Comparison of the Durability of Geotextiles in an Alkaline Mine Tailings Environment

摘要: This is the last of a three-part study (Grubb et al. 1999, 2000) that explores issues related to use and durability geotextiles in Andean mining environments. Additional outdoor exposure tests were completed on woven multi-filament polyester (PET) geotextile, two nonwoven needle-punched polypropylene (PP) with carbon black Vijus, Peru, Atlanta, Georgia, USA. The average retained strengths each geotextile both locations did not exceed 60%. Five samples (those previously mentioned additional PET geotextiles) also embedded freshly deposited alkaline tailings pH 11.3 178 mg/L total cyanide. lighter varied from approximately 43 338%. four ranged 84 92%. Two placed directly surface demonstrated chemical-induced erosion processes could be...
