Blind River Refinery

Cameco's Blind River Refinery opened in 1983. Today, it's the world's largest commercial uranium refinery.

Uranium ore concentrates are shipped here from mines around the world, including those in Canada, Australia and the United States. The facility includes a processing plant, water treatment plant, power plant, and analytical labs.

In the processing plant, we refine uranium concentrates to produce a purified product called uranium trioxide (UO₃) which is then shipped to our Port Hope Conversion Facility for further processing.
