Why is iron ore important to the economy?
The vast majority of iron ore is used to produce iron which is in turn used to produce steel. 98% of the iron ore mined today is used for steel production. This includes staples, cars, and steel beams used in the construction of buildings and just about anything else where iron and steel are needed.
What are the effects of mining iron?
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.
What are the negative economic impacts of mining?
