Zusammenfassung:	Emulsification is effected continuously in at least two steps. The first step involves emulsification with continuous feed of the liquid phases so as to produce an intermediate emulsion containing droplets of interior phase dispersed throughout an exterior phase substantially all of which are of size lying within the range of from about 20 to about 30 micrometres. The intermediate emulsion is then continuously fed to a final emulsification stage in which it is subjected to further shear conditions so as to produce a final emulsion containing interior phase droplets dispersed in the exterior phase substantially all of which are less than 10 micrometres in diameter. Such a continuous emulsification process can be included in a continuous "liquid membrane" extraction process, e.g. for hydrometallurgical extraction of copper.
