Environmental impact of iron ore mining
When iron ore mining exposes metal-bearing ores rather than exposing ore bodies naturally through erosion, and when mined ores are placed on earth surfaces in mineral dressing processes, the risk of contamination increases. [14] Public Safety [ edit] People are naturally drawn to old mining sites, but they can also be dangerous.
