摘要: 广东大尖山某铅锌多金属矿石铅品位为2.10%、锌品位为3.805%、银含量为35.85 g/t。矿石铅、锌均主要是以硫化矿的形式存在,硫化铅和硫化锌分别占总铅和总锌的95.71%和95.84%。为给该矿石开发利用提供依据,进行了选矿工艺试验。结果表明:矿石磨细至-74 μm占80%,以CaO为矿浆pH调整剂、硫酸锌为抑制剂、丁胺黑药+丁黄药为捕收剂,经1粗3精4扫铅浮选,铅浮选尾矿以CaO为矿浆pH调整剂、CuSO4为活化剂、丁黄药为捕收剂,经1粗3精4扫锌浮选,获得了铅精矿铅品位60.29%、铅回收率92.02%、含银826.13 g/t、银回收率72.75%、含锌3.64%,锌精矿锌品位48.32%、锌回收率92.30%、含铅0.95%的指标。

Abstract: There is 2.10% Pb,3.805% Zn,and 35.85 g/t Ag in a lead-zinc polymetallic ore in Dajianshan of Guangdong.Lead and zinc mainly exists in form of sulfide minerals,lead sulfide and zinc sulfide accounts for 95.71% and 95.84% of total lead and total zinc,respectively.To provide technique basis for development and utilization of the ore,beneficiation experiment was conducted.Results indicated that,at grinding fineness of 80% passing 74 μm,using CaO as pulp pH regulator,zinc sulfide as depressor,ammonium dibutyl dithiophosphate + butyl xanthate as collector,via two roughing three cleaning four scavenging flotation,tailings of lead flotation using CaO as pulp pH regulator,CuSO4 as activator,butyl xanthate as collector,via one roughing three cleaning four scavenging flotation,lead concentrate with 60.29% Pb,recovery of 92.02%,826.13 g/t silver,recovery of 72.75%,3.64% Zn,Zinc concentrate with 48.32% Zn,recovery of 92.30%,and 0.95% Pb was obtained.
