Bitterfeld Plant Set for Ramp-Up as AMG Expands Low-Cost Lithium Feedstock Operations and Secures Offtake with EcoPro

AMG Critical Materials On Track to Launch First German Lithium Hydroxide Refinery

AMG Critical Materials, a Dutch specialty chemicals producer, is making steady progress toward the ramp-up of its lithium hydroxide refinery in Bitterfeld, Germany. The first module, with a capacity of 20,000 metric tonnes per year, is designed to supply high-purity lithium hydroxide to Europe’s fast-growing battery manufacturing sector.

The German plant will process technical-grade lithium salts sourced from AMG's integrated Mibra Mine in Brazil, which produces lithium concentrate and co-produces tantalum, providing a critical cost advantage in spodumene processing.

Brazil's Mibra Expansion Strengthens AMG’s Vertically Integrated Lithium Strategy

In 2024, AMG completed the expansion of its Brazilian lithium operations, increasing production capacity from 90,000 tonnes to 130,000 tonnes per year. Despite selling 88,966 dry metric tonnes of concentrate—6% less than in 2023—the company achieved an average sales price of $854/dmt cif China.

Crucially, the Mibra Mine maintains a low production cost of $458/dmt, supported by tantalum byproduct credits. This low-cost feedstock enhances AMG’s competitive position as the Bitterfeld plant begins to scale production.

Offtake Agreement Secured with EcoPro as European Battery Market Grows

To ensure downstream placement, AMG signed a binding multiyear supply agreement in 2022 with South Korea’s EcoPro, one of the world's largest cathode material producers. Under this deal, AMG will supply battery-grade lithium hydroxide from its Bitterfeld refinery, reinforcing its role in the European EV battery supply chain.

The project aligns with EU ambitions to localize and secure critical raw material supplies amid growing demand for sustainable energy technologies. AMG’s fully integrated mine-to-refinery model positions it as a key player in Europe’s lithium ecosystem.
