  • ORE ANALYSIS SYSTEM
    Publication number: 20150123666
    Abstract: Ore analysis system including first and second sensing annular coils (12, 14; 212, 214), and an exciting annular coil (16, 216). Rock cutting samples (56) fall through the coils and create a signal depending on their magnetic properties. Data obtained from the magnetic properties measurement are used to control a mining machine.
