Cracking Dams: Scenarios, a Cornell University
April 25, 1998: the tailings dam at the Los Frailes mine near Seville, Spain failed due to an earthslide in the bedrock below the dam. The slide was caused by excess pressure from the weight of the dam and the tailings. This shift in the earth caused the dam to shift and cracks to form in the dam. A crack at the southeast end of the damOre from the mine will be sent to the grinding section in 20t capacity dump trucks. The coarse ore will be fed to a primary jaw crusher followed by a secondary crusher. The Tahuehueto mine is accessed from Tepehuanes through a 40km paved road to Ciniega de Los Frailes, an additional 80km of unpaved road, followed by a 40km dirt road.Tahuehueto Project, Durango Mining Technology

(PDF) New approaches for extracting and recovering metals from mine
TL;DR: A two-stage mineral leaching and metal recovery protocol was developed to extract copper from tailings generated as waste materials in two mines currently operating in Spain and Serbia as discussed by the authors, where the most effective extraction of copper (84 to > 90%) was achieved by bio-leaching the tailings at The mill uses a crushing, grinding, and flotation flowsheet to recover a lead concentrate and a zinc concentrate. The Bolivar Mine is located in the Cordillera de los Azanaques, forming the western edge of the Cordillera Oriental, which is detached from the Cordillera de los Frailes, belonging to the group of central mountain rangesBolivar Mine, Bolivia Santacruz Silver Mining Ltd.

The Los Frailes tailings dam failure (Aznalcóllar, Spain)
Resources. On April 25, 1998, a tailings dam failure of the Los Frailes lead-zinc mine at Aznalcóllar near Seville, Spain, released 4-5 million cubic meters of toxic tailings slurries and liquid into nearby Río Agrio, a tributary to Río Guadiamar. The slurry wave covered several thousand hectares of farmland, and it threatens the DoñanaEnvironmental accidents involving mining companies, such as Brumadinho (in Minas Gerais, Brazil), Bento Rodrigues (Modena and Heller 2016) and Los Frailes (Achterberg et al. 1999) dam ruptures, have increased the level of concern from communities and governmental agencies over tailings management, and new rules for Mass and Metallurgical Balance Forecast for a Zinc Springer
