Environmental impact of iron ore mining - Wikipedia

OverviewIssuesIntroduction

The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing, ground excavation, and from equipment t

What Is The Environmental Impact Of The Mining Industry ...

Air PollutionWater PollutionDamage to LandLoss of BiodiversityAir quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne. Lead, arsenic, cadmium, and other toxic elements are often present in such particles. These pollutants can damage the health of people living near the mining site.
