Traditionally, fine magnetite is used in DMS cyclones, as magnetite which is too coarse tends to settle out within the cyclone, causing instability (England et al, 2002). The challenge with fine magnetite, is that it can become viscous, also causing instability. It is more expensive than coarse magnetite, and its losses are also prevalent ...
