PDF Effect of circulating load and classification

The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell 2008 who used Bond ball mill tests as the base line Bond, 1962.
