    摘要: Described is a method of processing a bituminous feed. The bituminous feed is solvent extracted to form a bitumen-rich stream and a bitumen-lean stream. Solvent is recovered from the bitumen-rich stream to form a bitumen product. Solvent and water are recovered from the bitumen-lean stream to form dry tailings with a moisture content of less than 40 wt.%. The dry tailings are separated into at least two streams, each stream having a moisture content of less than 40 wt. %, based on at least one physical or chemical property. At least one of the at least two streams is then used at an oil sands mine site. In this way, the dry tailings may be used more effectively.

    摘要: The present disclosure relates to a method of processing a bituminous feed. The bituminous feed is contacted with an extraction liquor to form a slurry. A bridging liquid is added to the slurry in at least two stages and solids within the slurry are agitated to form an agglomerated slurry comprising agglomerated solids and a low solids bitumen extract. The agglomerates are then separated from the low solids bitumen extract. Potential benefits may include the production of smaller and more uniform agglomerates. The former may lead to higher bitumen recoveries and the latter may improve the solid-liquid separation rate. The bridging liquid may be added in an area of relatively high shear rates. Between stages of bridging liquid addition, agglomerates may be removed.

    摘要: The present disclosure relates to a method of processing a bituminous feed. The bituminous feed is contacted with an extraction liquor to form a slurry. The slurry is then flowed through a pipeline. A bridging liquid is added to the slurry to assist agglomeration. Agitation is also used to assist agglomeration. The result is an agglomerated slurry comprising agglomerates and a low solids bitumen extract. The agglomerates are then separated from the low solids bitumen extract. Performing the agglomeration in a pipeline as opposed to in a conventional agitating vessel may provide certain advantages, such as improved sealing in order to contain the potentially flammable mixture of oil sands slurry from the atmosphere, production of smaller and more uniform agglomerates due to improved mixing of the bridging liquid into the oil sands slurry, and the flexibility to have a long residence time for the extraction and agglomeration processes.

    摘要: System and methods for remediating a slurry pond are disclosed herein. A method includes distributing a material over a surface of the slurry pond, wherein the slurry pond includes residues from a plant operation. A method also includes placing a load on the material, wherein the load causes the material to sink below a level of a supernatant but to remain above a layer of sludge in the slurry pond.

    摘要: Systems and methods for dewatering mine tailings with water-absorbing polymers. The systems and methods may include combining a mine tailings slurry, which includes mine tailings and water, with a water-absorbing polymer. The water-absorbing polymer may absorb water from the mine tailings, thereby increasing a solids content of the mine tailings. The mine tailings may be combined with the water-absorbing polymer prior to, during, and/or subsequent to transfer of the mine tailings to a mine tailings dewatering and/or disposal site. In some embodiments, the water-absorbing polymer may be an encapsulated water-absorbing polymer.

    摘要: Systems, compositions, and methods for dewatering and/or increasing a mechanical strength of mine tailings. These systems, compositions, and methods may include combining mine tailings with wicking fibers to form a composite mine tailings mixture. The wicking fibers may provide a conduit for the removal of fluid from the composite mine tailings mixture. The composite mine tailings mixture further may include a binder that may decrease repulsive forces among fine particles that comprise the mine tailings and/or increase attractive forces among the fine particles, leading to a separation of the fine particles from at least a portion of the fluid contained within the composite mine tailings mixture. The composite mine tailings mixture may be placed in a storage or dewatering area as a composite mine tailings mixture deposit, which may include internal structure, such as layers of the composite mine tailings mixture and/or long-range orientation of the wicking fibers contained therein.
