摘　　要：某难选高硫锌矿石具有性质复杂、有用矿物种类多的特点,采用两步混合浮选锌硫-锌硫分离及磁选工艺流程,使不同可浮性的锌硫矿物分别得到了有效回收,为后续锡的选别创造了良好条件。在小型闭路试验最终可以得到可获得Zn品位43.59%、Zn回收率89.67%的锌精矿;硫品位34.97%、硫回收率61.49%的硫精矿。A ore property of refractory high sulfur zinc ore is complicated and valuable minerals are of various types. The technological process with zinc and sulfur two-step bulk flotation-separation and magnetic process is adopted., which brings the different zinc and sulfur minerals with different floatability are recoveryied respectively and creats a good condition for posterior tin separation. The closed-circuit test can obtain a zinc concentrate having a zinc content of 43.59% and recovery of 89.67% and a sulfur concentrate having a sulfur content of 34.97% and recovery of 61.49%.
