Environmental impact due to iron ore mining in Chhattisgarh

Abstract. Iron ore is an important mineral in Chhattisgarh. The production of iron ore is 5.50 million tones per year. Due to massive extraction of iron ore, it pollutes air, water and soil. When iron in solution reaches the water table it pollutes the ground water, while dissolved iron in surface water reacts with soil to cause soil.
