Iron Ore Separator Based on the Tagged Neutron Method
摘要
Abstract
A separator for the real-time beneficiation of iron ore on a conveyor belt has been developed. The method of tagged neutrons is used to determine the elemental composition of ore. A portable neutron generator ING-27 is used as a neutron source. Characteristic gamma quanta are detected by 14 gamma detectors based on BGO crystal. Ore is separated into marketable product and tailings by a gate device controlled by neutron-analyzer signals, which checks on-line the compliance of elemental concentrations of ore with the required values. The results of the separation are discussed.
