Iberian Pyrite Belt: Braga → Riotinto mines → Braga
The post-conference field trip will conclude the IMWA 2025 experience with an in-depth exploration of the Iberian Pyrite Belt, one of the most relevant mining regions in Europe. With a history of mining that dates back to pre-Roman times, this region is home to some of the oldest and largest mines on Earth. This excursion includes visits to Aljustrel, São Domingos, and Riotinto mines.

On the way back from the Riotinto mines to Braga, we stay overnight in the interior of Portugal to visit the Urgeiriça uranium mine, once one of Portugal’s biggest environmental problems. Participants will emerge from the field trip with a comprehensive understanding of the complexities involved in mine water management and the innovative solutions being implemented to address these challenges.
- Witness the striking mineralogical and ecological features shaped by centuries of extreme acid mine drainage while appreciating the environmental rehabilitation efforts.
- Witness one of the largest environmental monitoring and rehabilitation projects, which includes the treatment of effluents and the recovery of the waste dumps.
- Explore the mining landscapes, visit historic galleries, and discover museums that preserve the rich mining legacy.
The trip will be enriched with stops at emblematic sites of Portugal’s history, culture and tradition. Highlights include the small town of Óbidos on the way to Aljustrel and the town of Évora on the way back to Urgeiriça.
