Oil sands are naturally occurring mixtures of sand or clay, water, fine silts, and bitumen. The oil sands extraction process consumes large volumes of water (i.e., ca. 3 barrels of fresh water for every 1 barrel of oil). Following the extraction of bitumen from the oil sands, a tailings slurry...

The oil sands bitumen extraction process results in the creation of waste products including oil sands process-affected water (OSPW) and mature fine tailings (MFT). Many technologies are currently under investigation to treat these waste products that are currently contained in vast storage...

There are many candidate technologies that could be applied to the treatment of oil sands process-affected water (OSPW). Advanced oxidation processes (AOPs) are particularly useful for degrading biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents,...

The accumulation of mature fine tailings (MFT) in tailings ponds with very slow natural consolidation rate has been a concern for decades. Previous studies and current practices for tailings consolidation focus on the addition of various inorganic and organic additives to reduce MFT production...

Oil sands mining involves removal of water from the Athabasca River basin in northeastern Alberta. Water produced during the extraction of bitumen from oil sands is referred to as oil sands process water (OSPW). Information on the likelihood of human exposure to OSPW derived naphthenic acids...

Large volumes of oil sands process-affected water (OSPW) are produced by the surface-mining oil sands industry in Alberta. The industry is following a no-release practice for OSPW due to its potential environmental toxicity. Both laboratory and field studies have demonstrated that OSPW is toxic...
