarse fine inhomogeneous dissemination.pyrite was easy of flotation, lead and iron difficult to separate.Through scientific research,break lead concentration pH value,it was introduced that technique of high alkalinity,fine grinding,mixed collectors,high-speed flotation and new type depressant.The index of concentration economic techniques were improved by a wide margin.The rich practice experiences were provided to separate high lead-zinc sulfide minerals. |
