Mine tailings -- the remnants of materials left behind after the desired mineral is extracted -- are often simply piled on-site while a mine is in operation and left behind when the mine is abandoned. These tailings are often toxic, and when rain runs off the piles, it leaches out ...

2007). High use of copper and nickel, in batteries and electric motors, and copper and gold, in power electronics, increase disposal of mine tailings containing sulfides (Classen et al. 2009). Consequently, improved waste handling in the mining industry and a less coal-dependent energy mix ...

In consequence, one can see a general trend if one plots exploration expenditures against R/P-ratios (Wellmer and Becker-Platen2002, p.731 and Fig.9). If R/P-ratios are low, as for gold or copper, the expenditures are high; they are much lower when the ratios are high as for the...

The values of these parameters are mainly based on the data of metal mines, especially gold mines. The specific parameter determination processes are provided below, and the raw data can be found in the Supplementary Materials. Tailing storage is the conventional approach to handling tailings in ...
