A centrifugal jig of the type in which a feed slurry is introduced into a container (40) rotating about a vertical axis within a region (51) radially bounded by a screen (52) provided with ragging on its inner surface, water in the hutch region (54) beyond the screen being pulsed repetitively to dilate the ragging, in which pulsion of the hutch water is achieved at an interface such as a diaphragm (57) or an air/water interface (101) which is substantially wholly located beyond the projected free surface of the feed material. The screen (52) is substantially parabolic. |
