Green Mining

Updated: Mar 2, 2019


The mining industry is a huge energy consumer that uses earth-moving and chemical processing techniques to extract the minerals and metals necessary for societal maintenance and growth. Green Mining is a movement to instill best management practices to reduce the environmental impacts of mining and its related activities. Canada's Green Mining Initiative was developed in 2009 to accelerate research, development and deployment of green mining technologies to reduce mining footprints, improve waste management, enhance ecosystem management and to develop more effective methods of remediation and reclamation after mine closure. Their initiative is expected to continue until 2020.


Green Mining Initiatives

In 2015, a benchmark evaluation report was conducted on Canada's Green Mining Initiative. Their projects include the improvement of technologies for Rare Earth Element (REE) and chromite mining, the improvement of automation and equipment, the development of safer access to underground mines, researching the fate and effects of metal contaminants, improving water recovery and recycling, mining wastes as resources, managing ecosystem restoration and mine closure, mine automation, the replacement of diesel power for underground equipment and tackling the energy requirements of earth moving.

Another Canadian-based corporation working on Green Mining Initiatives is the Centre for Excellence in Mining Innovation (CEMI). Their objectives include innovations to find more ore, to mine ore effectively and safely, to generate more value from mines and to reduce the impact of mining on the environment. Under their SustainMine Project, they're working on acquiring funding for the tailings remediation of a Crown-controlled site near Sudbury (ON) and developing tools for the classification of native plants for use in mine re-vegetation at the Victor Diamond Mine near Attawapiskat (ON).

What Green Mining strategies have been implemented or in development?

Green Mining is still in its infancy with many innovations on the horizon. Are these new technologies disruptive enough to revolutionize an industry that has only changed in scale and effectiveness in tens of thousands of years?
