Zinnwald Lithium and Metso advance testwork program

Zinnwald Lithium Plc (“Zinnwald Lithium”) and Metso continue to make excellent progress developing the beneficiation plant concept for the integrated Zinnwald Lithium Project located near Dresden/Germany. This project, which is situated in the heart of the European chemical and automotive industries, is designed to supply battery-grade lithium hydroxide (LiOH) to the battery sector. Anton du Plessis, CEO of Zinnwald Lithium, comments: “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.”

Metso was engaged to assist Zinnwald Lithium with its Definitive Feasibility Study in early 2022. The two companies have since been working on developing a successful beneficiation process flowsheet based on a complete mineralogical study, batch, and locked cycle tests. The design basis of the tests considers the mixture of two distinctive lithium ore types, Alibite Granite and Quartz Mica Greisen, potentially expanding the resource base considerably. “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,” Anton du Plessis added.
