Which Evonik product has been selected for the pilot phase II of Neptune Energy’s Altmark lithium extraction project, and what is its brand name?

Evonik’s adsorbent, traded under the Liocel brand, has been selected as the first material to be evaluated in the DLE pilot plant developed by Fraunhofer IEG for pilot phase II of Neptune Energy’s Altmark lithium extraction (ALE) project.

What technology is Neptune Energy using to extract lithium in the Altmark project, and why was adsorption technology chosen for pilot phase II?

Neptune Energy is using direct lithium extraction (DLE) technology to extract lithium from geothermal brine. Following evaluations of several commercially available DLE technologies—including ion-exchange and adsorption processes—during pilot phase I under Altmark-specific conditions, adsorption technology was selected for further investigation in pilot phase II.
