Cornish completes test site to extract lithium from geothermal waters
(Kitco News) - Cornish Lithium, the pioneering mineral exploration and development company headquartered in Cornwall, announced Monday that it has successfully completed the construction of its United Downs Geothermal Water Test Site in Cornwall, UK, and installed its first demonstration plant to trial environmentally-responsible Direct Lithium Extraction ("DLE") process technologies.
The company said that the facility designed to establish which DLE technologies are most suited to low-carbon extraction of lithium from Cornish geothermal waters.
The first technology, Geolith, utilizes microfiber-based materials with selective absorption properties, which will act as a "filter" to selectively capture lithium or unwanted contaminants. The Geolith demonstration plant is expected to be in operation for three weeks from Wednesday 9 June 2021.
The second technology, Precision Periodic's proprietary Nano Beads™ filtration media, is designed to extract and concentrate lithium ions without the need for pretreatment, heat, or pressure. The process is expected to generate zero waste and the geothermal waters can be returned to the source - once just the lithium ions have been extracted - or filtered with additional Nano Beads that will clean the geothermal waters of other elements that could potentially produce water for other applications such as farming.
Cornish has also announced that the company made a significant progress towards defining its maiden Resource estimate at its lithium in hard rock Trelavour Project, which is expected in autumn 2021.
Jeremy Wrathall, CEO and Founder of Cornish Lithium, said, "Our lithium in geothermal waters test site at United Downs provides us with an opportunity to demonstrate what modern, low-carbon mineral extraction looks like, and the results will inform the development of the larger pilot plant that we intend to construct by the end of March next year."
Cornish Lithium is an innovative, eco-technology company focused on mineral exploration and development for the environmentally sustainable extraction of lithium in the historic mining district of Cornwall, UK.
