The benefits of heavy resins in fluidized-bed ion-exchange columns

The advantages to be gained from the use of a high-density ion-exchange resin in a uranium recovery circuit are shown. It is concluded that, in existing fluidized-bed plants, the throughput of solution can be increased by up to 40 per cent at the same uranium recovery. Alternatively, the values in the barren solution can be improved at the same flow-rate of solution.
