Pipe lining abrasion testing for paste backfill operations / David Hewitt in Minerals engineering, Vol. 22 N° 12 (Octobre 2009) 

Public ISBD [article]  in Minerals engineering > Vol. 22 N° 12 (Octobre 2009) . - pp. 1088–1090 Titre : Pipe lining abrasion testing for paste backfill operations Type de document : texte imprimé Auteurs : David Hewitt, Auteur ; Sebastian Allard, Auteur ; Peter Radziszewski, Auteur Année de publication : 2009 Article en page(s) : pp. 1088–1090 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Mineral  processing  Waste  processing  Tailings  Tailings  disposal Résumé : Pipe wear in paste backfill mining operations represents a great cost to mining companies. The replacement of prematurely worn pipes results in the shut down of the entire paste system. Abrasion testing performed on various pipe lining samples yielded both quantitative and qualitative data. Both standard and non-standard methods were explored during testing. The pipe materials are ranked by their relative wear resistance as well as energy per unit mass loss. The latter may allow for better prediction of pipe wear, this in turn could prove worthwhile when scheduling maintenance downtime for such a system where cost savings would be beneficial.
