Metso–GTK Mintec concentrator deal: pilot plant design insights for process engineers

30 Second Briefing
Metso has signed an agreement with the Geological Survey of Finland (GTK) to engineer and deliver concentrator process technology for GTK Mintec’s new minerals processing and circular economy pilot plant in Outokumpu. The delivery will cover a full concentrator flowsheet, enabling pilot-scale testing of ore beneficiation and secondary raw materials, supporting clients with process design, upscaling and feasibility work. For engineers, the facility offers a Nordic test centre to de-risk comminution, separation and recycling circuits before commercial deployment.
Technical Brief
- Agreement scope explicitly covers both engineering design and physical delivery of Metso concentrator process equipment.
- GTK Mintec’s Outokumpu facility is configured for both primary ore and circular-economy secondary materials.
- Pilot plant expansion is framed as a major increase in GTK’s contract research and testwork capacity.
- Metso’s package is described as “process technology”, implying integrated OEM control and instrumentation with the plant.
- GTK positions the plant as a service platform for the wider mining and minerals industry, not just internal R&D.
Our Take
Metso’s work with GTK Mintec in Finland sits alongside a run of recent large-scale process plant awards in our database (Troilus, New Simberi, Yitirrti, Yenipazar), signalling that its concentrator and flotation technology is being locked in early across both R&D/pilot and full-scale project pipelines.
Because GTK Mintec’s new pilot plant in Outokumpu is framed around minerals processing and circular‑economy materials, it is likely to become a low‑risk test bed for the kind of Metso flowsheets now being deployed at copper‑gold projects like Troilus, helping de‑risk process choices before commercial roll‑out.
