Recovery and repurposing of thermal resources in the mining and mineral processing industry

McLean Shannon H., Chenier Jeffrey, Muinonen Sari, Laamanen Corey A., Scott John A.

Journal of Sustainable Mining

2020

Vol. 19, iss. 2

115--125

The consumption of energy contributes significantly to the overall cost of operations and the environmental impact of the mining and mineral processing industry. However, despite a few notable exceptions, most of the resulting waste heat produced is dissipated, without recovery, into the environment. There is also a lot of stored heat in mine water which can be tapped into long after a mine has closed. There is, therefore, significant opportunity to improve the industry's sustainability through increasing the amount of waste heat recovered and repurposed.
