Mining, a large industry in Minnesota, creates waste and uses substantial amounts of energy. The iron ore is recovered from taconite, which is a challenging process that produces large amounts of waste and requires
The United Taconite mine is located on Minnesota’s Mesabi Iron Range in and around the city of Eveleth, Minnesota. The taconite is mined and then transported approximately 10

The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock. The shovels place the taconite into giant dump trucks. These trucks are as big as a house and hold up to 240 tons of

Minntac began production of taconite pellets in 1967 and is the largest taconite producer in North America with an annual production of up to 15 million long tons of pellets. Lowgrade taconite iron ore of the Biwabik Iron Formation is extracted from a connected series of open pit mines stretching over an area of approximately eight miles
THE PROCESSING OF TACONITE Taconite cannot be used in a blast furnace in its natural state. This fact, combined with the fact that the crude ore contains only about 25 per cent iron, has necessitated the location of processing plants in the mining area, rather than at the steelmill centers. A huge investment of capital is required.
Mining Solutions is composed of Minnesota Ore Operations, as well as U. S. Steel’s ownership interest in one joint venture. Mining Solutions has a combined annual capability of just over 23 million tons. Our highquality taconite pellets range from standard acid pellets to highgrade flux pellets containing approximately 65% iron.
Each pocket contains a sample of taconite, including "Crude Taconite","Concentrate" and "Pellets", and a printed description of the mining process that created each sample. The reverse of the packet is printed with information about Minnesota taconite, the mining process, and the benefits that taconite mining offers the state of Minnesota. Quantity

Taconite mining has had a significant impact on the environment in Minnesota. The process of mining and processing taconite can release harmful pollutants into the air and water. As a result, the state has strict regulations to protect air and water quality. Despite these regulations, taconite mining has still had some negative
Stauber noted mining has been a dominant industry in Northern Minnesota for more than a century. “It’s about ending an industry that has employed Minnesotans and Iron Rangers for over 130 years,” he said. McCollum noted there was a carve out in the bill for taconite mining, a traditional Iron Range product.

Taconite is a hard, dense rock containing a mixture of silicates and magnetite and is abundant on the Mesabi Range. New processing methods developed in the mid20th century made taconite mining profitable. After it’s mined, the taconite is crushed into a fine powder. The magnetite is separated with magnets and agglomerated into marblesized

Mining companies argue that modern techniques can protect the environment and that engineering plans are heavily scrutinized in the permitting process before any projects are approved. But the government argued that the Boundary Waters is too special a place to risk to a process that often underestimates environmental impacts.
As PolyMet’s proposed copper mine, NorthMet, has moved forward, tribal communities and environmental advocacy groups who have long grappled with the problems caused by taconite mining are now arguing vociferously against a coppernickel project that could be even more damaging. Despite efforts by these groups, PolyMet was on the
