摘要

A method and system for detecting electrically conductive objects such as tramp metal embedded in a load of mineral ore/earth within a detection space of an earth moving receptacle. A magnetic signal pulse is projected into a detection space of the receptacle by an antennae loop surrounding the detection space. The magnetic response of the system is monitored and analyzed to determine the presence or absence of electrically conductive objects in the loose material within the detection space.
