Sulfur Tailing Sampling


Geochemical characterization of dust from arsenic-bearing ...

Data for the 22 tailings samples show that arsenic exhibits the best positive correlation with sulfur (R 2 = 0.86), followed by antimony (R 2 = 0.69) and iron (R 2 = 0.68). These data suggest that the arsenic in the near-surface tailings at Giant mine are primarily associated with sulfide minerals, and to a lesser extent iron-bearing phases.

Mine Tailings Sampling Technique - Laboratory Testing ...

Your suggestion is highly relevant. 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.
