A specialized facility developed at the Noranda Technology Centre and installed at McGill University, this unit is designed for extensive research into the self-heating potential of sulfide materials. It helps determine the mechanisms and reactions involved in sulfide self-heating, which can occur in three stages (A, B, C) influenced by factors such as moisture content, degree of compaction, air humidity, and oxygen availability. Understanding these processes is crucial for mitigating hazards in mining, mineral processing, and smelting operations. The unit supports studies on the exothermic oxidation reactions of sulfide minerals, particularly those containing pyrrhotite, and the role of elemental sulfur in these reactions.
