TACONITE IRON MINING IN WISCONSIN A REVIEW

The majority of historical iron mining activities in Wisconsin involved the removal of high-grade (direct-shipping) ore, which was mined in several areas throughout the state. The major remaining deposits are taconite, a low-grade (typically 20-30% iron) ore that requires processing to increase the iron content and remove impurities.

Taconite Mining and Processing Industry Profile

Taconite, the principal iron ore mined in the United States, has a low (20 percent to 30 percent) iron (Fe) content and is found in hard, fine-grained, banded iron formations. The main taconite iron ore deposits are located near Lake Superior in Minnesota (Mesabi Iron Range) and Michigan (Marquette Iron Range). The taconite mining operations in

Gogebic Taconite Mine Project Encyclopedia of Wisconsin

Taconite is the largest iron ore that is economically viable to mine in the Penokee-Gogebic Range. This ore formerly was not economically viable based on its lower composition of iron compared to magnetite. However, mining practices and technology over the last few decades around the Lake Superior region have made taconite mining economically
