云南某复杂硫、氧混合铅锌矿浮选实验研究

Flotation of Mixed Sulfide⁃Oxide Lead and Zinc Ore from Yunnan

对云南某地新开采硫、氧混合铅锌矿进行了浮选工艺实验研究。采用混合浮选硫化矿及氧化矿的工艺流程,获得了铅综合回收率85.18%、锌综合回收率95.46%的铅锌混合硫化精矿和氧化精矿,其中,硫化铅锌精矿中锌、铅品位分别为46.14%、7.86%;氧化铅锌精矿中铅、锌品位分别为12.71%、6.01%。浮选所得精矿满足冶金过程对原料的要求。研究成果可为浮选此类矿物提供参考依据。

An experimental study was carried out on flotation process of a newly mined mixed sulfide⁃oxide lead and zinc ore from Yunnan Province.By adopting a bulk flotation flow for the mixed sulfide⁃oxide ore,a mixed lead⁃zinc sulfide concentrate and a lead⁃zinc oxide concentrate were floated,with the total lead recovery of 85.18%and total zinc recovery of 95.46%.Among them,the lead⁃zinc sulfide concentrate graded 46.14%Zn and 7.86%Pb,while the lead⁃zinc oxide concentrate graded 12.71%Zn and 6.01%Pb.The flotation concentrates can meet the requirements of metallurgical process for raw materials.This research provides a reference for the succeeding flotation practice of such ores.
