Method of separating oil-water mixtures in which the oil is present as droplets so as to comprise the disperse phase, the mean droplet size being in the range 22 to 50 micron. Use is made of a cyclone separator having a swirl coefficient in the range 8 to 30, such as greater than 12.5, or at least 13. The swirl coefficient is defined as <IMAGE> where di is the effective diameter at the inlet to the separator d2 is the nominal separator diameter at a downstream location, and Ai is the total effective inlet area.
