Metso is the Finnish mining- and aggregates-technology group that supplies and services much of the processing equipment at Portugal's largest mines. Formed in 2020 by the merger of Metso and Outotec — and renamed simply Metso in 2023 — it is headquartered in Espoo, Finland and employs roughly 17,000 people worldwide.
Metso's Portuguese footprint runs through the Iberian Pyrite Belt, where it is the key processing-technology partner to the country's two largest base-metal mines. At Lundin/Somincor's Neves-Corvo copper-and-zinc operation it has supplied core equipment including a C120 jaw crusher, flotation cells and VPA filter presses for thickened-slurry filtering — the heart of the concentrator flowsheet.
In 2023 Metso secured a major order from Almina – Minas do Alentejo to supply a complete "grinding island" for the upgraded copper-and-zinc concentrator at the Aljustrel mine, deepening a long-standing relationship. Metso reports a presence at nearly every Iberian mine, ranging from individual equipment lines to complete plant solutions, supported from its Iberian sales and service organisation.
Metso is a textbook case of Nordic industrial-technology depth inside Portugal's mining renaissance. As Portugal's base-metal output expands to feed Europe's energy-transition demand for copper and zinc, the Finnish group's crushers, mills, flotation cells and filter presses are embedded in the country's most strategic export industry — a quiet but structural strand of the Nordic-Portuguese corridor.
In late 2023 Metso booked the Almina/Aljustrel concentrator-upgrade order and has continued to expand its Iberian service footprint, positioning itself for further work as Portuguese and Spanish miners modernise processing capacity through 2025–2026.
