Jaylon Environmental Systems will supply and install evaporation pond liners for Kalium Lakes’ Beyondie sulphate of potash (SOP) project in Western Australia after winning a $15 million contract.
The sheet plastic specialist, known for its suite of industrial products such as geomembrane landfill and dam liners, rainwear and tarpaulins, will provide one-millimetre thick HDPE covering over a roughly 400-hectare evaporation area at the site. 500microns Hdpe Geomembrane Liner
Jaylon has a history with Beyondie, having supplied liners to cover 10-hectare ponds during the project’s pilot stage in 2017.
Kalium Lakes chief development officer Rudolph van Niekerk said the company’s plan for a lined pond design would allow for harvesting “months, if not years” ahead of other alternatives.
“The use of Jaylon during the pilot scale trials continued to validate Kalium Lakes’ de-risking strategy, where we work collaboratively to develop bespoke, low cost and fit for purpose solutions for the (Beyondie SOP project),” he said.
“The use of an evaporation pond liner has been a much debated topic. For Kalium Lakes, the cost of the supply and installation of the liner represents less than seven per cent of the project’s total capital cost but results in an increased SOP process recovery of more than 15 per cent.”
Kalium Lakes’ initial $1 million order of the liners for this latest contract was placed in May 2019.
The Beyondie project has now received all necessary approvals for construction, boasting an average recovery of 12.4 kilograms of SOP per cubic metre over an initial 30-year mine life for 19.6 million tonnes of drainable mineral resource.
