Mine Tailings Sampling Technique Laboratory Testing

Tailings are variable by essence with mining and processing. For instance, early Pb-Zn tailings are generally pyrite-poor as pyrite was valorized for sulphur. Since a few decades, pyrite is dumped in tailings, changing radically their composition (and AMD behavior). We should talk of tailings stratigraphy here. Other variations may be observed with depth. On the opposite, the horizontal

Mine Tailings an overview ScienceDirect Topics

Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content. Tailings are transported from the mill and are
