Environmental Strategies in the Mining Industry: One
During mining, metal-bearing rock called ore is extracted from underground or surface mines. Metal concentrations in ore vary greatly, from less than 1 percent by weight for most gold deposits to over 60 percent for some iron ore deposits; most metallic mineral deposits have ore grades in the range of 1–5 percent by weight.
