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: The present invention provides a method and apparatus for agglomerating hydrophobic particles from a feed slurry. The method comprises adding a binder to a feed stream and conveying the feed stream and binder to an agglomerating device. The binder comprises 50% or more by volume of a non-hydrophobic substance. A high shear is applied to the feed stream and the binder in the agglomerating device to cause the hydrophobic particles to collide and bind to the binder, thereby agglomerating the hydrophobic particles. The agglomerated hydrophobic particles and the binder are removed from the feed stream. A method and apparatus for dewatering an agglomerated product is also provided, the agglomerated product comprising agglomerated hydrophobic particles held together by a binder comprising 50% or more by volume of a non-hydrophobic substance.
