The Effect of Freezing and Thawing on the Dewatering of Oil Sands Sludge. IN: Proceedings of the Conference Reclamation, A Global Perspective
Download1989
Bork, P., Layte, P., Johnson, R. L.
Oil sands processing operations in northeastern Alberta generate 25 x 106 m3 of water-fines mixtures (sludge) per year. The fines settle in several weeks but will not consolidate to more than 35% solids, even over centuries. Freezing and thawing the oil sands sludge led to rapid dewatering. ...

A Summary of Land Resource and Groundwater Resource Issues Related to Plains Coal Mine Reclamation in Alberta
Download1996
Trudell, M., Moran, S. R., Cheel, D., Macyk, T., Thacker, D.
Development and extraction of coal resources in Alberta disrupts the landscape and alters two other important resources, land and groundwater. In order to support coal resource development that was economically and environmentally responsible, the Reclamation Research Technical Advisory Committee...

Revegetation of Oil Sands Tailings: Growth Improvement of Silver-berry and Buffalo-berry by Inoculation with Mycorrhizal Fungi and N2-fixing Bacteria
Download1988
The ability of actinorhizal shrubs to tolerate inhospitable conditions while improving soil fertility and organic matter status has led to increased usage of these plants for land reclamation and amenity planting purposes. Silver-berry and buffalo-berry are two such shrubs which are being tested...
