Mining environmental liabilities (MEL) are of great concern because potential risks to ecosystems and human health. In this research, the risk (RI) related MEL existing in three artisanal small-scale gold-mining areas Ecuador was evaluated. For purpose, data 167 including landfills, mining galleries, tailing deposits, mineral processing plants from Macuchi, Tenguel–Ponce Enriquez, Puyango areas...

A hot, dry wind envelopes a statuesque woman as she kneels over wind-sifted trays of tinbearing pulverized ore in Uis, Namibia.

The challenge to maximize resource efficiency requires the optimal use of all products leaving a mine—not only ore but also waste products—and calls for contributions from and cooperation with every discipline involved as efficiently possible. These interdisciplinary transdisciplinary interactions between practitioners scientists are an act learning take time. They should be initiated at start ...

Atmospheric mercury emission scenarios from artisanal and small-scale gold mining for 56 tropical subtropical countries have been elaborated assessed their comparative significance. A multi-step quantitative method that yields narrow robust confidence intervals estimates was employed. Firstly, data on production different years, the ratio of used in amalgamation processes, ancillary input param...
