摘　　要：某铁铜铅锌原矿含铁25．70％，其中磁铁矿和磁黄铁矿中铁分别占总铁的58．33％和517％。在铜、铅和锌矿物顺序优先浮选后，采用磁选方法从尾矿中选铁，所得铁粗精矿因含硫2％～3％而不达销售标准。通过浮选脱硫-磁精选工艺，得到了含Fe 64.61％、S 0．32％的合格铁精矿。A iron-copper-lead-zinc ore contains 25.70% iron, there are 58.33% and 5.17% of iron contributed in magnetite and pyrrhotite separately. Magnetic separation is adopt to recover iron from the railings of copperlead-zinc flotation, but the iron rough concentrate is unqualified for it contains 2% -3% S. Desulphurization-magnetic separation technology is followed to obtain a qualified iron concentrate with 64.61% Fe and 0.32% S.
