Abstract
A centrifugal jig has a container mounted for rotation about its longitudinal axis (22), separated into an axial region (32) and a peripheral region by ragging material (41) supported by a screen (30). The peripheral region is composed of a series of hutch chambers (34) with reciprocating wall portions (45) located radially outside the screen (30), for repetitively dilating the ragging. Also disclosed is a hutch chamber construction applicable to both rotary and non-rotary jigs, having a reciprocating wall portion (45) which includes convergent wall surfaces leading to the hutch chamber concentrate outlet (44).
Claims26
