presents an opportunity for understanding of chal-
copyrite flotation.
This work has demonstrated the significance of multidimen-
sional consideration in deciphering the challenges associ-
ated with chalcopyrite flotation. Both galvanic interactions
and pulp chemistry variables will continue to be challenges
as we exploit low-grade ores characterized by diverse min-
eralogical assemblages with increased quantities of electro-
chemically active gangue minerals such as pyrrhotite.
ACKNOWLEDGMENTS
The authors would like to extend their heartfelt appreciation
to MITACS, in partnership with SK Godelius, Glencore,
Vale, and Magotteaux, for their significant financial con-
tribution. This support was instrumental in the successful
completion of this research. The staff members at Queen’s
University’s Robert M. Buchan Department of Mining are
acknowledged for their consistent assistance, direction, and
provision of necessary resources during the duration of this
study. The authors further extend their deepest apprecia-
tion to the anonymous reviewers who kindly volunteered
their time and skills to critically examine and provide con-
structive input on our work, adding considerably to the
refinement and advancement of the research.
