Hydrophobic solids are known to occur in the fine tailings produced during bitumen extraction at both the Syncrude and Suncor oil sands plants. Removal of these solids, and associated residual bitumen, produces changed settling behaviour and subsequent dewatering of the remaining tailings. In this w

In bitumen extraction of oil sands by hot water, the problem of sludge accumulation is, at least partially, attributable to the presence of unrecovered bitumen as well as acetone solubles and so called 'insoluble organic matter' (IOM) on the surfaces of inorganic particles. A comparative study of th
Improved efficiency in bitumen recovery was observed in laboratory experiments when oil sand pulp was intentionally aerated by air sparging during digestion. The mechanism of gas bubble attachment to bitumen lenses (at the surface of sand grains), the spreading of bitumen on a gas bubble and the rel
We have investigated the colloidal stability and interactions in a mixture of colloidal silica (LudoxTM) and an oil-in-water microemulsion (AOT/decane/brine). Stable silica-microemulsion mixtures containing large fractions of dispersed phase (phioil + phiLudox > 0.36) can be prepared. For fixed sili
