The majority of historical iron mining activities in Wisconsin involved the removal of highgrade (directshipping) ore, which was mined in several areas throughout the state. The major remaining deposits are taconite, a lowgrade (typically 2030% iron) ore that requires processing to increase the iron content and remove impurities.
In 1955, the Reserve Mining Company began operating in Silver Bay, Minnesota. The processing plant for Reserve''s taconite mine was situated right off the shore of Lake Superior, but in the 25 years that the company was operating, the distance between the processing plant and water''s edge slowly grew.
Taconite is a low grade ore when compared to Magnetite and Hematite, and is silica rich. Historically speaking Taconite was always believed to be just a waste product of iron ore mining but after the end of the Second World War, it soon became obvious that all of the sources of high grade iron ore .
Taconite, a lowgrade siliceous iron ore composed of 20–30 percent magnetite occurring in finegrained banded iron formations. Taconite is mined primarily in the, in the Mesabi Iron Range in Minnesota and the Marquette Iron Range in Michigan.

Aug 07, 2019· In 1956, the giant Northshore Mining plant on the shores of Lake Superior was the first facility built in North America to make pellets out of taconite, a lowgrade iron ore. It used a process ...
A taconite iron ore processing facility separates and concentrates iron ore from taconite, a lowgrade iron ore, and produces taconite pellets, which are approximately 60 percent iron and about ½ inch in diameter. These pellets are then utilized, mainly, in blast furnaces making iron and steel and in the cement industry. Rule History

The trucks take the taconite directly to the processing plant, or the taconite is transported if further away. Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines.
Jan 25, 2019· In the late 1990s, miners in Minnesota''s taconite iron ore mining industry began experiencing an unusual uptick in cases of a rare and fatal cancer called mesothelioma. To date, more than 100 cases of mesothelioma have been identified in Minnesota miners.

In 1947 Pickands Mather announced that Erie would build a demonstration plant to make taconite ore into pellets — three tons of taconite to make one ton of pellets and two tons of tailings. And the plant would be massive. Erie opened in 1957. The total cost seemed astronomical — 300 million — and it would take four years.
After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota''s iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.
Dec 15, 2018· Taconite (iron ore) mining, located in northeastern Minnesota and the upper peninsula of Michigan, has been in existence since the early 1950s. It replaced the mining of more concentrated hematite ore after the latter''s depletion after the second world war.
Though taconite was identified as an ironbearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn''t until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...
