Sources of pollution: mining. ... Acidic drainage and the leaching of metals from the mine workings and mine wastes may occur at metal mines. Acidic drainage can cause significant impacts on water quality and aquatic ecosystems. Chemicals that are used to process metalbearing ores can also be found in mine waste water.
1. INTRODUCTION Sources of air pollution in the iron and steel industry Whenever reference is made to air pollution caused by the iron and steel industry, this relates often only to the contamination of the outdoor atmosphere with which the general public is familiar in the form of dust
Dust types which are a particular nuisance originate from coal and iron ore mining. These cause discolouration, and in some cases permanent damage. In the case of iron ore, these types of impacts occur near the operations, shipping zones, and particularly in the vicinity of material handling or transfer points associated with these.

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfurcontaining materials in the presence of water leads to highly acidic solutions.

The Iron and steel Industry has significant impact on global environment. Producing steel requires the use of large quantities of energy and minerals, as well as vast mining and waste disposal areas. As a result, steel production generates significant amount of air pollutants, solid byproducts and residues, as well as waste water sludge.
In fact, the industrial revolution in Europe started with coal mining in the United Kingdom, and the iron and steel industry prospered paralleling the growth of the coal industry; coking coal being an essential input to steel metallurgy. The superpowers of today, the USA, China, and Russia, have immense reserves of both iron ore and coal.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
Due to the irregular operation of mining, it has caused irreversible damage to the environment. Mining produces a lot of chemicals, causing serious pollution to air, soil and water resources. Air pollution. Underground mining is a common method of mining. In the process of mining, drilling and blasting are usually used to underground mining.
