内蒙某复杂多金属硫化矿含铜、铅、锌、银等有价金属，铜铅混浮的尾矿仍含锌硫．针对铜铅混浮尾矿的矿石性质，采用“锌硫混浮-锌硫分离”的原则流程从铜铅混浮尾矿中回收锌．锌硫混浮时，用硫酸铜作锌矿物的活化剂，用丁黄药作捕收剂，其精选为空白精选；锌硫分离时，添加石灰和适量水玻璃抑制硫化铁矿和石英等硅酸盐脉石．在给矿锌品位为1．55％时，获得锌精矿品位46．30％、回收率90．92％的试验指标，硫得到综合回收．

A tailing was obtained from a Neimeng polymetallic sulfide ore ,which was composed of copper , lead ,zinc ,silver and other valuable metal by copper-lead bulk flotation .It remains to be valuable for the zinc and sulfur .According to the characteristics of tailing ,a process of zinc-sulfur bulk flotation and sepa-ration were used to recovery the zinc .In the zinc-sulfur bulk flotation ,copper sulfate was added as an acti-vator of zinc ,while the sodium butyl xanthate was utilized as a collector of sulfide ore and zinc ,and the lime and sodium silicate as the depressors of sulfide ore .When the feeding contained 1 .55% of zinc ,a Zn concentrate with grade 46 .30% and recovery rate 90 .92% was obtained ,in addition ,the sulfur was com-prehensively recovered as w ell .
