Metso Elevates Lithium Hydroxide Technology to Meet Soaring Battery-Grade Demand

In response to the escalating demand for battery-grade lithium essential for the ongoing energy transition, Metso has undertaken a comprehensive evaluation of its lithium hydroxide technology and service offerings. This strategic review reflects the company's commitment to addressing the surging need for high-quality lithium required in the manufacturing of lithium-ion batteries, particularly for electric vehicles.

An integral aspect of this exhaustive review is the validation of Metso's proprietary sulphate-free alkaline pressure leach process as a Planet Positive technology for battery-grade lithium production. This innovation underscores Metso's dedication to sustainable practices in lithium refining, aligning with the imperative goals of the energy transition.

Metso's hydrometallurgical alkaline leach process emerges as a simple and secure method for refining spodumene concentrate into battery-grade lithium products, including lithium hydroxide monohydrate and lithium carbonate. This innovative refining process yields high-purity lithium salts and hydrates crucial for the cathodes of lithium-ion batteries powering electric vehicles.

Metso's commitment to sustainable alkaline leaching technologies spans two decades, focusing on hard rock lithium sources. The current offering includes proprietary technologies tailored for refining lithium from spodumene mineral concentrates. Continuous research and development, along with pilot projects, are underway to explore the processing of lithium-bearing pegmatite hard rocks like petalite, zinnwaldite, and lepidolite. Additionally, Metso has established processes for extracting lithium from brines, showcasing its versatile approach to lithium sourcing.

Marika Tiihonen, Technology Manager for Lithium at Metso, emphasizes the critical role lithium-ion batteries play in mitigating global warming, particularly in electric vehicles and renewable energy storage systems. The surge in lithium projects, driven by these imperatives and the regionalization of critical mineral sourcing, positions Metso as a reliable partner supporting various battery minerals projects in different phases, from study and piloting to engineering and delivery.

Metso's commitment goes beyond technology development, extending to providing end-to-end solutions for lithium hydroxide and battery minerals projects. From mining to battery materials and even the recycling of black mass, Metso positions itself as a robust and dependable partner in the evolving landscape of sustainable energy solutions.

Metso's strategic evaluation of lithium hydroxide technology and services not only meets the growing demand for battery-grade lithium but also aligns with global sustainability goals. The validation of their sulphate-free alkaline pressure leach process as a Planet Positive technology underscores Metso's dedication to eco-friendly lithium production. As the company continues to support and drive lithium projects across various phases, it stands as a beacon in the pursuit of sustainable and responsible practices in the energy and battery minerals sector.
