Collaborative Testing Program between Zinnwald Lithium and Metso


Zinnwald Lithium Plc and Metso make great progress in designing the beneficiation plant for the integrated Zinnwald Lithium Project in Dresden, Germany, to serve the European battery industry.

Anton du Plessis, CEO of Zinnwald Lithium, says, “Achieving resilience and sustainability for the electric vehicle battery supply chain is essential, including in Europe where over 30 new gigafactories are planned by 2030. Our vision is to build a world-leading integrated lithium hydroxide operation to support this supply chain, adhering to the highest environmental standards. We are therefore delighted with the progress being made with Metso as we look to design the best possible particle sorting, otherwise known as the beneficiation process, for the plant.”

Metso collaborated with Zinnwald Lithium in early 2022 for the Definitive Feasibility Study. They have been jointly developing a beneficiation process based on mineralogical analysis and testing, enhancing resource potential.

“After the completion of the beneficiation pilot, we will start refinement of the calcination and hydrometallurgical flowsheet. We have partnered with Metso to develop and deliver this project as a “one-stop shop” to reduce the need for engagement with multiple suppliers and to maximize in-house expertise in the design of the plant from Run-of-Mine to the battery-grade final product,” Mr. du Plessis further added.

Mikko Rantaharju, Vice President of Hydrometallurgy at Metso said, “Metso is delighted to support Zinnwald Lithium with the development of this ambitious project. Development and supply of state-of-the-art, sustainable processes and equipment for the critical minerals required for the electric vehicle supply chain is an essential part of our minerals processing expertise.”

Metso provides sustainable technology and equipment for manufacturing battery materials, assisting the energy transition with its distinct Planet Positive approach.

Metso provides end-to-end solutions for the lithium, nickel, and cobalt production processes, from mining to battery materials and recycling.
