DISPLACEMENT ERROR CORRECTION IN SORTING SYSTEMS

摘要

A B S T R A C T In radiometric sorting a method of compensating for the count recorded by a detector for an ore particle which is displaced from the centre line of the detector. The compensation is effected by applying one of a plurality of calibration factors to the detector count. The calibration factors are statistically determined and are dependent on the measured displacement and optionally on at least one of the shape, height, volume or mass of the particle.
