摘要/Abstract

摘要： 湖北某低品位铅锌矿铅品位为0.76%，锌品位为1.37%。铅元素主要赋存于方铅矿、索硫锑铅矿和白铅矿中；锌元素则主要赋存于闪锌矿中。脉石矿物主要为白云石、石英。采用磨矿条件试验和正交试验确定的试验条件，在磨矿细度为-0.074 mm占75%条件下，采用1粗2精1扫选铅，选铅尾矿 1 粗 2 精 1 扫选锌闭路流程试验，得到铅品位为 45.72%、回收率为 80.25% 的铅精矿，锌品位为 45.44%、回收率为91.02%的锌精矿，实现了铅、锌的高效分离，获得了合格的铅精矿和锌精矿产品。

Abstract: The lead grade of a low-grade lead-zinc ore in Hubei is 0.76%，and the zinc grade is 1.37%. The lead element mainly occurs in galena，sulfur antimony lead ore and cerussite，zinc mainly pres⁃ ents in sphalerite. Gangue minerals are mainly dolomite and quartz. The experimental conditions determined by grinding conditional test and orthogonal test were adopted. Under the conditions that the grinding fineness was -0.074 mm accounting for 75%，the lead was separated by one roughing，two cleanings and one scav⁃ enging，and the lead tailings were separated by one roughing，two cleanings and one scavenging zinc selec⁃ tion closed-circuit process test. The lead concentrate with lead grade of 45.72% and recovery rate of 80.25% and the zinc concentrate with zinc grade of 45.44% and recovery rate of 91.02% were obtained. The efficient separation of lead and zinc was realized，and qualified lead concentrate and zinc concentrate products were obtained.
