COBRE LAS CRUCES SA

Their core work

Cobre Las Cruces is a Spanish copper mining company operating one of Europe's few active open-pit copper mines near Seville. In H2020, they contribute real mining site access, operational expertise, and industrial-scale test environments for metallurgical processing research — from bioleaching and hydrometallurgy to critical raw materials recovery from mining waste. Their participation bridges the gap between laboratory-scale mineral processing research and actual mine-site validation, making them a valuable industrial partner for resource recovery and circular mining projects.

What they specialise in

How they've shifted over time

Early H2020 work (2015–2019) focused on primary ore extraction — processing polymetallic and low-grade ores through advanced hydrometallurgy and bioleaching, with Cobre Las Cruces leading the flagship INTMET project. From 2018 onward, their focus shifted decisively toward secondary resources and waste valorization: recovering critical raw materials from mining waste, using techniques like nanofibrous composites and magnetic separation alongside established bioleaching. This mirrors the EU's broader strategic pivot from primary extraction toward circular resource recovery.

Moving from primary mining expertise toward circular economy and CRM recovery — positioning themselves as an industrial partner for Europe's raw materials sovereignty agenda.

How they like to work

Cobre Las Cruces primarily joins as a participant (4 of 5 projects) but demonstrated coordination capability with INTMET, their largest project at EUR 2.7M. With 95 unique partners across 25 countries, they operate in large research consortia rather than small focused teams. Their role is that of an industrial host and end-user validator — bringing real mine-site conditions to research projects rather than leading the science.

Broad European network spanning 95 partners across 25 countries, reflecting participation in large multi-partner consortia focused on raw materials and mining research. Their geographic reach covers most of the EU research landscape rather than concentrating on any single region.

What sets them apart

As one of very few active copper mine operators participating in H2020, Cobre Las Cruces offers something most research consortia struggle to find: a real, operational mine site in the EU for testing and validating extraction technologies at scale. Their progression from primary ore processing to waste-stream CRM recovery means they understand both conventional and circular mining. For any consortium needing an industrial mining partner in Southern Europe with hands-on bioleaching and hydrometallurgy experience, they are a rare find.

Highlights from their portfolio

• INTMET
  Their only coordinated project and by far the largest (EUR 2.7M) — an integrated metallurgical system for complex, polymetallic, and low-grade ores.
• RAWMINA
  Most recent and second-largest project (EUR 1.6M), representing their strategic shift toward CRM recovery from mining waste in a circular economy framework.
• NEMO
  Near-zero-waste recycling concept turning sulphidic mining waste into critical metals, REE, and construction materials — bridging mining and materials science.
