Dr. Brian Hart

Research Scientist,
Adjunct Professor, Dept. of Earth Sciences

Dr. Hart is currently the group leader for the mineral chemistry and mineral processing group at SSW. He conducts contract research that is industry sponsored as well as independent research using Surface Science Western’s unique combination of instruments. Current research emphasis involves factors affecting value added mineral recovery. Active projects include a variety of programs directed towards refining the capabilities of the ToF-SIMS for mineral processing and extractive technology-related applications.



Research Interests Include:

Mineral surface chemistry by ToF-SIMS and XPS:

  • Element transfer between mineral phases
  • Au extraction technology
  • Oxidation effected mineral recovery
  • Collector attachment efficiency

A variety of topics in the field of geochemistry and soil chemistry with emphasis on environmental aspects of waste utilization and soil remediation including:

  • Trace elements in waste materials: municipal and rural biosolids, solid combustion products
  • Trace metal aqueous geochemistry with emphasis on the source pollutants and their fate
  • Waste materials and soil remediation technology
