Ore Sorting Systems

Supplier: Applied Sorting Technologies

Ore sorting is a process for upgrading mineral bearing materials without the need for pre-crushing to small sizes. It involves evaluating individual rocks as they pass through a machine so as to separate them into accept and reject fractions based on their mineral content.


By providing an economical way to reject sub economic grade materials at large particle sizes, ore sorting is an ideal tool for:

  • Recovering valuable fractions from waste dumps
  • Making low grade ore deposits viable to develop
  • Accelerating cash flow & payback
  • Removing nuisance materials e.g. talc
  • Improving processing plant recoveries & efficiencies
  • Reducing transport & processing costs

Applied Sorting machines are able to handle materials ranging in size from 150mm down to around 35mm at throughput rates up to 50 tonnes per hour per machine.

Because it is possible to adjust machine sensitivity and the cut-off grade for the accept/reject split, ore sorting machines can generally be fine tuned to suit individual operating requirements e.g. high upgrade ratios or maximum recoveries etc.

The engineers responsible for designing and building Applied Sorting machines have each been in the business for over 20 years. Their machines have demonstrated their durability and value in remote mines in India, Africa, Finland and North America as well as remote parts of Australia.

Applied Sorting specialises in conductivity and magnetic property sorters. These are intended for sorting sulphide ores like nickel, copper, tin etc. A technology agreement between Applied Sorting and WMC Resources enables it to offer for general sale nickel sorting machines it designed specifically for WMC and which have proved their reliability at WMC’s Kambalda and Leinster operations.

Applied Sorting can quickly assess the suitability of particular deposits or stockpiles for ore sorting by running trials on small samples of crushed rock or drill core.
