PCT No. PCT/GB84/00164 Sec. 371 Date Dec. 27, 1984 Sec. 102(e) Date Dec. 27, 1984 PCT Filed May 15, 1984 PCT Pub. No. WO84/04707 PCT Pub. Date Dec. 6, 1984.An apparatus for ore sorting includes a neutron irradiator (12), and a detector assembly (14) for detecting gamma radiation emitted by irradiated lumps (21) of the ore. The irradiated lumps (21) after discharge from the irradiator (12), are divided into two channels (30) by at least one bifurcating device (28) held above a relatively high speed conveyor (26) transporting the lumps (21). Each channel (30) is subsequently divided into three streams (37, 38, 39) by diverting selected lumps (21) from the channel (30) as the lumps (21) are projected from the end of the high speed conveyor (26). The diverted lumps (21) in each stream (37, 38, 39) are allowed to fall on to a relatively low speed conveyor (50) which then presents the lumps (21) to the detector assembly (14). |
