Spring 2012
Tailing ponds in Northern Alberta has covered an area of 170 km2. Directive 074 issued in 2009 set stringent criteria for tailings reclamation. Freeze-thaw dewatering is one of the most promising approaches for dewatering MFT as one cycle of freeze-thaw can release up to 50% pore water. In this...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Spring 2017
Mature fine tailings (MFT) are one of the major problems of the oil sands industry in Alberta, specifically due to the reclamation of the land filled with them. Stepping away from the most common approach of dewatering processes, this research is based on the manufacture of useful composite...
