The dense medium cyclone – past, present and future
Dunglison's model is perhaps a little more robust than Wood's as it uses a published semi-theoretical partitioning model and a published particle terminal velocity correlation to predict medium and ore partitioning, which may be why it is successful in describing both coal (low density) and mineral (high density) DMC performance.
