Iron Ore And Taconite Mine Reclamation And Revegetation

Iron mining operations began on the Mesabi Range in 1884 where strip mining was the most common method used to gain access to the ore. The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today. As the rich ore was depleted taconite mining operations began.

What is taconite ore used for?

Taconite is a low-grade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20- 30% compared to 50 – 60 % iron content in red ore.
