DMS Cyclone Efficiency Factors: The De Beers Perspective

Diamonds have a density of 3.5 g/cm3, in an ideal diamond separation the material above the density of 3.3 g/cm3 has to report to sinks. Figure 1 indicates that as the feed rate is varied the separation efficiency deteriorates especially near the diamond density material of 3.5 g/cm3; this indicates that as feed rate increases
