Abstract: Apparatus including an electrically conductive housing, an electrically non-conducting pipe carrying the slurry through the housing, one or more primary coils each encircling the pipe within the housing and having a capacitor unit coupled thereto with a capacitor unit value chosen so that a primary coil series resonance is formed close to the value of a target magnetic resonance frequency, and for each primary coil, a drive coil and associated electrical network positioned to magnetically couple the drive coil to that primary coil. An impedance monitor coupled to each electrical network measures a complex input impedance thereof. An RF transmitter transmits a signal to one or more of the electrical networks with a frequency approximately equal to the target magnetic resonance frequency, and an RF receiver receives from each electrical network magnetic resonance signals from the target and forms an output signal of detected signals.

Abstract: Apparatus for the measurement of ore in mine ore benches or ore stockpiles is disclosed, the apparatus comprising: a mobile platform, defining a platform zone, wherein the mobile platform is positionable on or above a mine ore bench or stockpile; and at least one magnetic resonance (MR) sensor comprised in the mobile platform. The MR sensor includes a main loop and a drive loop located above the main loop. A magnetic resonance sensor control system is provided and configured to control at least one of: the positioning of the at least one MR sensor relative to the platform zone and/or mine ore bench or ore stockpile; the positioning of elements comprised in the MR sensor relative to each other; electromagnetic suppression characteristics of the at least one MR sensor; and/or sensitivity of the at least one MR sensor as a function of distance of the sensor from the mine ore bench or ore stockpile.

Abstract: Apparatus for the measurement of ore in mine haul vehicles is disclosed, the apparatus comprising: a portal, defining a portal zone, wherein a haul vehicle carrying ore is positionable in or movable through the portal zone; and at least one magnetic resonance (MR) sensor comprised in the portal. The MR sensor includes a main loop and a drive loop located above the main loop. A magnetic resonance sensor control system is provided and configured to control at least one of: the positioning of the at least one MR sensor relative to the portal zone and/or ore burden; the positioning of elements comprised in the MR sensor relative to each other; electromagnetic suppression characteristics of the at least one MR sensor; and/or sensitivity of the at least one MR sensor as a function of distance of the sensor from the ore burden.
