ABSTRACT: tal Assistance for Tailings Disposal Boswell, J.E.S. & Sobkowicz, J.C. Thurber Engineering, Calgary, AB, Canada ABSTRACT Traditional dewatering methods for Oil Sands tailings such as thickening, flocculation and centrifugation employed to reduce water content and improve consolidation fall short of final requirements for tailings reclamation, especially in the treatment of tailings fines. Some environmental assistance is needed to achieve the additional dewatering required, and to reach target solids contents and shear strengths for the tailings deposit. The paper outlines some key environmental methods and offers a perspective on their use.
RÉSUMÉ: Les méthodes traditionnelles d'assèchement des stériles provenant des opérations minières des sables bitumineux incluent la densification, la floculation et la centrifugation. Ces méthodes sont axées sur la réduction de la teneur en eau et l'amélioration de l'état de consolidation des stériles, et ne sont pas suffisants pour rencontrer les critères finals de réclamation des stériles, particulièrement en ce qui concerne le traitement des stériles à particules fines. Un support environnemental est nécessaire pour atteindre le niveau d'assèchement requis, ainsi que la concentration des solides et la résistance au cisaillement des dépôts des stériles désirées. Cet article souligne quelques méthodes environnementales clés et présente une perspective sur leur application. 1 INTRODUCTION
