... components in the ore. This association between the mineral and bitumen components results in a decrease in bitumen recovery, poorer froth quality, or both. Quantification of the surfactant partitioning between the hydrocarbon and water phases has been related to bitumen recovery for a variety of naturally...

... Introduction One of the goals in oil sands development is to process poorer quality oil sands while reducing energy consumption. To achieve this goal, it is necessary to optimize the two main stages of oil sands processing: extraction and froth treatment. The most common extraction process...

... poorer quality ores; that is ores with less bitumen and more fines. At the same time, it is desirable to reduce the process energy requirements. There are two main stages to oil sands processing: extraction and froth treatment. The most common extraction process is hot water bitumen extraction where...

... of the Suncor Steepbank mine, areas of ore were identified that created processing difficulties, in particular high froth densities. The high froth densities resulted in problems in downstream facilities where high solids content in the froth resulted in overloading of the froth treatment centrifuges...
