Processed battery minerals and battery recycling

Complete process solutions for dewatering, purifying, and drying of cathode and anode active materials as well as solutions for battery recycling and black mass recovery.

Because of the boom in the battery industry, demand for lithium, cobalt, graphite and silicon is on an all-time high. While each manufacturer will have its own process and often its own recipe, there are typically several steps involved in the manufacture of anodes and cathodes. With decades of process expertise, ANDRITZ offers solutions that can increase capacity and reduce production costs for a range of battery minerals. And with shredding, dewatering and drying solutions for hydrometallurgical recycling ANDRITZ helps to reduce your OPEX and to protect the environment as well.

Process know-how and a broad portfolio

High product throughput is, of course, critical to reliable and cost-efficient production of all types of battery minerals. This is why many larger processors of graphite, magnesium and cobalt have long depended on us for the most efficient mechanical dewatering and purification solutions.

precursor fine or middle particle filtration,
precursor fine or middle particle drying,
calcination filtration or pre-calcination cooling?

We’ve got you covered!

Our portfolio covers a variety of thickening and dewatering technologies, ranging from filter presses and horizontal vacuum belt filters to vacuum and pressure drum filters, peeler and pusher centrifuges, to heavy-duty belt presses for dewatering, as well as helix, paddle and plate dryers for the drying step. This diversity means that we are able to configure a solution that is tailored to meet your specific needs.

Where we support your CAM and pCAM process

Cathode Active Materials (CAM) are typically composed of metal oxides. The most common cathode materials used in lithium-ion batteries include:

Lithium Cobalt Oxide (LiCoO
Lithium Manganese Oxide (LiMn₂O₄)
Lithium Iron Phosphate (LiFePO₄ or LFP
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO₂ or NMC):

Each of these materials offers varying levels of energy density, thermal stability, and cost-effectiveness. ANDRITZ provides filtration and drying solutions to enable the best process results with optimized recovery rates and minimum environmental impact.

Exploring new processes for battery recycling

Thanks to process expertise, extensive experience, and proven systems for most process steps, we can aid you in the development or the finetuning of your recycling process for Li-Ion or other batteries. Shredders break down the batteries and separate the black mass, which is then filtered, washed and dried to recover valuable raw material, such as lithium, cobalt, or graphite. Recycling these raw materials instead of simply dumping old batteries on landfill sites benefits both your OPEX and our environment.
