新疆某磁铁矿石含TFe 27.30%,S 2.80%,磁铁矿嵌布粒度微细,硫主要以黄铁矿和磁黄铁矿为主,且与磁铁矿关系密切,属于难处理含硫磁铁矿。根据矿石性质,确定采用预先抛尾—磁选—反浮选脱硫的工艺流程,最终获得了TFe品位65.68%、铁回收率71.18%、硫含量0.25%的铁精矿,该工艺为同类型高硫磁铁矿的处理提供了思路。

A refractory magnetite ore in Xinjiang contains pyrrhotite with the content of TFe 27 . 30% and S 2 . 80%. Pyrrhotite that mineral dissemination particle sizes was fine was closely connected with sulfur which were mainly composed of pyrite and aikinite. The technological process of pre-concentration for discarding gangue minerals, magnetic separation and reverse flotation for desulfuration was determined according to the ore properties, and a final iron concentrate containing 65. 68%, a recovery of 71. 18%, with a S content of 0. 25% was obtained.
