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.
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 and43.45 % 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.
