Environmental impact of iron ore mining - Wikipedia

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

ASSESSMENT OF ENVIRONMENTAL IMPACTS OF IRON ORE

However, mining of iron ore has copious negative impacts on the environment. It degrades natural landscapes, surface and ground water quality, flora and fauna, as well as the ambient air quality within the mining area and its environs. Iron ore tailings usually contain large amount of Silica, iron, and traces of Hg, Se, Cu, Pb, Zn, As, Mn etc.

Energy and Environmental Profile of the U.S. Mining Industry 4

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
