Thermal properties of oil sands fluid fine tailings: laboratory and in situ testing methods

Abstract: Fluid fine tailings (FFT) are soft tailings produced by the bitumen extraction process associated with open-pit oil sands mining. Oil sands mine operators have proposed the use of end pit lakes (EPLs) to contain soft tailings and Syncrude Canada Ltd. has developed the first EPL in the industry. This EPL, referred to as Base Mine Lake, contains FFT transferred from an above-ground tailings facility in a mined-out pit. The FFT was placed at elevated temperatures relative to natural groundwater temperatures in th… Show more

“…Water samples were collected for both geochemical and microbiological characterization. Bulk water was retrieved in a 6.2 L Van Dorn bottle (Wilco, model Beta ® , Wildco, Yulee, FL, USA), while FFT was sampled using a custom-built fixed interval sampler as described in Mori et al [ 14 ] and Dompierre et al [ 32 ].…”

“…1. A detailed description of BML has been provided in previous studies (2,9). Briefly, the original mining pit located on this site (West-In Pit, WIP) was begun in 1978 and converted into a tailings pond in 1994.…”

“…From 1994-2012 it was gradually filled with FFT to a depth of 45-50 m, and in 2012 capped with an additional 5 m of fresh water, forming the present end pit lake, renamed Base Mine Lake. There is no outflow from BML to the local watershed, but the water level is maintained at 308.7 metres above sea level via pump-in of freshwater or pump-out of excess water to the extraction plant (2). Due to gradual FFT settling and dewatering, the depth of the water cap increased to approximately 10-12 m by 2019.…”
