FINLAND —Betolar and the Geological Survey of Finland (GTK) have established a five-year research framework to evaluate methods for recovering metals and other usable materials from mine tailings and industrial by-products, including slags generated by steelmaking. The cooperation will bring laboratory analysis, mineral processing and high-temperature smelting tests together at GTK Mintec in Outokumpu, Finland, with Betolar planning to locate its proof-of-concept furnace alongside the facility.
The technical arrangement is intended to help mining and metals companies assess the recovery potential of waste streams before committing capital to full-scale processing. GTK Mintec operates mineral-processing laboratories and an industrial-scale pilot plant, while Betolar’s furnace will add pyrometallurgical testing through high-temperature treatment. GTK’s analytical capabilities will support evaluation of processed materials, while the furnace will allow the partners to investigate how metals can be extracted and remaining fractions potentially reused.
The initiative addresses a resource challenge for European industry: significant quantities of potentially valuable metals remain in residues accumulated through historical mining and industrial production. Recovering materials from existing tailings and slags could provide an additional source of raw materials, reduce the volume of waste requiring management and support more circular approaches to mineral and metal production. The practical viability will depend on the composition of individual waste streams, recovery performance, processing costs and the market value of recovered materials.
For mining operators, steelmakers and downstream manufacturers, the collaboration could provide a route to test site-specific materials before making larger investment decisions. Pilot-scale trials can help establish technical feasibility and generate evidence needed to evaluate commercial recovery projects. The work may also be relevant to supply-chain strategies for critical raw materials, although the agreement does not guarantee commercial production or specify recoverable volumes, project investment or revenue targets.
Betolar is a materials technology company focused on developing solutions that use industrial side streams and support resource-efficient material applications. GTK is Finland’s national geological survey, providing geological expertise, research and mineral-processing facilities. Under the memorandum, the parties may undertake joint research and development projects and, where mutually agreed, apply for research funding. The arrangement is non-binding, leaves both organisations free to work with other partners, and requires separate agreements for individual projects. Its five-year term establishes a framework for testing and development rather than a commitment to a specific commercial deployment.
