Mineral processing has a long tradition of student training and excellence in research at McGill University. There are three principal investigators, Profs. P. Radziszewski, Andre Laplante and James Finch (Industry Professor of Mineral Processing). Currently there are 3 senior research associates, 4 Post Doctoral Fellows, and 15 graduate students. The areas of research range from wear in comminution to gravity concentration of gold and chemical and physical aspects of flotation. Last year the group issued some 30 scientific papers and industrial reports. Professor Finch was elected to the Academy of Science of the Royal Society of Canada in November 2002.

The facilities include traditional mineral processing units in two dedicated laboratories as well as specialized units (e.g., Bond ball and rod mills, flotation columns, sensors for gas rate and bubble size in flotation cells) and state of the art analytical instrumentation. The latter includes: infrared, Uv/Vis, scanning electron microscopes (including variable pressure and field emission) and, through association with McGill's Physics and Chemistry Departments and the University of Montreal, XPS, ToF-SIMS, chromatography and Mossbauer spectroscopy.

The group is funded through a combination of initiatives involving the Natural Sciences and Engineering Research Council of Canada and industrial sponsors, notably, AMIRA International, Camiro, Inco, Teck Cominco, Falconbridge, Noranda, Corem and SGS Lakefield Research.
