RSE can confirm that the Direct Lithium Extraction (DLE) Pilot Plant for GeoCubed at Cornish Lithium’s Geothermal Waters Test Facility at United Downs was commissioned and delivered at the end of March 2022, according to time and on budget. The project was delivered in collaboration with RSE company Sheers.
The Direct Lithium Extraction Pilot Plant has been designed to process Cornish geothermal waters using DLE technologies and is the first time that a DLE system has become operational in the UK. The £4 million Pilot Plant is being supported by the Cornwall and Isles of Scilly Local Enterprise Partnership (LEP), with a £2.9 million grant from the UK Government’s Getting Building Fund.
Initially, the Pilot Plant will test the GeoLith Li-Capt® DLE technology and process the 140 metres of deep geothermal water successfully obtained during Geothermal Engineering Limited’s (GEL) testing at its own United Downs site last year. This is expected to confirm that lithium can be produced in Cornwall from geothermal waters, and the Pilot Plant is expected to provide sufficient information to enable the design of a commercial lithium plant in the county.
