Battery minerals

High-purity lithium, graphite, and cobalt with lower energy costs

As battery production continues to rise, so does the demand for high-purity lithium carbonate, graphite, and cobalt. Our turnkey process solutions for dewatering, purifying, and drying make it possible to meet this challenge with high efficiency and product quality.

Five decades of expertise in lithium

The first ANDRITZ SEPARATION pusher centrifuge for lithium carbonate, installed more than 50 years ago, remains in operation today. This represents our commitment to supplying the world’s largest lithium producers with robust separation technologies that withstand a long lifetime of continuous use.

Our technologies, ranging from decanters and centrifuges to thickeners and dryers, cover the entire process from dewatering to purification and drying. In the case of lithium hydroxide, a lowtemperature, low-energy drying solution is often required in order to avoid product decomposition. ANDRITZ SEPARATION makes this possible with a range of drying technologies based on closed gas loop operation, which better preserve product quality while conserving energy.

High-volume graphite and cobalt

High product throughput is, of course, critical to reliable and costefficient production of all types of battery mineral production. This is why many larger processors of graphite and cobalt have long depended on us for the most efficient mechanical dewatering and purification solutions. Our high-capacity filter presses and thickeners ensure low operating and energy costs for some of the highest volume operations worldwide. Put together, our complete process solutions for battery minerals help leading producers to continuously expand and compete in this fast-growing global market.
