摘要: 針對國內某高鐵拜耳赤泥的特點進行了深度還原——磁選實驗,探討了還原劑量、添加劑量、還原溫度、還原時間、磨礦細度和磁場強度等不同影響因素對鐵精礦品位和回收率的影響.通過化學多元素分析、X射線衍射分析、掃描電鏡和能譜分析等方法,確定了原赤泥及所得鐵精礦的物相組成和特點.在不采用添加劑時,所得鐵精礦的品位為85.66%,回收率為91.86%;采用添加劑時,所得鐵精礦的品位為91.23%,回收率為93.13%.

Abstract: Based on the characteristics of some Bayer red mud, deep reduction-magnetic separation experiments were done to study the effects of influencing factors such as reductant dosage, additive quantity, reduction temperature, reduction time, grinding fineness and magnetic field intensity on the grade of iron ore concentrate and the iron recovery rate. The phase compositions and char-acteristics of red mud and iron ore concentrate were determined by chemical analysis, X-ray diffraction (XRD), scanning electron mi-croscopy (SEM) and energy dispersive spectroscopy (EDS). It is shown that the grade of iron ore concentrate is 85.66% and the iron recovery rate is 91.86% without any additive. When the additive is used, the grade of iron ore concentrate is 91.23% and the iron recovery rate is 93.13%.
