The lead-zinc mill tailings differ from other materials used in previous studies in terms of host rock type (lead-zinc tailings are of calc-silicate dolomite and graphite mica schist) and physico-chemical properties. These properties have a direct impact on the mechanical properties/strength development of paste backfill materials [20,37,43,44].

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.
