Characterization and treatment of artisanal gold mine

2008-2-11  The size distribution of the particles of the artisanal gold mine tailings, for samples A and B, are presented in Fig. 3.One remarks that the characteristic diameter that retains half of the particles population (d 50) in both cases is about 150 μm, which characterizes a relatively coarse tailings for a gold ore .It is likely that a larger amount of gold is still locked inside the tailing

Tailing Disposal an overview ScienceDirect Topics

After settling and self-weight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about 1.8 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s. Figures 2.4(a) and (b) show typical wet and dry density and w profiles with depth for
