Hubbell U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Innovative Strategies and Economics Group (MD-15) Research Triangle Park, NC 27711 EPA Contract Number 68-D-99-024 RTI Project Number 7647.002.142 September 2001
Taconite mining and processing causes widespread regional impacts The track record of regional taconite mining instructs Wisconsin on what should be expected if a mine is permitted here. Air and water quality in northern Wisconsin would be harmed by mining waste
Northern Minnesota's Iron Range was a hub for iron ore mining from the end of the 19th century through 1984. The region still exports taconite, a low-grade form of the ore, and some high-grade ore, but no longer approaches the economic heights of the Iron Range's peak years.
Aug 22, 2018· While underground mining, which allows coal companies to extract deeper deposits of coal, is viewed as less destructive than strip mining, the effects of mining widespread damage to the environment.

Environmental review Environmental Assessment Worksheets and/or Environmental Impact Statements are required for new mining proposals and are often required for expansions of existing operations as stated in Minnesota Rules, part 4410.4300, subparts 11-12 & Minnesota Rules, part 4410.4400, subparts 8-9.
Environmental Study of Airborne Particulates. The goal of the proposed environmental study of airborne particulates is to evaluate the effect of past and present emissions from taconite mining on community air quality across the Mesabi Iron Range. This approach combines:
Jan 20, 2012· • As evidenced by taconite mining in MN and MI, there will be environmental impacts if a mine is constructed in the Penokee Range. At best, the landscape will be permanently altered. At worst, a variety of environmental damage and human health risks would result. Where a Penokee mine would fall along that spectrum is currently unknown.
On October 30, 2003 the Environmental Protection Agency issued a final rule which includes technology-based National Emission Standards for Hazardous Air Pollutants (NESHAP) to reduce emissions of hazardous air pollutants (HAP) from taconite iron ore processing facilities.
Oct 17, 2011· Chemically speaking, it is not difficult to distinguish the environmental impacts of mining iron-bearing oxide ores, like taconite, from those of mining sulfide ores for copper, nickel, platinum ...
Amid the spread of the new coronavirus and the likelihood of a global recession, mining companies on the Iron Range continue to staff the taconite mines and iron ore pellet plants at near-full levels.
Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material. Unlike gold mining, which often uses potentially toxic chemicals such as mercury and cyanide, gemstone mining does not depend on chemicals for extraction of the rough material.

Embedded in the layers of the delta is the history of Silver Bay's mining conflict: the struggle of a torn community, the legal battle, and the invisible health hazards that came with Reserve's pollution. The long-term impact of the taconite tailings is still debated, but the presence of the delta is not.
Taconite Dreams is a great example of how, when undertaken intelligently, local historical studies can have global reach. Jeffrey T. Manuel provides a mirror for communities across the world, from the mining regions of South Africa to the oil fields of North Dakota, through which they can assess the opportunities and threats contained in economic development strategies that rely on extractive ...
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...
