Evolving metal extraction processes
Yet, for more than a century, most extraction processes rely on techniques and pathways that would be familiar to metallurgists from generations ago.
Key points
- Processes have become larger and control systems smarter, but the fundamental science behind separating metals from ores has changed less than many realize.
- EvoMaterials is based on the idea that some metallurgical processes may benefit from entirely different chemical pathways.
- According to Antoine Allanore, professor of metallurgy at the Massachusetts Institute of Technology (MIT) this coincides with many Western economies having reduced their domestic processing capacity for the very metals those industries depend on.
The new method creates a different chemical environment that enables more efficient extraction with fewer losses and fewer unwanted by-products, recovering critical materials from resources considered waste.
They could recover valuable metals from lower grade resources and industrial side streams while fundamentally altering how separation processes are performed.

- Chromium-based materials play a critical role in aerospace systems, power generation, corrosion-resistant infrastructure and defense technologies, where materials must perform under demanding conditions.
- Since then, Outokumpu has evolved the technology through extensive research and development, combining new process chemistries with proprietary metallurgical expertise, supported in part by a non-exclusive patent license agreement from MIT.
- new proprietary technology Source: Outokumpu Development of the technology began in the United States in 2021 for chromite from Outokumpu’s Kemi mine in Finland, the only chrome mine in the European Union and one of the few such operations across the Western world.
- Innovation happens at the boundaries EvoMaterials sits at the intersection of several scientific disciplines, a combination that strongly resonates with Stinn, who completed his PhD in Materials Science and Engineering at MIT, where his research focused on low-carbon metals processing and….
- The metals industry has experienced transformational moments before: the Bessemer process, flash smelting, electric arc furnaces, and modern continuous casting all changed what was possible.
