A process is provided for selectively recovering nickel by ion exchange absorption from a Ni/Co sulfuric acid feed solution (6) obtained from limonite ore (1) which is pressure leached with sulfuric acid (2) and then neutralized (3) and solid/liquid separated (4), containing nickel in the range of about 0.5 to 40 gpl and cobalt in the range of about 0.01 to 2 gpl as sulfates. Tailings disposal occurs at (5). The process comprises contacting the acid solution at a pH ranging from about 0.3 to 6 with a bed of protonated ion exchange resin in which protons thereof are exchangeable with nickel ions in said solution during ion exchange (7). The nickel is selectively extracted in preference to cobalt from the solution at a pH of less than about 2, thereby forming a raffinate containing the cobalt (8). The cobalt raffinate is neutralized (9), solid/liquid separated (10) and cobalt recovered therefrom (11, 12). Raffinate depleted in cobalt is sent (13) to tailings disposal (5). The absorbed nickel is stripped from said resin with sulfuric acid (16) to form a nickel sulfate solution characterized by a nickel to cobalt ratio of at least about 50:1 suitable for the recovery of substantially pure nickel by electrolysis (15). Prior to electrolysis the nickel sulfate solution is neutralized (8A) and solid/liquid separated (14).

Fresh green vanilla beans of a recent harvest, or partially cured vanilla beans or preserved green vanilla beans are used as the starting material. A preparation containing natural tea enzyme is made from fresh tea leaves. Fresh/cured/preserved vanilla beans, after proper size reduction, are mixed in a suitable proportion with the tea enzyme preparation and incubated to facilitate action of natural enzymes on vanilla flavour precursors present in the beans. The fermented vanilla & tea enzyme mix is treated with ethanol to inactivate enzymes and to extract the vanilla flavour constituents into ethanol. This is followed by separation of solid phase from liquid phase and clarification, to obtain vanilla extract having characteristic flavour, appearance and acceptable vanillin content.

Described herein is 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, and, solids are agitated within the slurry to form an agglomerated slurry comprising agglomerates and a low solids bitumen extract. In order to control agglomeration, the slurry is analyzed and the processing method is adjusted accordingly.

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.

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.

A process is described for bitumen extraction from oil sands. Solvent extraction is used, incorporating fines agglomeration to simplify subsequent separation. A high quality bitumen product is formed, having water and solids content that exceeds downstream processing and pipeline requirements. An embodiment of the process comprises combining a first solvent and a bituminous feed to form an initial slurry, which is optionally separated into fine solids and coarse solids. Solids are agglomerated to form an agglomerated slurry. A low solids bitumen extract from the agglomerated slurry is mixed with a second solvent to form a solvent-bitumen low solids mixture, the second solvent having a similar or lower boiling point than the first solvent. The mixture is separated to produce high grade and low grade bitumen extracts. The first and second solvents are recovered from the high grade bitumen extract, leaving a high grade bitumen product.

Processes are described for extracting hydrocarbon from a mineable deposit, such as bitumen from oil sands. The integration of solvent-based extraction processes with aqueous extraction processes is described. In one embodiment, water is removed from an aqueous bituminous feed that is then directed into a solvent-based extraction process. In another embodiment, a stream produced through solvent extraction is directed into a water-based extraction process. In the solvent-based extraction processes, agglomeration of fines may be employed to simplify subsequent solid-liquid separation. The process permits recovery of hydrocarbon that has conventionally may have been too difficult to recover from oil sands processing, and thus has previously been lost. Advantageously, a fungible product can be formed more efficiently according to certain integrated processes described herein.

Disclosed is a method of processing bitumen streams using membrane filtration. In one aspect, membrane filtration replaces paraffinic froth treatment, with one or more filtration steps replacing gravity settling. In another aspect, the bitumen stream is subjected to paraffinic solvent treatment at much higher flow rates, with an "almost cleaned" product being subsequently filtered by the membrane system. In this case, some contaminants are removed by conventional gravity settling equipment, while additional contaminants are removed by membrane filtration. In another aspect, membrane filtration is applied to a bitumen product effluent stream following naphthenic froth treatment. In another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent-based extraction process. In yet another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent extraction with solids agglomeration process. In still another aspect, membrane filtration is applied to bitumen produced by SAGD.
