In order to change the current situations that iron grade of flotation tailings is higher and loss of ferrous metal is great in the complex process of iron separation of ore grinding, weak magnetic separation-high intensity magnetic separation-flotation, the recycling process of ore grinding-magnetic separation is adopted for flotation tailings. The contrast test for recovery of magnetic separation with single variable is carried out with different ore grinding modes (ball mill and attrition mill) and flotation tailings of different granularities. With the increase of proportion of fine minerals, the yield of magnetic concentrate is decreased from 76.73% to 48.78%, grade is increased from 38.1% to 61.15% and recovery rate is decreased from 86.20% to 78.29% after grinding flotation tailings by attrition mill. The yield of magnetic iron concentrate is decreased from 78.05% to 56.63%, grade is increased from 38.10% to 55.78% and recovery rate is decreased from 92.80% to 82.92% after grinding flotation tailings by ball mill under the same magnetic separation conditions.

在磨矿、弱磁-强磁-浮选复杂选铁流程中,为了改变浮选尾矿铁品位较高、铁金属量损耗大的选铁工艺流程现状,对浮选尾矿采用磨矿-磁选再回收工艺,采取不同磨矿(球磨、艾砂磨)方式、不同粒度浮选尾矿进行单一变量的磁选回收对比试验。浮选尾矿经艾砂磨机磨矿后,随着细粒级矿物占比的提高,磁选精矿产率由76.73%下降至48.78%,品位由38.1%上升至61.15%,回收率由86.20%降低至78.29%。浮选尾矿经球磨机磨矿后,在相同磁选条件下,磁选铁精矿产率由78.05%下降至56.63%,品位由38.10%上升至55.78%,回收率由92.80%降低至82.92%。

在磨矿、弱磁-强磁-浮选复杂选铁流程中,为了改变浮选尾矿铁品位较高、铁金属量损耗大的选铁工艺流程现状,对浮选尾矿采用磨矿-磁选再回收工艺,采取不同磨矿(球磨、艾砂磨)方式、不同粒度浮选尾矿进行单一变量的磁选回收对比试验。浮选尾矿经艾砂磨机磨矿后,随着细粒级矿物占比的提高,磁选精矿产率由76.73%下降至48.78%,品位由38.1%上升至61.15%,回收率由86.20%降低至78.29%。浮选尾矿经球磨机磨矿后,在相同磁选条件下,磁选铁精矿产率由78.05%下降至56.63%,品位由38.10%上升至55.78%,回收率由92.80%降低至82.92%。

In order to change the current situations that iron grade of flotation tailings is higher and loss of ferrous metal is great in the complex process of iron separation of ore grinding, weak magnetic separation-high intensity magnetic separation-flotation, the recycling process of ore grinding-magnetic separation is adopted for flotation tailings. The contrast test for recovery of magnetic separation with single variable is carried out with different ore grinding modes (ball mill and attrition mill) and flotation tailings of different granularities. With the increase of proportion of fine minerals, the yield of magnetic concentrate is decreased from 76.73% to 48.78%, grade is increased from 38.1% to 61.15% and recovery rate is decreased from 86.20% to 78.29% after grinding flotation tailings by attrition mill. The yield of magnetic iron concentrate is decreased from 78.05% to 56.63%, grade is increased from 38.10% to 55.78% and recovery rate is decreased from 92.80% to 82.92% after grinding flotation tailings by ball mill under the same magnetic separation conditions.

