Description


Tailings are produced from the processing of mineral ores and are commonly stored within embankment dams. The design of the dams requires application of sound engineering principles and an understanding of the properties of the tailings. This Bulletin provides a framework for classifying different types of tailings, ranging from ultra-fine to coarse, based on their geotechnical properties and provides typical geotechnical parameters for the different tailings types. Technologies for dewatering tailings to reduce the risk of storage continue to be developed and the different technologies, from thickening to filtration, and re-application of old technologies are presented to illustrate the options available and, where appropriate, typical in situ properties. This bulletin is directed towards a wide audience of stakeholders: designers, owners, regulators, communities and various organizations and provides a reference for communicating tailings properties and the benefits and limitations of technologies. All mining operations, and thereby tailings operations, are unique. There is no one-solution-fits-all. Tailings dam designs need to account for site-specific conditions, such as climate, physiography, geochemistry, geomorphology, seismology, mining processes, environment, and community setting, with the application of technologies playing an important role in developing safe, sustainable tailings facilities.

Les st riles miniers sont produits partir du traitement des minerais et sont g n ralement stock's derri re des barrages en remblai. La conception des barrages n cessite l'application de principes d'ing nierie solides et une compr hension des propri t's des r sidus. Ce bulletin fournit un cadre pour classer diff rents types de r sidus, allant de l'ultra-fin au grossier, en fonction de leurs propri t's g otechniques et propose des param tres g otechniques typiques pour les diff rentes sortes de r sidus. Les technologies d'ass chement des r sidus pour r duire le risque de stockage continuent tre d velopp es; les diff rentes technologies, de l' paississement la filtration, en passant par l'application des anciennes technologies, sont pr sent es pour illustrer les options disponibles et, le cas ch ant, les propri t's in situ typiques. Ce bulletin s'adresse un large public d'intervenants: concepteurs, propri taires, r gulateurs, communaut's et organisations diverses et fournit une r f rence pour communiquer les propri t's des r sidus et les avantages et les limites des technologies. Toutes les op rations mini res et, par cons quent, les traitements des r sidus, sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de r sidus doit tenir compte des conditions propres au site, telles que le climat, la physiographie, la g ochimie, la g omorphologie, la sismologie, les processus miniers, l'environnement et le milieu communautaire, l'application de technologies jouant un r le important dans le d veloppement de parcs r sidus's rs et durables.

About the Author


The Commission Internationale des Grands Barrages (CIGB) / International Commission on Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.
