Utilization of high-sulfur iron ore tailings in cement mortar …

Therefore, the graded iron ore tailing (GIOT) was obtained and the particle size distribution of the GIOT was consistent with the SS. The chemical composition of the IOT also was measured by the XRF and X-ray diffraction (XRD) methods respectively (Table 3, Fig. 2). It is evidenced that this IOT is a kind of high-sulfur tailings with the ...