因白云鄂博矿矿物种类多,矿石性质复杂,嵌布粒度细[1-4],目前对铁的反浮选尾矿回收所使用的工艺流程相对较长,并且较为复杂,矿物回收率较低,造成极大浪费,已经无法满足目前白云鄂博矿选矿生产要求。随着矿产资源的开发利用,白云鄂博矿尾矿堆存问题已经越来越引起重视[5],因此改进工艺流程是当前的重点。对浮选尾矿中的铁矿物进行回收利用,可缓解尾矿堆存引发的环境问题,减少稀有资源的流失,进而减少环境负荷,推动经济社会的可持续发展。
本次试验将白云鄂博矿经磨矿、弱磁-强磁-浮选工艺流程分选后的浮选尾矿作为试验的原矿。表1为矿石多元素分析结果。
表1可得,原矿铁品位为38.1%,具有较高的回收价值,只针对回收铁精矿,其原矿中S、F等杂质含量较高,且将铁回收后会减少铁对后续其他有用矿物回收产生的不利影响。
对试验原矿采用化学测试、光学显微镜等方法进行矿物组成和铁矿物物相分析,分析结果见表2表3
表2浮选尾矿物组成分析可以看出,原矿中存在着可回收利用的矿物以铁矿物为主,占比为41.30%,其中无磁性的萤石、白云石、硅酸盐矿物等矿物占比为43.62%,弱磁性稀土矿物占比为15.08%。
表3浮尾矿铁矿物物相分析可以看出,浮选尾矿中铁矿物以Fe-磁铁矿为主,占总铁矿物的93.57%,白云鄂博矿具有贫、细、杂的特点,矿石嵌布复杂,矿物粒度细且共生关系紧密,传统的磨矿方式难以有效解离有用矿物。因此,探索不同的磨矿方式以改变矿石的嵌布特性,提高矿物解离度和选矿效率,具有重要意义。
采用1 kg球磨机和ALC-1.5L艾砂磨对其进行磨矿试验,采用XCGS-50磁选管对矿物进行单一变量磁选试验,试验方法见图1
依照包钢宝山选矿厂对白云鄂博矿中铁矿物弱磁-强磁分选条件,本次试验固定磨矿浓度为30%,磁选管的磁场强度为1 800 Oe,改变磨矿时间,对不同磨矿方式下生产出的相同粒度的原矿进行磁选条件试验,试验结果见图2图3
图2可知,浮选尾矿经艾砂磨磨成不同粒度,在磁选试验中,磁选精矿品位随着细粒级矿物占比增加而提高,回收率随着细粒级矿物占比增加而降低。粒度从45 μm下占81%磨至45 μm下占97%的条件下,磁选精矿品位与回收率变化幅度较大,品位提高了32.01%至56.5%,回收率降低了5.17%至81.74%;磨矿粒度至25 μm下占90%后,经磁选后磁选精矿品位与回收率呈稳定趋势,在磨矿粒度为25 μm下占98%条件下,可得品位为61.15%、回收率为78.29%的磁选精矿。
图3可知,浮选尾矿经球磨磨成不同粒度,在磁选试验中,在粒度38 μm下占97%之后,随着细粒级矿物占比继续增加,磁选精矿品位与回收率呈稳定趋势,最终精矿产率由78.05%下降至56.63%,精矿品位由38.1%提高至55.78%,回收率由92.8%下降至82.92%。
抽取4组不同粒度磁选精矿测定主要杂质F、P的含量,测定结果见表4
当筒体旋转时,球磨机的研磨介质会随着筒体上升到一定高度,在重力作用下自由下落,产生冲击力破碎物料;当搅拌器高速旋转时,艾砂磨带动研磨介质在筒体内做剧烈的圆周运动,研磨介质之间相互碰撞、摩擦,并且不断与物料颗粒接触,使物料在这种强烈的搅拌作用下被粉碎。在相同磨矿粒度的条件下,艾砂磨较球磨可以更好地打开矿物当中的包裹体、连生体,有利于单体目的矿物回收,无用杂质的抛出。
表4可知,随着细粒级矿物的增加,在球磨磁选管精矿中,P含量呈下降趋势,相比原矿品位降低27.5%,由于F在矿物中嵌布粒度较细,球磨无法将其连生矿物打开,因此F含量呈现先下降后趋于稳定的趋势,相比原矿品位降低61.2%,但在艾砂磨磁选管精矿中F、P含量一直呈下降趋势,P含量相比原矿降低47.5%,F含量相比原矿降低85.4%。
结合磁选管所得铁精矿的品位、回收率和所含杂质F、P含量,对两种磨矿方式(球磨、艾砂磨)所得粒度在38 μm下占比97%的矿样进行粒级筛分,筛分结果见表5
表5筛分结果可知,在球磨和艾砂磨两种不同磨矿模式下,粒度在38 μm以下占比97%相同粒度条件下,经过艾砂磨之后的浮尾矿物粒度在<25 μm粒级范围相比球磨高19.5个百分点。在相同磨矿粒度不同磨矿方式下,经艾砂磨后的浮尾矿物解离度较高。
(1)对浮选尾矿进行不同磨矿(球磨、艾砂磨)方式的磁选对比试验,在粒度25 μm下占比98%条件下分别可得铁品位为55.78%和61.15%的磁选精矿。
(2)随着细粒级矿物占比的增加,目的铁矿物单体解离度升高,改善了杂质矿物在磁选分选过程中对于目的矿物选别的不良影响,在粒度25 μm下占比98%的条件下,磁选精矿中(球磨、艾砂磨)P品位与原矿相比分别下降至0.29%与0.21%,F品位与原矿相比分别下降至2.60%与0.98%。
(3)根据粒度筛分试验结果分析可得,在相同粒度下,经艾砂磨机磨矿后矿物的细粒级占比高于球磨机,更适用于在磨矿-磁选简单选别流程中对浮选尾矿目的铁矿物的回收利用和杂质矿物的抛除。
