摘　　要：针对某锌矿石矿物种类复杂、氧化率高、风化严重、含泥量大的特点,采用“硫化锌优先浮选-尾矿脱泥-氧化锌浮选”原则工艺流程回收该矿石中的锌矿物,获得了Zn品位分别为38.42%和31.24%的硫化锌精矿和氧化锌精矿,Zn总回收率为69.14%的试验指标,为该资源的回收利用提供技术依据。Aiming at the characteristics of complex mineral types,high oxidation rate,severe weathering and large mud content of a zinc ore,the principle of"zinc sulfide preferential flotation-tailings desliming-zinc oxide flotation"was adopted to recover zinc minerals from the ore,and zinc sulfide concentrate and zinc oxide concentrate with Zn grades of 38.42%and 31.24%were obtained separately,with a total recovery rate of 69.14%,which was the experimental index for the recovery of this resource.
