issues surrounding exploiting metal ores

Final Report Summary

A further issue with using existing toxicity data to regulate mining activity is that many assessments of metal toxicity are based on a single metal presented at a single oxidation state. Mineral ores comprise complex mixtures of metals that are site-specific (e.g. Knight et …

Keeper man (2000) defined quarrying as an act of exploring and exploiting stone from rocks. Metal ores are extracted by mining which involves removal of rock from the ground. The difference between mining and quarrying is that quarrying extracts nonmetallic rocks and aggregates while mining excavates the site for metallic mineral deposits (Banez, et al., 2010).
