Taconite Mining in Silver Bay: A Tale of Extraction and Accumulation
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. A vast delta had been created by the accumulation of the fine waste-rock that Reserve was discharging into Lake Superior.

Taconite is an iron-bearing and silica-rich rock with an iron content of 15–30% and a silica content of 45–50%. The mining and processing of the taconite ores includes four main steps—mining, crushing, concentrating, and pelletizing—that increase the iron content to as high as 65% in the final product ( Hubbell et al., 2001; US EPA, 2012 ).
