I believe this to be the result of the inefficient nature of cyclones.Screens have proved that circulating loads can be reduced to 100.Unfortunately most cyclones will report high percentages of fines back to the ball mill resulting in high recirculating loads. Applying a more efficient separation technology circulating loads are not only reduced but in many cases where multiple mills are installed are idled.

The reason for keeping the circulating load high is to keep the retention time low. The whole concept of Rob McIvors method is separate the fines soon after they are created. Running a low circulating load means you are running a high retention time and a fine particle created at the front of the mill must be delivered to the end of the mill and during the journey it is likely to be overground -- this is the inefficiency David is referring to.
