Environmental Remediation of the Murçós Mining Area


The former mining area of Murçós is located in the civil parish of Murçós, municipality of Macedo de Cavaleiros and district of Bragança, around 1.5 km southwest of the town of Murçós and 2.7 km southeast of the village of Agrochão. The mining area occupies around 30 hectares and access to it is effected via a dirt track from the EM535-1, the road connecting Ferreira to Murçós.

A concession for this mine was granted in 1948 and it was mined until around 1970 for tin and tungsten using underground mining but, above all, open pit mining, leading to the appearance of pits.

The environmental remediation work at the Murçós mining area consisted of the following main activities:

  • Tailings Dam
    • Protection of the mouth of the drainage well;
    • Cleaning/drainage of sludge and scattered debris;
    • Forming/containment of sludge.

    • Cleaning of debris adjacent to the pit;
    • Adjustment of embankments with safety steps and proper inclination;
    • Maintenance of the respective lakes and recreation of conditions for the development of macrophytes (Typha and Juncus).
  • Pit 4
    • Filling of slopes with spoil heaps;
    • Moulding of slopes;
    • Protective fencing.

This contract was awarded to MT3 – Engenharia e Obras, Lda for 374,151.55 and had a duration of 180 days.

The investment made was co-financed by the Northern Regional Operational Programme under the Third Community Support Framework and enabled the creation of full conditions to allow people to safely use the space circumscribed by the mining area, almost completely reducing its environmental impact and creating a pleasant space for leisure duly integrated into the local environment.
