甘肃某含钛磁铁矿选矿试验研究

Experimental study on mineral processing of a titaniferous magnetite ore in Gansu

  • 摘要: 甘肃某含钛磁铁矿含钛6.58%,含铁21.46%,具有较大的回收价值.在工艺条件试验研究的基础上,采用"弱磁选铁-强磁预富集-钛浮选"的工艺流程回收有价金属,最终,实验室小型闭路试验可获得含铁61.75%,全铁回收率43.45%(磁性铁回收率达86.47%)的铁精矿和含钛50.10%,钛回收率60.23%的钛精矿,浮选作业回收率为85.94%,选别指标较好.

     

    Abstract: A titaniferous magnetite ore in Gansu has great recycling value which contains 4.10% of titanium and 20.25% of iron. Based on the experimental study on process conditions, the process of "iron low intensity magnetic separation-high intensity magnetic preconcentration-titanium flotation" was adopted in the recovery of useful metals. Finally, the small close circuit test obtain the iron concentrate with 61.75% of iron and 43.45% of full iron recovery rate (with magnetic iron recovery rate of 86.47%), and the titanium concentrate with 50.10% of titanium and 60.23% of titanium recovery rate, as well as the flotation recovery of 85.94%. The separation indexes are ideal.
