Clean TeQ to deliver $3.5m water treatment plant at Fosterville mine

Clean TeQ has secured a $3.5 million contract to develop a mine water treatment plant at Kirkland Lake Gold’s Fosterville operation in Victoria.

The Robert Friedland-chaired Clean TeQ will design, supply and commission a two million litre a day DeSALx facility for Fosterville.

During the mining process at Fosterville, the groundwater produced is currently stored at surface in limited capacity dams on the mine site.

Fosterville approach Clean TeQ to provide a system that will treat the mine water to match the quality of the region’s underlying aquifer.

Fosterville plans to use managed aquifer injection to return the water to its natural source, or alternatively, use the treated water from the Clean TeQ plant for further treatment and subsequent recycling and re-use of the water.

According to Clean TeQ, the Fosterville water treatment plant comprises an integrated precipitation and continuous ionic filtration process.

The precipitation process removes arsenic and antimony from the water as a co-precipitate. The water is then treated by the DeSALx process to remove hardness, sulphate and other dissolved metals.
