North American Lithium Mine restart in La Corne
The Québec Lithium Mine, located in the municipality of La Corne 60 km north of Val-d’Or, ceased operations in 2014. Acquired in 2016 and renamed North American Lithium, the mining company decided to restart the plant and optimize its operations.
Client: North American Lithium
Location: La Corne, Québec
OUR EXPERTS’ SOLUTIONS
BBA was involved from the start of the project by reviewing the geological block model. Our mining engineering experts led a pre-feasibility study that identified many improvement opportunities for the open-pit mine using more selective mining. The team was then called upon to provide multidisciplinary engineering and project management services for the mine relaunch.
BBA ore processing experts recommended changes to the plant’s processing system by introducing ore sorting using photometry and a high-intensity magnetic separation step.
