    摘要： Middlings from the primary separation vessel ("PSV") are recycled through a line to the PSV. The middlings are aerated with fine air bubbles using in line eductor/aerator assemblies. The aerated middlings are mixed as they are pumped through a line back to the PSV. Bitumen recovery from the PSV is increased as a result.

    摘要： Average grade oil sand is mixed with water to produce a low temperature (20-35.degree. C.), dense (1.4-1.65 g/cc) slurry. The slurry is pumped through a pipeline for sufficient time to condition it. Air is injected into the slurry after the last pump. The slurry density is adjusted to about 1.5 g/cc by adding flood water near the end of the pipeline. The slurry is introduced into a primary separation vessel slurry as it is introduced into the (PSV), excess air is vented from the PSV and a hot water underwash is used to heat the froth produced. Slurry loading to the PSV is greater than about 4.78 tonnes of oil sand/hour/square meter to reduce velocity gradient in the fluid in the vessel. Bitumen froth is recovered. When fed low grade oil sand, the process is modified by adding flotation aid chemicals to the slurry in the pipeline and subjecting the PSV tailings and middlings to secondary recovery with agitation and aeration in a secondary separation vessel.

    摘要： A large, mechanically agitated pump box is used between a mixer, for mixing oil sand and water to produce a slurry, and a pipeline for conveying the slurry to a processing facility. Prior to the aqueous slurry being discharged into the pump box from the mixer, it is screened to reject large solids. The oversize is directed to an impactor where it is comminuted and the comminuted product is screened again prior to being discharged into the pump box. The pump box is designed to increase the residence time of the slurry in the pump box and to separate the slurry into two phases, the suspended slurry and the larger lumps that cannot be suspended. The larger lumps that settle in the pump box are recycled to the impactor for comminution.

    摘要： A dispersant, such as sodium silicate, is added to the process water of the hot water extraction process which recovers bitumen from oil sands. The dispersant disperses the ultrafine (less than 300 nm) particles, to reduce the formation of flocs and sludge in the tailings pond. The volume of the pond is such that the retention time of process water is sufficiently short (less than 6 weeks when using sodium silicate) to avoid reforming flocs from the dispersed ultrafines. The ultrafines content in the process water builds up as the water is repeatedly recycled from the pond to the extraction process. The ultrafines content stabilizes at a steady state concentration as some ultrafines are continuously removed from the process water when the tailings are delivered onto the "beach" of the pond and become trapped in the sand.

    摘要翻译： 将分散剂如硅酸钠加入到从油砂中回收沥青的热水提取过程的工艺水中。 分散剂分散超细（小于300nm）颗粒，以减少尾矿池中絮凝物和污泥的形成。 池塘的体积使得工艺水的停留时间足够短（使用硅酸钠时少于6周），以避免从分散的超细粉中重整絮凝物。 随着水从池塘重复循环到提取过程，工艺中的超细含量积聚起来。 超细含量稳定在稳态浓度，因为当尾矿物被运送到池塘的“海滩”上时，一些超细细菌从工艺水中被连续地除去并被困在沙子中。

    摘要： A process suitable for operation at a mine site for recovering a hydrocarbon from a hydrocarbon bearing sand comprising the steps of mixing a chemical additive with a chemical composition and with a hydrocarbon bearing sand containing hydrocarbon and residual solids including clay, at a temperature to form a slurry. The chemical composition comprises an aqueous phase and a minor amount of a chemical agent selected from the group consisting of at least one ethoxylated alkylphenol compound, at least one ethoxylated dialkylphenol compound, MIBC, SC-177, Petronate HL, Calcium Lignosulfonate, NaOH and mixtures thereof. The slurry is conditioned and aerated to produce essentially sludge-free tailings and a mixture of hydrocarbon, aqueous phase and residual solids including clay. The process further comprises the step of separating in a short-residence time apparatus the mixture of the hydrocarbon, the aqueous phase and the residual solids including clay from the essentially sludge-free tailings.
