A case of inventory, characterization, risk assessment, prioritization and rehabilitation of a mining impoundment in Spain. REV. MAMYM [online]. 2022, vol.7, n.1, pp.51-61. ISSN 2519-5352.

Abstract The tailings dam known as San Cristobal II was included in 2012 in the recent inventory of abandoned mining waste facilities carried out in Spain by the IGME. A mining waste facility must have met a minimal risk level to be included in the inventory, as determined by a preliminary risk assessment technique created particularly for this purpose. The establishment of priorities for action led this mining tailings dam to occupy the first position on the list of priorities. During 2018, different rehabilitation actions were implemented, with a material execution budget of €1,241,584. This work explains the whole process followed and concludes that, when considering remediation actions, it may be interesting to perform a new, more refined, detailed, and quantitative risk assessment.
