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 erosion and effect the soil profile and sometimes minor particles of iron spread with air cause air pollution. Mining in.
Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium. An important sulfide mineral common in waste rock is pyrite, iron sulfide. When pyrite is exposed to air.
