After the mine began operating, producing 8 million tons a yearof taconite, a low-grade iron ore, it would support 2,834 jobs inthe 12-county region of northern Wisconsin and Michigans UpperPeninsula, and generate a total economic impact of 604 million ayear, the report said. About 700 of the jobs would involve mining,paying an average 82,984 a year.

Environmental Analysis Of Mining Operations Dynamic Tools

The major potential environmental impacts associated with mining and associated mineral processing operations are related to erosion-prone landscapes, soil and water quality, and air quality. These potential impacts are recognized and addressed in current mining operations as well as in some former mining operations by reclaiming areas of physical disturbance to prevent erosion, stabilizing soils containing metals or chemicals to prevent unwanted metal releases into the environment, preventing a

Environmental Impacts Of Mining A Study Of Mining

Mining in the early days took place at a time when environmental impacts were not as well understood and, most importantly, not a matter of significant concern. As a result, historical mine sites may still have areas that are not reclaimed, remnants of facilities, and untreated water. This inherited legacy of environmental damage from mining is not indicative of the mining cycle today.

The most common treatment for acidic and metal-bearing waters is the addition of a neutralizing material, such as lime, to reduce the acidity. This active treatment process, which causes the dissolved metals to precipitate from the water, usually requires the construction of a treatment facility. The ongoing maintenance that such a plant requires makes this treatment technique very expensive.
