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 striles miniers sont produits partir du traitement des minerais et sont gnralement stocks derrire des barrages en remblai. La conception des barrages ncessite l'application de principes d'ingnierie solides et une comprhension des proprits des rsidus. Ce bulletin fournit un cadre pour classer diffrents types de rsidus, allant de l'ultra-fin au grossier, en fonction de leurs proprits gotechniques et propose des paramtres gotechniques typiques pour les diffrentes sortes de rsidus. Les technologies d'asschement des rsidus pour rduire le risque de stockage continuent tre dveloppes ; les diffrentes technologies, de l'paississement la filtration, en passant par l'application des anciennes technologies, sont prsentes pour illustrer les options disponibles et, le cas chant, les proprits in situ typiques. Ce bulletin s'adresse un large public d'intervenants : concepteurs, propritaires, rgulateurs, communauts et organisations diverses et fournit une rfrence pour communiquer les proprits des rsidus et les avantages et les limites des technologies. Toutes les oprations minires et, par consquent, les traitements des rsidus, sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de rsidus doit tenir compte des conditions propres au site, telles que le climat, la physiographie, la gochimie, la gomorphologie, la sismologie, les processus miniers, l'environnement et le milieu communautaire, l'application de technologies jouant un rle important dans le dveloppement de parcs rsidus srs et durables.
