摘要/Abstract

摘要： 四川某硫化铅锌矿石属低品位高钙型难选矿石,铅、锌品位分别为1.41%和8.12%,主要以硫化物形式存在。由于铅品位低、含钙脉石矿物含量高,常规浮选难以实现铅锌有效分离回收。为实现该矿石的高效开发利用, 开展了浮选分离试验。采用优先浮选工艺,以自主研发的YTH为捕收剂,硫酸锌和亚硫酸钠为组合抑制剂,通过浮选条件试验确定工艺流程和药剂制度。结果表明,采用“优先浮铅—铅尾矿再选锌”全流程闭路试验,铅、锌浮选均采用 1次粗选、1次扫选和3次精选,可获得铅品位63.57%、铅回收率75.52%、钙含量0.19%的铅精矿,以及锌品位 57.37%、锌回收率73.62%、钙含量0.74%的锌精矿。该工艺实现了低品位高钙型硫化铅锌矿石的有效开发利用,可为同类型矿石的实际生产提供指导。

Abstract: A lead-zinc sulfide ore from Sichuan is a low-grade,high-calcium refractory ore,with lead and zinc grades of 1.41% and 8.12%,Respectively;Lead and zinc mainly occur as sulfides.Due to the low lead grade and high content of calci um-bearing gangue minerals,conventional flotation cannot achieve effective separation and recovery of lead and zinc.To achieve efficient development and utilization of this ore,flotation separation tests were carried out.A preferential flotation process was a dopted,with self-developed YTH as the collector and zinc sulfate and sodium sulfite as combined depressants.The process flowsheet and reagent regime were determined through flotation condition tests.The results showed that a full-process closed circuit test using the flowsheet of "preferential lead flotation and zinc flotation from lead flotation tailings",in which both lead and zinc flotation adopted one roughing,one scavenging,and three cleaning stages,yielded a lead concentrate with a lead grade of 63.57%,a lead recovery of 75.52%,and a calcium content of 0.19%,as well as a zinc concentrate with a zinc grade of 57.37%,a zinc recovery of 73.62%,and a calcium content of 0.74%.This process achieved the effective development and u tilization of low-grade,high-calcium lead-zinc sulfide ore and can provide guidance for the industrial production of similar ores.
