Advanced Mineral Processing

Program Overview

Developing cutting-edge technologies and methodologies that enhance energy efficiency and reduce effluent associated with extraction, separation, and processing of iron ore and other minerals.

Recent Research

  • Iron concentrates and pellets from secondary Minnesota iron resources are being developed with process technology and feasibility demonstration of using alternate iron resources, like tailings and iron stockpiles, to make direct reduced iron to feed low emission Electric Arc steelmaking process. 
  • Improved total iron analysis developed that eliminates toxic reagents while delivering greater accuracy and precision.
