Spruceglen arrived in Duluth 03/27/21

Spruceglen horn:
Spruceglen arrived in Duluth early this morning to load iron ore pellets.


  1. What's the difference between taconite and iron ore pellets?

  2. 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.
