The invention discloses a beneficiation method for a complex sulfide ore containing marmatite. The beneficiation method comprises the following steps that a raw ore is ground and subjected to magneticseparation, so that the marmatite and magnetic separation tailings are obtained; zinc flotation is carried out on the marmatite so as to obtain a zinc concentrate; and sequential priority flotation is conducted on the magnetic separation tailings. According to the method, not only the zinc content in a copper (lead) concentrate is greatly reduced, the zinc recovery rate is improved, but also theusing amount of a flotation reagent is reduced, and the pollution to the environment is reduced. 本发明公开了一种含铁闪锌矿的复杂硫化矿选矿方法，包括：对原矿进行磨矿，并进行磁选，从而得到铁闪锌矿和磁选尾矿；对所述铁闪锌矿进行锌浮选，从而得到锌精矿；对所述磁选尾矿进行顺序优先浮选。本发明不仅大大降低了铜(铅)精矿中的锌含量，提高了锌回收率，而且降低了浮选药剂的使用量，减少了对环境的污染。
