<p>Liquid-liquid extraction apparatus (10) includes a separator tank (12) rotatable about an axis extending through the tank, a tank inlet (152) for mixture of two liquids of different densities and which are substantially insoluble in each other, a tank outlet (96) on the axis of rotation for the light liquid, and a tank outlet (162) spaced from the axis of rotation for the heavy liquid. In terms of method, a mixture of the two liquids is rotated about an axis extending through the mixture to cause the light liquid to concentrate at the axis of rotation, and to cause the heavy liquid to concentrate at the periphery of the rotating liquid. The light liquid is removed from the body of liquid along a flow path co-linear with the axis, and the heavy liquid is removed from the periphery of the rotating body of liquid.</p> |
