Mine Water Treatment Plant: BGM

McCue performed the detailed design, supply, and construction of a mine water treatment plant for the Barkerville Gold Mines Ltd.’s Bonanza Ledge site, located in Wells, BC, Canada. The system design was based on coagulation, hydroxide precipitation, flocculation, settling and filtration to achieve removal of suspended solids and dissolved metals at flow rates up to 800 GPM.

The system was installed in modified shipping containers to allow for modularity and to minimize on-site installation requirements. The Barkerville Gold Mine (“BGM”)’s project was performed on an accelerated timeline, with contract award and detailed design beginning in October 2019 and system installation in March 2020. McCue commissioned the plant in September 2020.
