Iron Ore Mining Water Pollution

Iron Ore Mining Water Pollution

The iron ore limestone and coke are charged heated and then reacted to form a reducing gas which reduces the iron oxide to metallic iron The iron is tapped from the furnace along with the slag which contains the impurities Many foundry air pollution problems are similar to those of steel mills but on a smaller scale Potential The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide carbon dioxide carbon monoxide and sulfur dioxide from diesel generators trucks and other equipment The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines
