Magnetite Mines Ltd says a study looking at applying NextOre’s on-belt magnetic resonance ore sorting solution at its Razorback Iron project, in South Australia, has shown the potential for a significant increase in plant throughput at the asset.

The ASX-listed company said results to date indicated that Razorback ores are especially well suited to bulk ore sorting with substantial improvements to ore mass recovery demonstrated in the study, completed by NextOre (a partnership between CSIRO and industry players Advisian and RFC Ambrian).

NextOre’s solution uses an on-conveyor magnetic resonance sensor to continually sense the grade of the material on the belt. This information is used to control a diverter gate that separates material above the selected cutoff grade (accepted material) from material below that grade (rejected material).

Magnetite Mines and NextOre, in October, signed an agreement that allows the development company exclusivity over any magnetite processing applications, Australia-wide, and all iron ore applications in the Braemar (including New South Wales) for a period of four years.
