HOUSTON, TEXAS (Editors at Energy Analytics Institute, 20.Mar.2025) — Rock Tech Lithium Inc. entered a technology partnership with GEA Group AG, 1 of the world’s largest system suppliers for advanced process technology, to deliver key equipment for its lithium converter in Guben, Germany.
As part of the agreement, GEA will supply crystallization and zero-liquid discharge technology, ensuring the highest standards in battery-grade lithium hydroxide monohydrate (LHM) production, Rock Tech announced on 20 Mar. 2025 in an official statement.
Following 2 1/2 years of an intensive selection process followed by technical specifications and negotiations, Rock Tech has successfully completed test works with GEA to procure crystallizers essential to produce 24,000 tons per year (t/y) of battery-grade LHM. This equipment contract is a significant step to establish an automated and continuously operating lithium converter in Europe.
The cooperation with GEA ensures that Rock Tech benefits from the company’s extensive process knowledge, market expertise, and technical capabilities. In the past few years GEA has contributed to key lithium crystallization projects globally. Among others, GEA supplied technology for a lithium hydroxide plant in Argentina (25,000 t/y), 2 process plants for lithium hydroxide production in South Korea, a facility producing 20,000 t/y in Europe and crystallization and drying technology for an Australian lithium plant.
Additionally, GEA supplied several lithium hydroxide production lines focusing on solid-liquid separation technologies for a leading North American Lithium producer. These projects underscore GEA’s expertise in high-purity lithium hydroxide production for battery applications. With terms on scope, services, warranties, and timelines now finalized, the formal contract signing is the next step, subject to the project’s final investment decision (FID).
