摘要 在本研究中，研究了磁化焙烧后磁选的工艺，用于从高钙型含锡铁尾矿（含 35.53 wt.% Fe 和 0.56 wt.% Sn）中分离或回收锡和铁。在无烟煤配比2.5:100、焙烧温度850℃、焙烧时间30 min、磨矿时间10 min、磁场强度0.1 T的最佳条件下，得到含铁66.3%、锡0.07%、铁回收率92.9%的磁精矿。采用X射线粉末衍射、扫描电镜-能谱等手段研究了SnO2的相变。
ABSTRACT In this study, a process of magnetizing roasting followed by magnetic separation, which is used to separate or recover tin and iron from the high calcium type tin- and iron-bearing tailings (containing 35.53 wt.% Fe and 0.56 wt.% Sn), was investigated . A magnetic concentrate containing 66.3 wt.% Fe and 0.07 wt.% Sn with an iron recovery rate of 92.9 wt.% was obtained under optimal conditions: anthracite ratio of 2.5:100, roasting temperature of 850°C, roasting time of 30 min, grinding time of 10 min, and magnetic field intensity of 0.1 T. In addition, the effect of roasting parameters on the separation of iron and tin and phase transformation of SnO2 was investigated by using X-ray powder diffraction, Scanning Electron Microscopy–Energy Dispersive Spectroscopy, etc.
