2014-5-13 · Iron ore is mined, crushed and separated into lump and fines components, which are sold as separate products. Quality (and therefore value) depends upon the shipped composition of each product matching a target composition vector, in iron and in several other minerals. Each day, ore is selected for mining to meet these target grades.
Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are 3.23 and 3.08, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.
