Sticking mechanism of low grade iron ore-coal composite

2018-11-1  The iron ore with a low iron grade but high SiO 2 was obtained from Qidong area (Hunan, China). As shown in Table 1, the total iron content (T.Fe) was 33.86 wt%, while the content of SiO 2 was 40.61 wt%. Other constitutes included 4.36 wt% Al 2 O 3, 1.57 wt% of CaO, and 1.05 wt% of MgO.XRD pattern shows that hematite, quartz, chlorite and sericite constituted the main phases of this ore.
