NRRI Coleraine

Situated near the taconite iron ore mines on the Minnesota Iron Range, NRRI’s Coleraine lab is a world renowned center for iron ore-related research. The lab was established in 1965 by U.S. Steel to assist with mining and processing research. It was transferred to NRRI in 1986. Since then, it has expanded its research portfolio into environmental and biomass energy fields, as well as broader mineral processing activities to include non-ferrous metals and industrial minerals. NRRI's Coleraine Lab employs 9 engineers and 15 Lab Technicians.
