Abstract La Parrilla is a tungsten and tin mine located in western Spain. The tailings facility has total capacity for 3 Mm will be executed four different phases. main constraint the design construction of dam that it been constructed over an existing one from 1980s. activities involved removal substitution old southern portion facility, ground improvement with gravel columns area about 10,000...

Tailings dams are constructed as storage for ore waste, serving industrial waste piles and drainage. The dam is negatively affected by rainfall, infiltration lines its own gravity, which can cause instability to gradually increase, leading deformation. To predict the irregular changes of tailings deformation, empirical mode decomposition (EMD) applied deformation data obtain trend periodic comp...

in this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. the effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. a software based experimental design approach (dx7) was applied to determine and mod...

Earthen embankments including levees, tailings dams, and earthen dams present many challenging problems for Civil Engineers, particularly in verification of their structural integrity and capacity, operation and maintenance (O&M), inspection, and safety. The sheer size and scale, age, and uncertainty of materials in these sometimes mammoth structures, all combine to present a difficult array of...

We investigated the effects of Fe-mining tailings Fundão dam on water quality, concerning physical and chemical parameters, aiming to infer recovery process affected areas, prospects quality in coming years. Water data from Gualaxo do Norte Carmo rivers were evaluated three moments: (i) before rupture (1999–2000), (ii) 1 year after (2016), (iii) implementation recover mitigation activities (201...

Different regions worldwide have adopted various approaches to tailings management, as a result of the site settings and local practices they evolved. Tailings dam failures continued occur in both developing developed countries, necessitating range management approaches. These failures, while rare, continue at frequency that exceeds industry society expectations, there is much be learned from w...
