    The environmental impact of iron ore mining, in all its phases of, from excavation to beneficiation to transportation, may include detrimental effects on air quality, water quality, and biological species. 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.
