The RADOS XRF+ Ore Sorting Solutions

A proprietary and proven sorter - a game-changer for the mining industry

RADOS Sorting Solutions


Rados is unique in offering a complimentary suite of solutions, to provide an optimal value
proposition for client operations, including:


for lower volume operations;


for higher volume operations;


for higher volume operations, combining both bulk sorting (roughing) and particle sorting (cleaning).

Particle Sorting Solution


The Rados particle sorting solution provides strong value propositions for clients, because of the accuracy, consistency and quantum of the ore upgrade, due to:


  • Primary analysis of metal or proxy markers, rather than secondary analysis of other characteristics, such as colour and density.


  • A true particle-by-particle sort, facilitated by the Rados proprietary mechanical actuation system.


  • The robustness of the sorter, due to its state of the art applied engineering features, which ensures high availability and lower maintenance.

  • A modular system allowing for the attainment of economies of scale benefits.

Bulk Sorting Conveyer Solution


The Rados Bulk Sorting Solution provides strong value propositions for clients, due to:

  • Our unique ability to analyse and actuate in <10-second intervals, notwithstanding large variations in ROM ore particle size distribution, thereby maximising the bulk sorting value proposition.


  • The Bulk Sorter can process a wide range of sizes, and ore types requiring only an algorithm change which can be done remotely and instantaneously.

  • The Rados scanners incorporate machine learning functionality, which continuously improves the performance of the scanner.


  • The calibration process is highly automated which can be conducted without stopping the conveyor.

  • We are in the process of developing bespoke off conveyor belt in-pit bulk sorting solutions to compliment the Bulk sorting solution.

Integrated Sorting Solution

Rados is the only company able to offer this integrated solution which combines both sorting solutions in (for example) a roughing (bulk sorter) – scavenging (particle sorter) approach.


  • ROM Ore is feed through the Rados Bulk Sorter and sorted into high and low-grade ore streams.

  • The high-grade ore is sent directly to the processing plant and the lower grade ore is then crushed and screened before being fed through Rados Particle Sorting Plant.

  • The Rados Particle Sorter sorts the ore into, high-grade ore which is sent to the processing plant and low-grade ore, which is sent to the discard stockpile.

  • This integrated solution mitigates risk by maximizing recovery.




The Rados Sorting Solutions provide a platform for ore stream digitalization, by providing

real-time data and analysis, into an independent database with automated reporting capability, with potential integration into the client’s SCADA network.

The benefits include:


  • Facilitates measurement of ore grade for online metal accounting, and reconciliation of expected versus actual metal content delivered by the mine for downstream beneficiation;


  • Allows geologists to assess the accuracy of their resource model and the valuation thereof, providing real time feedback of the current sections being mined;


  • The volumetric analysis assists with optimisation of belt loading and upstream resource utilisation;


  • The feed-forward value lies in the ability to adjust the beneficiation plant incrementally ahead of time, based on the expected properties of the ore on its way from the mine.


  • Data collection allows for predictive maintenance, which reduces unexpected downtime and maintenance costs.

  • The Rados Scanner can also be used as a stand-alone analyser to real-time data.
