Veolia to deliver water treatment plant at gold mine

Kirkland Lake Gold has awarded Veolia Water Technologies a contract to design and supply a reverse osmosis plant to reduce the chloride levels in the water stream at the Fosterville gold mine in Victoria.

Fosterville, an underground operation 20km from Bendigo, delivered almost 264,000oz of gold for Kirkland Lake in 2017. The Canada-based company is planning to increase production at the mine to more than 400,000oz within three years.

The water treatment plant from Veolia will allow Kirkland Lake to continue meeting the conditions of the Fosterville operations licence in a sustainable way.

Kirkland Lake will implement the plant to treat mine water for reuse within the operation’s water circuit. Veolia will design and supply the plant to reduce chloride levels to below 500 milligrams a litre.

According to Veolia, the reverse osmosis plant will consist of multimedia and carbon filtration followed by primary reverse osmosis and reject recovery reverse osmosis.

“Leveraging our extensive experience in reverse osmosis technology for treating mine water, we are very proud to deliver this water treatment system to enable Kirkland Lake Gold to further enhance its sustainability credentials by producing a high quality treated water for reuse within the mine,” Veolia Water Technologies Australia client executive manager – projects Leno Cavarra said.

The water treatment plant has the capacity to treat 2 million litres a day and is expected to be operational in 2019.
