BQE Water Kemess restart: selenium treatment and permitting insights for engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
BQE Water and Centerra Gold have begun preparations to restart the selenium treatment plant at the Kemess copper-gold project in northern British Columbia, originally built and briefly operated in 2020 to manage mine-impacted water. The plant is designed to remove selenium from contact water before discharge, using BQE’s specialised process technology to meet stringent provincial water quality limits. Restarting the facility signals advancing project development and will be central to permitting and long-term water management planning for any future underground or open pit operations.
Technical Brief
- Plant re-start is tied to development of a new copper-gold mine at Kemess.
- Facility was originally commissioned and operated briefly in 2020, so restart involves recommissioning rather than greenfield build.
- Experience from the 2020 operating period will inform optimisation of start-up, control logic and reagent management.
Our Take
Kemess adds to a relatively small subset of our 1242 Mining stories where selenium is explicitly flagged alongside copper and gold, signalling that selenium discharge limits are now a design driver rather than a secondary compliance issue for Canadian projects.
BQE Water Inc’s involvement at Kemess aligns with a cluster of items in our coverage where specialist water operators are retained on long-term service models, suggesting that mid-tier miners increasingly outsource complex selenium and metal-removal circuits instead of owning that process expertise in-house.
