    Abstract: A method of preparing a water in oil emulsion comprises forming a mixture of oil and emulsifying agent, progressively adding an aqueous salt solution to the mixture and dispersing the aqueous salt solution into the mixture. A concentrated water in oil emulsion is formed with drops of the aqueous salt solution (1) packed inside the oil solution phase (2). The emulsion is added to water and then mixed so that the emulsion absorbs the water. The salt concentration of the emulsion relative to the salt concentration of the water is controlled. Methods of agglomerating fine hydrophobic particles in a slurry using the water in oil emulsion are provided, where the emulsion is added to the slurry and then mixed so that the emulsion absorbs the water in the slurry. The salt concentration of the emulsion relative to the salt concentration of the slurry is controlled.

    Abstract: This disclosure relates generally to selective flocculation, and more particularly to portable test-device for performing selective flocculation experiments in continuous mode. The test-device includes a slurry inflow system, a flocculant tank, a static mixer, a control pumping system, and a thickener system. The static mixer is connected to the slurry inflow system and the flocculant tank, to receive and mix flocculant solution and slurry and cause formation of floc. The control pumping system connects the flocculant tank and the slurry inflow system to the static mixer to control the control parameters responsible for pumping the slurry and flocculant solution in the continuous mode in the static mixer. The thickener system comprises a thickener tank to receive treated slurry and the floc from the static mixer, separately collect tailings and the floc from the thickening tank. The components of the portable test-device are removably connected to each other.

    Abstract: A flocculant, according to embodiments of the present disclosure, includes a core nanoparticle and at least one positively charged functional group on a surface of the core nanoparticle. The nanoparticle may comprise a silica, alumina, titania, iron oxide, iron nitride, iron carbide, or a carbon-based nanoparticle. The flocculant may be used, in a method of bitumen recovery, to neutralize and agglomerate bitumen droplets and/or mineral particles derived from oil sands ore. The bitumen droplets agglomerate about the core nanoparticle of the flocculant to form bitumen flocs, while the mineral particles agglomerate about the core nanoparticle of the flocculant to form mineral flocs. The buoyant bitumen flocs may then separate from the dense mineral flocs to enable high-yield recovery of bitumen from oil sands.
