The common mining practice until very recently could be summarized in a few steps: from obtaining a license, dig the ore, sell the metal, and, once the deposit was exhausted, walk-away and start another mine elsewhere (Jain et al. 2016; EB 2017 ). Not surprisingly, mining is among the human activities with widest environmental and social impacts.
