Off the shelf reverse osmosis technology coupled with innovative design features. Multimedia, filtration, microfiltration and reverse osmosis with reject water going to evaporation ponds
Mt Weld near Laverton WA, some 400km from Kalgoorlie and 1000km from Perth
Challenge The process to extract rare earths at the Mt Weld mine requires water of a higher quality than is available from local aquifers. The water contains high levels of silica and the limited aquifer capacity required a treatment plant that could operate at high recovery levels. Because of the costs associated with operating in such a remote location, unmanned operation backed up by remote control was also a preferred option.
Solution Osmoflo offered a Build Own Operate contract along with a technology solution comprising a combination of off the shelf reverse osmosis technology coupled with innovative design features. The process includes multimedia, filtration, microfiltration and reverse osmosis with reject water going to evaporation ponds.
Result Commissioned in 2011, the 4ML/d plant is producing water for process requirements at nearly 80% recovery. Osmoflo’s proprietary PlantConnect® remote monitoring system in combination with supervisory technology enables full remote control of plant operation.Lynas Corporation Ltd is an ASX 200 listed company, with the strategy to create a reliable, fully integrated source of Rare Earths from mine through to market.
