Clean TeQ Holdings Limited (ASX: CLQ), has entered into a landmark agreement with Fosterville Gold Mine Pty Ltd to design, supply and commission a two million litre-per-day Clean TeQ DeSALx mine water treatment plant in Victoria.
The company said the award of the $3.5 million contract follows a period of extensive due diligence and testwork conducted by Fosterville to validate the efficacy of Clean TeQ’s DeSALx system for the treatment of mining process waters. The value of the contract is $3.5 million and serves as a significant milestone for the Clean TeQ Water division.
Clean TeQ Co-Chairmen Robert Friedland and Jiang Zhaobai said the Fosterville water treatment plant is an important reference project for Clean TeQ’s DeSALx technology, which is expected to add significant momentum to the growing pipeline of Clean TeQ Water projects.
Fosterville operates the Fosterville Gold Mine near Bendigo. During the mining process, groundwater is produced which is currently stored at surface in limited capacity dams on the mine site.
To create a more sustainable water management strategy, Fosterville approached Clean TeQ to provide a system that will treat the mine water to match the quality of the region’s underlying aquifer.
Fosterville can then use managed aquifer injection (MAI) 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. The DeSALx Technology.
The Fosterville water treatment plant comprises an integrated precipitation and continuous ionic filtration process (DeSALx).

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. DeSALx technology is ideal for complex mine wastewater treatment. The DeSALx process can be used as a standalone or as a pre-treatment for membrane based water treatment systems.
As the DeSALx by-product is gypsum-based, it is compatible with Fosterville’s currentlt established lime treatment facility and provides a zero-brine water treatment solution. Design of the Fosterville water treatment plant is already underway, with equipment supply, installation and commissioning all scheduled for 2018.
Clean TeQ Water is actively engaged with several mining companies globally in testing our unique continuous ion exchange systems for the treatment of process water treatment for recycling or environmental discharge.
