摘　　要：针对四川某高铁氧化铅锌矿进行了优先浮选、脱泥浮选、摇床重选和强磁选等选矿工艺的条件试验和全浮选工艺流程研究,通过试验得到了铅品位72.59%、铅回收率60.19%的硫化铅精矿;锌品位51.83%、锌回收率12.23%的硫化锌精矿;铅品位59.90%、铅回收率28.78%的氧化铅精矿;锌品位29.09%、锌回收率41.86%的氧化锌精矿。氧化铅浮选采用脱泥浮选可以较大幅度地降低硫化钠的用量,氧化锌矿物的选别采用摇床重选-强磁选联合流程,可以有效消除弱磁性铁矿物对氧化锌精矿品位的影响。各种铅锌矿物得到了有效回收。The study on conditional experiments of beneficiation technology,including selective flotation,desliming flotation,gravity separation by shaking table and high intensity magnetic separation etc,and bulk flotation process is carried out for an oxidized lead-zinc ore with high iron content in Sichuan province.After the experiments,the lead sulfide concentrate can be get with 72.59% lead grade and 60.19% lead recovery;the zinc sulfide concentrate can be get with 51.83% zinc grade and 12.23% zinc recovery;the oxidized lead concentrate can be get with 59.90% lead grade and 28.78% lead recovery;the oxidized zinc concentrate can be get with 29.09% zinc grade and 41.86% zinc recovery.Desliming flotation can be adopted for oxidized lead mineral flotation to greatly reduce the dosage of sodium sulfide;for oxidized zinc mineral processing,the combined process,gravity separation by shaking table-high intensity magnetic separation can be adopted to remove the effect of low magnetism mineral on the grade of oxidized zinc concentrate.All kinds of lead-zinc mineral were recovered effectively.
