Because RF fields penetrate tens of centimetres into most ores, the method can be applied to rocks, slurries or concentrate powders of large volumes, without the need for any sample preparation.
The presence of one mineral does not affect the capacity to sense another. The lack of overlapping mineral response frequencies mean that the MR method is very highly specific to the measurement of key minerals. There is no complicated spectral analysis or “background” stripping required; the magnitude of the MR echo is all that is used to estimate the mineral mass in the measurement zone.
No complicated calibration
Because the MR measurement is especially “clean”, there is no requirement for extensive calibration campaigns; often an accurate factory calibration can be pre-set.
Insensitive to surface conditions and moisture
As MR is a true bulk sensing technology, the measurement does not require presentation of clean surfaces, narrow size distributions, or premixed presentation to achieve a reliable measurement.
Fast, accurate measurement
The speed of bulk measurement outperforms all other technologies, such as nucleonic based techniques, leading to maximum achievable grade uplift in compact sorting applications. MR technology has been proven to result in sensing resolutions as precise as 0.047% copper in mining applications.
