TOMRA Ore Sorting
What is ore sorting? Ore sorting is the separation of a target mineralogy, ore or element from waste at an individual particle level. The ore is sorted to remove waste and improve the efficiency and capacity of processing plant while increasing the grade. Ore sorting is. Accurate > high recovery Fast > upto 5,000 particle per sec = high tonnage Mature and proven technology Removes the variability in the plant feed 2

Sorting Creates Value in Mining! DECREASE YOUR MINING COSTS RELIABLE AND EFFICIENT SORTING DECREASE YOUR HAULAGE COSTS DIVERT YOUR ORE TYPES INCREASE PRODUCTION Reduce or remove pebbles (scats) from the milling circuit REDUCE ENERGY CONSUMPTION INCREASE YOUR DEPOSIT EXPLOITATION AND LIFE-OF-MINE RECLAIM OLD WASTE DUMPS SELL A COARSE PRODUCT REDUCE WATER CONSUMPTION REDUCE THE AMOUNT OF FINE TAILINGS Reduce the size of the TSF significantly 13
Benefits of Ore Sorting Normally 10% - 90% of the mass can be rejected in an early stage of the process at the primary, secondary or tertiary crushing stage Low grade waste rocks don t need to be transported, crushed, milled or further treated 14
