Abstract: 1536380 Gravity separation; mixing INCO Ltd 10 Nov 1977 [15 Nov 1976] 46733/77 Headings B1C and B1D [Also in Division C1] A method for separating a mixture of an aqueous phase, a liquid organic phase less dense than the aqueous phase and a solid phase denser than the aqueous phase, comprises introducing the mixture into a settler 10 in which the solid and aqueous phase settle below the organic phase to produce an interfacial region 17, 18 between bulk organic phase and bulk aqueous phase, withdrawing the organic phase from above the interfacial region, withdrawing the aqueous and solid phases from below the interfacial region, and during the separation imparting in the interfacial region a local agitation to the phases. The agitation may be effected by a stirrer 15 or by sparging gas. The solid and aqueous phases may be removed together for subsequent separation in a conventional separator, or they may be removed by separate outlets 20, 12 with further stirring means 13 operating between these outlets. The method is particularly suited for separating mixtures formed by organic solvent extraction from aqueous solutions followed by lime addition for hydrogen ion neutralisation. In such a case the interfacial agitation prevents the build-up of 'crud' (a three phase emulsion) at the interfacial region.
