Environmental impact of iron ore mining
Water is one of the major natural resources that is being polluted by iron ore mining operation. Pollution reduces with increasing distance away from the iron ore mining sites. [13] Metals are leached out, and acid water carries them downstream to the sea in sloppy regions. Water bodies are polluted during iron ore mining operations.
