摘　　要：针对四川某氧化锌矿锌含量偏低、氧化程度较深,泥化严重的特点,提出了"硫化锌优先浮选-尾矿摇床脱泥-氧化锌硫化浮选"工艺流程。在原矿锌品位为1.45%时,可获得锌品位38.42%、锌回收率32.63%的硫化锌精矿和锌品位31.24%、锌回收率35.73%的氧化锌精矿,所得硫化锌精矿及氧化锌精矿累计锌品位为34.30%,锌回收率为68.36%,取得了较理想的选矿指标。To recover a highly oxidized and slimed zinc oxide ore with low content of zinc from Sichuan Province,a technological flowsheet was introduced consisting of preferential flotation of zinc sulfide,desliming by tabling and sulfuration flotation of zinc oxide.From a run-of-mine ore with a zinc grade of 1.45%,a zinc sulfide concentrate with zinc grade and recovery of 38.42% and 32.63%,respectively,and a zinc oxide concentrate with zinc grade and recovery of 31.24% and 35.73%,respectively,were prepared,and the total zinc grade and recovery were 34.30% and 68.36%,resulting in good separation index.
