A flowsheet consisting of pre-reduction magnetic roasting and magnetic separation was introduced to process a refractory weakly-magnetic iron ore from Jiangsu Province. The results show that after 60 min roasting at 750 ℃ by adding coal as a reducing agent at an amount of 3%, the pre-reduced iron ore was ground to a fineness of 75% -0.074 mm and then subjected to low intensity magnetic separation consisting of one roughing, one cleaning and one scavenging, resulting in a high quality iron concentrate grading 65.05% Fe at 96.19% recovery. The research results can provide technical reference for the mineral processing of refractory weakly-magnetic iron ore.

对江苏某难选弱磁性铁矿石进行了预还原磁化焙烧-磁选试验研究。结果表明,矿样在预还原反应温度750 ℃、反应时间60 min、还原剂煤用量3%、磨矿细度-0.074 mm粒级占75%条件下,经一粗一精一扫弱磁选,可获得铁品位65.05%、铁回收率96.19%的高品质铁精矿。研究结果可为难选弱磁性铁矿石选别提供一定参考。

对江苏某难选弱磁性铁矿石进行了预还原磁化焙烧-磁选试验研究。结果表明,矿样在预还原反应温度750 ℃、反应时间60 min、还原剂煤用量3%、磨矿细度-0.074 mm粒级占75%条件下,经一粗一精一扫弱磁选,可获得铁品位65.05%、铁回收率96.19%的高品质铁精矿。研究结果可为难选弱磁性铁矿石选别提供一定参考。

A flowsheet consisting of pre-reduction magnetic roasting and magnetic separation was introduced to process a refractory weakly-magnetic iron ore from Jiangsu Province. The results show that after 60 min roasting at 750 ℃ by adding coal as a reducing agent at an amount of 3%, the pre-reduced iron ore was ground to a fineness of 75% -0.074 mm and then subjected to low intensity magnetic separation consisting of one roughing, one cleaning and one scavenging, resulting in a high quality iron concentrate grading 65.05% Fe at 96.19% recovery. The research results can provide technical reference for the mineral processing of refractory weakly-magnetic iron ore.
