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 erosion and effect the soil profile and sometimes minor particles of.
In a decision that could be a big boost for iron ore miners in the country the Ministry of Mines has assured that the mining sector will become the most thriving sector for business in India But the tribal affairs minister Jual Oram has opposed iron mining in his own constituency in Odisha.
Iron is one of the most mined element among the metals Most of the iron ore mines exists in dense forest zones The activities carry to extract Iron Ore consists of blasting excavation loading dumping crushing screening and transportation which emits great amount of air pollutants to environment Pollutants resulted from the anthropogenic activities effects both biotic and abiotic.
The iron ore induration or pelletizing process emits particulates sulfur dioxides (SOx) nitrogen oxides (NOx) and other pollutants depending on trace elements in the orebody and fuel Typical emission levels for these compounds during induration will be outlined and corresponding options for pollution control equipment described Recent pellet plant construction in Sweden and the United.

The present study was carried out in a Swedish iron ore mine where all mining since the 1920s has been carried out underground The dominant mode of mining is sublevel caving Diesel powered engines were introduced into the mine in the mid 1960s The air pollution in the investigated mine was complex.
Underground mining has the potential for tunnel collapses and land subsidence (Betournay 2011) It involves large scale movements of waste rock and vegetation similar to open pit mining Additionally like most traditional forms of mining underground mining can release toxic compounds into the air.
Iron mining operations began on the Mesabi Range in 1884 where strip mining was the most common method used to gain access to the ore The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today As the rich ore was depleted taconite mining operations began.
