Optimizing Metals Removal

AREVA Resources Canada, Inc. operates uranium mining and milling facilities at McClean Lake in Northern Saskatchewan and is designing additional open pit mining capacity for uranium-rich ore at the Midwest Uranium Mine Project site about 800 km north of Saskatoon, Saskatchewan.

A multi-stage water treatment system with both physical-chemical and reverse osmosis (RO) membrane treatment has been selected to treat the combined influent groundwater and mine pit water to very strict effluent and residual waste volume requirements.
